c# 文件传输

send :
string path = "E://c#//convey_file//convey_file//Form1.cs";                //要传输的文件
TcpClient client = new TcpClient();
client.Connect(IPAddress.Parse("192.168.0.52"),9999);
FileStream file = new FileStream(path,FileMode.Open,FileAccess.Read);  //注意与receive的filestream的区别
BinaryReader binaryreader = new BinaryReader(file);
byte[] b = new byte[4098];
int data;
Console.WriteLine("正在发送文件");
while ((data = binaryreader.Read(b, 0, 4098)) != 0)                 //这个注意是将文件写成流的形式
{
client.Client.Send(b,data,SocketFlags.None);           //发送文件流到目标机器
}
client.Client.Shutdown(SocketShutdown.Both);
binaryreader.Close();
file.Close();

receive:
private Socket s;

public void lis()
{
