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 " ;
}

?>
