编译错误 缺少：语句结束

我在vb6.0中编写一断代码，出现编译错误 缺少：语句结束的错误，代码如下：
bytesData = System.Text.Encoding.ASCII.GetBytes("name=yourName&pass=yourPass&cardnumber=yourCardNumber")
req.ContentLength = bytesData.Length
Dim postStream As Stream
postStream = req.GetRequestStream()
postStream.Write bytesData, 0, bytesData.Length 还有这里本来要有括号，有括号就出现同样的错误，只好把括号去掉了
Dim res As HttpWebResponse
res = CType(req.GetResponse(), HttpWebResponse)
Dim reader As New StreamReader(res.GetResponseStream,System.Text.Encoding.GetEncoding("GB2312")) 就这个地方有问题

怎么没人回答呀

VB.NET code

 Dim sr As New StreamReader(fileName.ToString, Encoding.GetEncoding("gb2312"))
 Dim outstrs As String = sr.ReadToEnd()
 sr.Close()
