How to run a static initializer method in C# before the Main() method?

In C#, you can run a static initializer method before the Main() method by using a static constructor. A static constructor is a special type of constructor that is called automatically before the first instance of the class is created or any static members are referenced.

Here's an example:

using System;

public static class Program
{
    static Program()
    {
        // Run the static initializer method here
        Initialize();
    }

    public static void Main()
    {
        // Your program code here
    }

    private static void Initialize()
    {
        // Your static initializer method code here
    }
}

In this example, we define a static constructor for the Program class, which calls a static initializer method called Initialize(). When the program is run, the static constructor is called automatically before the Main() method, and the Initialize() method is executed.

Note that if you have multiple static constructors in your program, they will be called in the order they appear in the code. If you have multiple classes with static constructors, the static constructors for each class will be called in the order they are referenced in your program.
