c#利用webclient类库发送WEB请求时，乱码

[dujunli]

我利用c#提供的类库webclient采用POST方式向另一台运行PHP的WEB服务器发送WEB请求，但是接收到的却是乱码！
我想可能是C#采用的是UNICODE的编码方式，怎么将UNICODE转为GBK编码方式？

Public Shared Function GetDate(ByVal strUrl As String) As String
Dim html As String = ""

Dim resp As HttpWebResponse
Dim req As HttpWebRequest = CType(HttpWebRequest.Create(strUrl), HttpWebRequest)
req.Timeout = 15000
resp = CType(req.GetResponse(), HttpWebResponse)
Dim sr As StreamReader = New StreamReader(resp.GetResponseStream(), System.Text.Encoding.Default)
html = sr.ReadToEnd()

Return html
End Function

Dim sr As StreamReader = New StreamReader(resp.GetResponseStream(), System.Text.Encoding.Default)

把你的POST数据先用HttpUtility.UrlEncode转换

string s = "abc=" + HttpUtility.UrlEncode("转换", System.Text.Encoding.Default);

or

string s = "abc=" + HttpUtility.UrlEncode("转换", System.Text.Encoding.GetEncoding("GB2312"));
