C# code:

csharp
 
 
Copy code
public string FormatPhoneNumber(string phoneNumber)
{
    // Remove all non-numeric characters from the phone number
    var cleanedPhoneNumber = new string(phoneNumber.Where(char.IsDigit).ToArray());

    // If the cleaned phone number has less than 10 digits, return it as is
    if (cleanedPhoneNumber.Length < 10)
        return cleanedPhoneNumber;

    // If the cleaned phone number has more than 10 digits, keep only the last 10 digits
    if (cleanedPhoneNumber.Length > 10)
        cleanedPhoneNumber = cleanedPhoneNumber.Substring(cleanedPhoneNumber.Length - 10);

    // Format the phone number as "90 xxx xxx xx xx"
    return string.Format("90 {0} {1} {2} {3}",
        cleanedPhoneNumber.Substring(0, 3),
        cleanedPhoneNumber.Substring(3, 3),
        cleanedPhoneNumber.Substring(6, 2),
        cleanedPhoneNumber.Substring(8, 2));
}

This method takes a phoneNumber string as input, removes all non-numeric characters from it, and then formats it as "90 xxx xxx xx xx". If the phone number has less than 10 digits, it is returned as is. If it has more than 10 digits, only the last 10 digits are kept for formatting.

C# code to generate a random password with a length of 10 in .NET Core 6:

csharp
 
 
Copy code
using System;
using System.Linq;

class Program
{
    static void Main(string[] args)
    {
        int length = 10;
        string chars = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789!@#$%^&*()_+";
        var random = new Random();
        string password = new string(Enumerable.Repeat(chars, length)
          .Select(s => s[random.Next(s.Length)]).ToArray());
        Console.WriteLine(password);
    }
}

This code generates a random password that includes upper and lower case letters, digits, and special characters. The length of the password is specified by the length variable. Replace the value of this variable with any desired length.

The chars string specifies all the different characters that may be included in the password. You may modify this string to include or exclude certain characters depending on your needs.

To generate a random password, this code uses the Random class to randomly select characters from the chars string. The resulting characters are concatenated into a string using the string constructor and the Enumerable.Repeat, Select, and ToArray methods from the System.Linq namespace. Finally, the resulting password is printed to the console using Console.WriteLine.

This is a task that requires more detailed explanations and it involves creating multiple classes and forms. Here is an outline of the steps you could follow:

1. Create a class named Airport which will hold the information about an airport such as name, city, country, and whether it's open or closed. Also, include a property that has a list of 20 planes for that airport.

csharp
 
 
Copy code
public class Airport {
   public string Name { get; set; }
   public string City { get; set; }
   public string Country { get; set; }
   public bool IsOpen { get; set; }
   public List<Plane> Planes { get; set; }
   // ...
}

1. Create a Plane class that includes properties for plane's model, serial number, maintenance date, and passenger capacity.

csharp
 
 
Copy code
public class Plane {
   public string ModelNumber { get; set; }
   public string SerialNumber { get; set; }
   public DateTime MaintenanceDate { get; set; }
   public int PassengerCapacity { get; set; }
   // ...
}

1. Create a form that displays a combo box of countries. Once a country is selected, populate another combo box with its cities, and when a city is selected, populate another combo box with its airports.

2. When the airport is selected, display the details of the selected airport, including the list of planes and their details.

3. When the user selects a plane, the form should display its details.

4. When the user tries to book a ticket, check if there is enough space on the plane. If yes, update the plane's passenger count and save the changes. If no, display an error message.

Keep in mind that this is just a rough outline of what the program should look like. It is recommended that you further research and break down the tasks into smaller, more manageable parts. Here are a few resources that you might find helpful:

Evet, 'for' döngüsünde değişkenin başlangıç değerini en yüksek değerden, bitiş değerini en düşük değerden, döngü değişkeninin değerini de azaltacak şekilde ayarlayarak en yüksekten en düşüğe doğru iterasyon yapabilirsiniz.

Aşağıdaki örnek doğrudur:

c#
 
 
Copy code
for (decimal fiyat = EnYuksek; fiyat >= EnDusuk; fiyat -= SatimAdim)
{
    var SatisFiyat = fiyat;

    var HedefFiyat = fiyat - AlimAdim;
}

Burada döngü değişkeni olan 'fiyat' değişkeninin başlangıç değeri EnYuksek, bitiş değeri EnDusuk, adımı SatimAdim olarak ayarlandı. Döngü değişkeni her iterasyonda SatimAdim kadar azaltıldı. Bu şekilde en yüksekten en düşüğe doğru iterasyon gerçekleştirilmiş oldu.

To load a database from DBeaver into Azure Service Bus, you need to follow these high-level steps:

1. Download and install the Azure Service Bus Explorer tool.
2. Get the connection string for your Service Bus namespace.
3. Install the appropriate Azure Service Bus NuGet package in your project.
4. Create a new topic or queue in your Service Bus namespace.
5. Use the SendAsync method to send the data from DBeaver to the Service Bus topic or queue.

Here is some sample C# code showing how to use the Azure Service Bus library to send messages to a topic:

c#
 
 
Copy code
using Azure.Messaging.ServiceBus;
using System.Text;
using System.Threading.Tasks;

// Get the connection string for your Service Bus namespace
string connectionString = "your_connection_string";

// Create a Service Bus client instance
await using var client = new ServiceBusClient(connectionString);

// Create a message sender for the topic
ServiceBusSender sender = client.CreateSender("your_topic");

// Create a message to send
string dataFromDBeaver = "your_data_from_dbeaver";
ServiceBusMessage message = new ServiceBusMessage(Encoding.UTF8.GetBytes(dataFromDBeaver));

// Send the message to the topic
await sender.SendMessageAsync(message);

For more detailed information, please refer to the official Microsoft documentation on using Azure Service Bus: https://docs.microsoft.com/en-us/azure/service-bus-messaging/

There could be a few reasons why your email text is not updating in a C# generated email. One possible cause could be that the email message body is not being updated with the new text content.

To update the email text, ensure that you are setting the message body property in your C# code to the updated text content. Here is an example of updating email text using the System.Net.Mail namespace in C#:

csharp
 
 
Copy code
using System.Net.Mail;

// create a new MailMessage object
MailMessage message = new MailMessage();

// set the recipient, subject, and message body properties
message.To.Add("recipient@example.com");
message.Subject = "Email Subject";
message.Body = "Original email text content.";

// update the email text content
message.Body = "Updated email text content.";

// create a new SmtpClient object and send the message
SmtpClient client = new SmtpClient("smtp.example.com");
client.Send(message);

If this does not solve your issue, there may be other factors at play. Be sure to review your code and email configuration settings for potential issues.

To call a TypeScript function from within a C# function, you can make use of JavaScript Interop concepts. You can use the IJSRuntime and InvokeAsync method to make a call to JavaScript function from C# code. With the help of TypeScript, you can expose the required function as a global function in the JavaScript runtime.

Here's an example of how you can call a TypeScript function helloWorld() from a C# function:

csharp
 
 
Copy code
// Import the required namespace
using Microsoft.JSInterop;

public class MyClass
{
    // Inject the IJSRuntime dependency
    private readonly IJSRuntime _jsRuntime;

    public MyClass(IJSRuntime jsRuntime)
    {
        _jsRuntime = jsRuntime;
    }

    public async Task CallTypeScriptFunction()
    {
        // Call the TypeScript function with the InvokeAsync method
        await _jsRuntime.InvokeVoidAsync("helloWorld");
    }
}

TypeScript code:

typescript
 
 
Copy code
// Declare the TypeScript function and export it
export function helloWorld(): void {
  console.log("Hello World from TypeScript!");
}

Note: You will need to pass the IJSRuntime dependency to the C# function in order for the above code to work. You can check the docs for more information on how to inject IJSRuntime into a component or class.

The various programs used to create virtual reality experiences depend on the developer's goals and resources. Commonly used programs include Unity3D, Unreal Engine, and CryEngine. Unity3D is one of the most popular and versatile game engine and allows developers to quickly create VR experiences using their suite of tools and assets, as well as custom coding in C#, C++ and JavaScript. Unreal Engine is a professional-level engine used to create high-end graphics and experiences. It is popular among experienced developers and less accessible to beginners. CryEngine is capable of creating photo-realistic visuals and is often used to create advanced simulations.

The following example demonstrates how to create a simple implementation of the popular game Battleship using the C# programming language:

c#
 
 
Copy code
// Set game board size
const int BOARD_SIZE = 10;

// Set boats
int[,] boats = { { 0, 0, 1, 1, 0 }, 
                 { 1, 0, 0, 0, 0 },
                 { 0, 0, 0, 1, 1 },
                 { 1, 0, 0, 0, 0 }, 
                 { 0, 0, 0, 0, 0 } };

int hits = 0;

// Create game board
// # - water
// X - boats
// O - fired
char[,] board = new char[BOARD_SIZE, BOARD_SIZE];
for (int i = 0; i < BOARD_SIZE; i++) 
{
    for (int j = 0; j < BOARD_SIZE; j++)
    {
        board[i, j] = boats[i, j] == 1 ? 'X' : '#';
    }
}

// Play and print
while (true)
{
    int row, col;
    Console.WriteLine("Enter row and column to fire at (i.e. 2 4):");
    var s = Console.ReadLine();
    var arr = s.Split(' ');
    row = int.Parse(arr[0]);
    col = int.Parse(arr[1]);

    if (row < 0 || row >= BOARD_SIZE || col < 0 || col >= BOARD_SIZE)
    {
        Console.WriteLine("Invalid move");
    }
    else if (board[row, col] == 'X')
    {
        board[row, col] = 'O';
        hits++;
        Console.WriteLine("Hit!");
    }
    else
    {
        board[row, col] = 'O';
        Console.WriteLine("Miss");
    }

    // Print
    Console.WriteLine();
    for (int i = 0; i < BOARD_SIZE; i++)
    {
        for (int j = 0; j
