连接错误System.Net.Sockets.SocketException：由于系统缓冲区空间不足或列队已满，不能执行套接字上的操作

使用Socket通信方式上传大文件遇到的问题，60M上传没有问题，超过60M报这个错误，是因为一般通信都是小数据量的，但如果是上传文件，那一般都是大数据量的，所以发送和接收数据的方式也有一定的不同

namespace socketServer

{

public static class FileSender

{

private const int BufferSize = 1024;

Socket sock = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);

sock.Connect(ip);

using (FileStream reader = new FileStream(path, FileMode.Open, FileAccess.Read, FileShare.None))

{

long send = 0L, length = reader.Length;

sock.Send(BitConverter.GetBytes(length));

string fileName = Path.GetFileName(path);

sock.Send(Encoding.Default.GetBytes(fileName));

Console.WriteLine("Sending file:" + fileName + ".Plz wait...");

byte[] buffer = new byte[BufferSize];

int read, sent;

//断点发送 在这里判断设置reader.Position即可

while ((read = reader.Read(buffer, 0, BufferSize)) != 0)

{

sent = 0;

while ((sent += sock.Send(buffer, sent, read, SocketFlags.None)) < read)

{

send += (long)sent;

//Console.WriteLine("Sent " + send + "/" + length + ".");//进度

}

}

Console.WriteLine("Send finish.");

using (FileStream writer = new FileStream(Path.Combine(path, fileName), FileMode.Create, FileAccess.Write, FileShare.None))

//断点接受 在这里判断设置writer.Position即可

while (receive < length)
