Socket.Receive接收到数据

[zx123cvbnm]

为什么Socket.Receive接收到的数据不完成后半部分都是空的？
客户端：
_nws是一个NetworkStream对象 sendText是发送内容
_nws.Write(Encoding.Unicode.GetBytes(sendTxt), 0, Encoding.Unicode.GetBytes(sendTxt).Length);
服务器端： byte[] _packetBuff = new byte[_maxPacket];
int i=clientSkt.Receive(_packetBuff);
string Content = Encoding.Unicode.GetString(_packetBuff,0,i);//Content比sendTxt少了一大截

补充：通过测试i=Encoding.Unicode.GetBytes(sendTxt).Length
急求！！！各位帮帮忙

int i = clientSkt.Receive(_packetBuff, packetBuff.Length, 0);
string Content = Encoding.Unicode.GetString(_packetBuff,0,i);

int i = clientSkt.Receive(_packetBuff, _packetBuff.Length, 0);
string Content = Encoding.Unicode.GetString(_packetBuff,0,i);
