C# - 从类内部调用方法

public class MyClass
{
    public void MyMethod()
    {
        Console.WriteLine("Hello, World!");
    }
}

public class Program
{
    public static void Main(string[] args)
    {
        MyClass myClass = new MyClass();
        myClass.MyMethod();
    }
}

public class MyClass
{
    public static void MyMethod()
    {
        Console.WriteLine("Hello, World!");
    }
}

public class Program
{
    public static void Main(string[] args)
    {
        MyClass.MyMethod();
    }
}

public class MyClass
{
    public void MyMethod()
    {
        Action myAction = delegate()
        {
            Console.WriteLine("Hello, World!");
        };
        myAction();
    }
}

public class MyClass
{
    public void MyMethod()
    {
        Action myAction = () => Console.WriteLine("Hello, World!");
        myAction();
    }
}
