服务器端：
是c++写的执行sql语句从oracle数据库中查询内容通过socket发送;c++编译默认编码是unicode
_RecordsetPtr Rp=connect.GetRecordset(sql);
_variant_t varUserName;
string strUserName;
varUserName = Rp->GetCollect ("TICKETCODE");//票号
strUserName=strUserName+(char *)_bstr_t(varUserName);
strUserName=rtrim(strUserName);
send(clientSocket,strUserName.c_str(),strUserName.length(),0);
客户端：
是c#写的WP客户端接收以后乱码 相关代码如下;[（c++写的windows窗体应用程序客户端接收不会乱码;）/size]
string response = "something";
SocketAsyncEventArgs socketEventArg = new SocketAsyncEventArgs();
socketEventArg.RemoteEndPoint = _socket.RemoteEndPoint;
socketEventArg.SetBuffer(new Byte[MAX_BUFFER_SIZE], 0, MAX_BUFFER_SIZE);
socketEventArg.Completed += new EventHandler<SocketAsyncEventArgs>(delegate(object s, SocketAsyncEventArgs e)
response = Encoding.UTF8.GetString(e.Buffer, e.Offset, e.BytesTransferred);//个人猜测是这里设置编码有问题
response = response.Trim('\0');
[size=16px]改成如下代码也不行
response = Encoding.unicode.GetString(e.Buffer, e.Offset, e.BytesTransferred);
求助啊啊啊
------解决方案--------------------
c++那边就用普通的字符集，可以考虑发送之前转码
或在 WP 端接收到后进行转码
