推荐答案

我认为你在这里很幸运，看来你获得代码的那个博客的作者发布了一个.NET项目...我认为这是他的代码使用WhatsApp进行演示。



在此页面上，您可以找到项目的链接：[ ^ ]。



请注意，从未知来源下载任何代码都可能危险，但如果这是一个真正的.NET解决方案，你应该能够打开源并研究它。

I think you are in luck here, it appears the author of that blog where you got the code has posted a .NET project ... I assume it's his code demonstrating using WhatsApp.

On this page you'll find the link to the project: [^].

Be aware that downloading any code from an unknown source is potentially dangerous, but if this is a real .NET solution, you should be able to open the source and study it.

请参考以下代码。

Please refer the following code.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace ExampleDelegates
{
    class Program
    {
        public delegate void ShowDelegate(string Name);
        static void Main(string[] args)
        {
            ShowDelegate DelegateObject = new ShowDelegate(ShowMethod);
            DelegateObject.Invoke("This is me.");
            Console.ReadLine();
        }

        public static void ShowMethod(string _Name)
        {
            Console.WriteLine(_Name);
        }
    }
}

如果你想使用委托创建公共委托的任何位置，并将该函数与委托匹配，并分配方法并调用方法。

If you want to use the delegate any where you create the public delegate and match the function with delegate and assign the method and invoke the method.
