在静态类中如何调用该方法

Question

My code is as follows

   class MyStaticClass
   {

     static MyStaticClass{};

    public static readonly MyStaticClass Instance = CreateMe();
    public static int GetSomeValue = GetValue();

    private static int GetValue()
    {
        return 0;
    }

    private static MyStaticClass CreateMe()
    {
        Console.WriteLine("This method was called");
        return new MyStaticClass();
    }

}

public class Program {

    public static void Main()
    {

         int val=MyStaticClass.GetSomeValue;

    }
 }

O/p:

This method was called

When I call val why does the debugger accesses CreateMe method ? Is it that any static method I access it will access all the static methods in the class ?

Answer 1

The method CreateMe() is called because you are calling in when you create object Instance in the following statement.

 public static readonly MyStaticClass Instance = CreateMe();

This is static object in your class and is created as you access the class which you did by MyStaticClass.GetSomeValue .

Dubugging the code will give you clear view of the order of the statements get executed. You can go through this detailed article on MSDN regarding debugging Debugger Roadmap

Answer 2

You have a static initializer for a static field. As part of program startup, all static fields are evaluated.

Edit: small clarification here:

The static fields in a particular class are evaluated in declaration order, but there in no particular order for which class has it's static fields initialized first. Now, if you had a static property, that would be different.

Answer 3

Both fields have been initialized using the static methods. So, in that case, all the static methods will be evaluated.
