c# Socket怎样才可以把数据接收完整啊？

我现在是这样做的，但经常收不完整。
public string GetSocket(string str)
{
try
{
IPEndPoint ipEndPoint = new IPEndPoint(IPAddress.Parse(db.server), serverPort);
client = new Socket(ipEndPoint.AddressFamily, SocketType.Stream, ProtocolType.Tcp);
client.Connect(ipEndPoint);
string sendStr = str;
byte[] bs = Encoding.Unicode.GetBytes(sendStr);
SendData(bs, client);
recvStr = "";
byte[] recvBytes = new byte[15000000];
int bytes;
bytes = client.Receive(recvBytes, recvBytes.Length, 0);//从服务器端接受返回信息
recvStr += Encoding.Unicode.GetString(recvBytes, 0, bytes);

//client.BeginReceive(dataBuffer, 0, dataBuffer.Length, SocketFlags.None, new AsyncCallback(RecieveCallBack), client);
//receiveDone.WaitOne();

client.Close();
return recvStr;
//return response;
}
catch
{
return "";
}

}

、、、这样，Receive的返回值是接收的字节数，当是0时表示传送结束，否则循环接收
缓冲区不用太大，8k或64k看情况
Byte[] RecvBytes = new Byte[1024*8];
int iBytes = 1;
string strAllHtml = "";
while (iBytes > 0)
{
iBytes = conn.Receive(RecvBytes, RecvBytes.Length, 0);
strAllHtml += Encoding.UTF8.GetString(RecvBytes, 0, iBytes);
}
