高手请指点HttpWebRequest乱码问题！急啊~

[大川川-]

我在向站点发送请求时，只要有中文就乱码！
string strData = "";

Encoding encoding = Encoding.GetEncoding("GB2312");
byte[] data = encoding.GetBytes( strPostData );

// 准备请求...
try
{
HttpWebRequest myRequest = (HttpWebRequest)WebRequest.Create(strUrl);
myRequest.Method = "POST";
myRequest.Timeout = 60000;
myRequest.ContentType = "application/x-www-form-urlencoded";
myRequest.ContentLength = data.Length;
Stream newStream = myRequest.GetRequestStream();

// 发送数据
newStream.Write(data, 0, data.Length);
newStream.Close();

//得到网页的原文件
HttpWebResponse response = ( HttpWebResponse )myRequest.GetResponse();
Stream resStream = response.GetResponseStream();
StreamReader sr = new StreamReader( resStream, System.Text.Encoding.UTF8 );
strData = sr.ReadToEnd();
resStream.Close();
sr.Close();
response.Close();

}
catch ( Exception ex )
{
Response.Write( ex.Message );
}
return strData ;

StreamReader sr = new StreamReader( resStream, System.Text.Encoding.UTF8 );
这里也得把编码改一下

[大川川-]

strPostData 中有中文就变成Áõ

我已经把UTF8 改为 System.Text.Encoding.Default
还是不行！
急啊，老大们帮忙啊！！！！！！！！！11

[孟子E章]

先看看原来的是什么编码

[大川川-]

chenguang79(小虫)
我把resStream, System.Text.Encoding.UTF8 改为什么?
谢谢!

[大川川-]

孟子老大来了!我是直接从页面取来的数据！

[大川川-]

提交数据<lastname>先生</lastname><firstname>刘</firstname>
返回数据 <firstname>Áõ</firstname><lastname>ÏÈÉú</lastname>
高人吃饭时帮小弟看看阿！

[sanniko]

先分析好你请求的页面用的什么编码。然后用上面写的收数据的方法看下

[greatbag]

StreamReader sr = new StreamReader( resStream, encoding);试试

[feisunsunnys]

myRequest.ContentType = "application/x-www-form-urlencoded;charset=utf-8";
改这，加个charset=utf-8
