先把流转换为字节数组

using (MemoryStream memstream = new MemoryStream())

byte[] buffer = new byte[];
while ((bytesRead = sOut.BaseStream.Read(buffer, , buffer.Length)) > )
{
memstream.Write(buffer, , bytesRead);
}
bytes = memstream.ToArray();
memstream.Close();
}
再把字节数组以指定编码转为字符串
var out_str = System.Text.Encoding.UTF8.GetString(bytes);
