无法从“方法组”转换为“字符串”

using System;

public class Program
{
    public static void Main()
    {
        Action method1 = Method1;
        Action method2 = Method2;
        
        // 将方法组转换为字符串
        string method1String = method1.ToString();
        string method2String = method2.ToString();
        
        Console.WriteLine("Method1: " + method1String);
        Console.WriteLine("Method2: " + method2String);
    }
    
    public static void Method1()
    {
        Console.WriteLine("This is Method1");
    }
    
    public static void Method2()
    {
        Console.WriteLine("This is Method2");
    }
}

Method1: Program+Action
Method2: Program+Action
