1.Get请求

string
      strURL 
     =
      
     "
     http://localhost/WinformSubmit.php?tel=11111&name=张三
     "
     ;
System.Net.HttpWebRequest request;

     //
      创建一个HTTP请求
     

     request 
     =
      (System.Net.HttpWebRequest)WebRequest.Create(strURL);

     //
     request.Method="get";
     

     System.Net.HttpWebResponse response;
response 
     =
      (System.Net.HttpWebResponse)request.GetResponse();
System.IO.StreamReader myreader 
     =
      
     new
      System.IO.StreamReader(response.GetResponseStream(), Encoding.UTF8);

     string
      responseText 
     =
      myreader.ReadToEnd();
myreader.Close();
MessageBox.Show(responseText);
          

2.Post请求

string
      strURL 
     =
      
     "
     http://localhost/WinformSubmit.php
     "
     ;
System.Net.HttpWebRequest request;
request 
     =
      (System.Net.HttpWebRequest)WebRequest.Create(strURL);

     //
     Post请求方式
     

     request.Method 
     =
      
     "
     POST
     "
     ;

     //
      内容类型
     

     request.ContentType 
     =
      
     "
     application/x-www-form-urlencoded
     "
     ;

     //
      参数经过URL编码
     

     string
      paraUrlCoded 
     =
      System.Web.HttpUtility.UrlEncode(
     "
     keyword
     "
     );
paraUrlCoded 
     +=
      
     "
     =
     "
      
     +
      System.Web.HttpUtility.UrlEncode(
     "
     多月
     "
     );

     byte
     [] payload;

     //
     将URL编码后的字符串转化为字节
     

     payload 
     =
      System.Text.Encoding.UTF8.GetBytes(paraUrlCoded);

     //
     设置请求的 ContentLength 
     

     request.ContentLength 
     =
      payload.Length;

     //
     获得请 求流
     

     System.IO.Stream writer 
     =
      request.GetRequestStream();

     //
     将请求参数写入流
     

     writer.Write(payload, 
     0
     , payload.Length);

     //
      关闭请求流
     

     writer.Close();
System.Net.HttpWebResponse response;

     //
      获得响应流
     

     response 
     =
      (System.Net.HttpWebResponse)request.GetResponse();
System.IO.StreamReader myreader 
     =
      
     new
      System.IO.StreamReader(response.GetResponseStream(), Encoding.UTF8);

     string
      responseText 
     =
      myreader.ReadToEnd();
myreader.Close();
MessageBox.Show(responseText);
          

注：System.Web.HttpUtility.UrlEncode("多月"); 需要引用 System.web.dll

WinformSubmit.php 代码如下：

<?
     php 

    
     header
     (
     "
     content-Type: text/html; charset=Utf-8
     "
     ); 
    
     echo
      mb_convert_encoding(
     "
     123abc娃哈哈
     "
     ,
      
     "
     UTF-8
     "
     ,
      
     "
     GBK
     "
     ); 
    
    
     echo
      
     "
     \n------\n
     "
     ;
    
    
     foreach
     (
     $_POST
      
     as
      
     $key
      
     =>
      
     $value
     ){
    
     echo
      
     $key
      
     .
      
     '
     --
     '
      
     .
     $value
      
     .
     "
     \n
     "
     ;    
    }
    
    
     echo
      
     "
     \n-------\n
     "
     ;

    
     foreach
     (
     $_GET
      
     as
      
     $key
      
     =>
      
     $value
     ){
    
     echo
      
     $key
      
     .
      
     '
     --
     '
      
     .
     $value
      
     .
     "
     \n
     "
     ;    
    }
