[C#] TestHttpPost：测试Http的POST方法的小工具

作者：zyl910。

　　这几天在调试一个使用Http POST协议的接口。在网上找了几个Http测试工具，但感觉不太好用。于是自己用C#写了一个简单的测试工具。

一、使用介绍

　　默认是“POST”模式。在最上面的文本框中输入Url地址，然后在“Post Data”文本框中输入Post参数，再点击“Go”按钮发送请求。
　　如果想使用“GET”模式。便点击左上角的组合框，选择“GET”模式，再点击“Go”按钮发送请求。
　　当发现回应内容乱码时。点击“Response Encoding”组合框，选择合适的编码。再点击“Go”按钮重新发送请求。

二、全部代码

　　窗口的代码（FrmTestHttpPost.cs）——
