用socket写了一个一个客户端和服务端，但是客户端连接不上，报10060错误，求解

用socket写了一个一个客户端和服务端，但是客户端连接不上，报10060错误，求解，服务器端代码如下：
#define _WINSOCK_DEPRECATED_NO_WARNINGS
#include
#include <Winsock2.h>
#pragma comment(lib, "ws2_32.lib")
#include <WS2tcpip.h>
#include
#include <windows.h>

using namespace std;

SOCKADDR_IN ClientAddr = { 0 };
int ClientAddrLen = sizeof(ClientAddr);
SOCKET ClientSocket[1001];

//DWORD WINAPI InstantChat(LPVOID n);

void InstantChat(int n)
{
char Buff[1024] = { 0 };
int ret = 0;

while (1)
{
	ret = recv(ClientSocket[n], Buff, sizeof(Buff), NULL);
	if (ret > 0)
	{
		cout << inet_ntoa(ClientAddr.sin_addr) << "发来的消息：" << Buff;
		Buff[ret] = 0;
	}
}

}

int main(void)
{
SOCKET ServerSocketFd = 0;
int ret = 0;
sockaddr_in ServerAddr = { 0 };

WSADATA WsaData;
WSAStartup(MAKEWORD(1, 1), &WsaData);

if ((LOBYTE(WsaData.wVersion) != 1) || (HIBYTE(WsaData.wVersion) != 1))
{
	cout << "Socket版本确认失败" << endl;
	return -1;
}
cout << "Socket版本确认成功" << endl;

//ServerSocketFd = socket(AF_INET, SOCK_STREAM, IPPROTO_TCP);
ServerSocketFd = socket(AF_INET, SOCK_STREAM, 0);
if (-1 == ServerSocketFd)
{
	cout << "创建SOCKET套接字失败" << endl;
	WSACleanup();
	return -1;
}
cout << "socket套接字创建成功" << endl;

ServerAddr.sin_family = AF_INET;
ServerAddr.sin_addr.S_un.S_addr = htonl(INADDR_ANY);
ServerAddr.sin_port = htons(6000);
//ServerAddr.sin_addr.S_un.S_addr = inet_addr("192.168.31.100");
//inet_pton(AF_INET, "192.168.31.100", (void *)&ServerAddr.sin_addr.S_un.S_addr);

ret = bind(ServerSocketFd, (SOCKADDR *)&ServerAddr, sizeof(ServerAddr));
if (0 != ret)
{
	cout << "bind绑定失败" << GetLastError() << endl;
	closesocket(ServerSocketFd);
	WSACleanup();
	return -1;
}
cout << "bind绑定成功" << endl;

ret = listen(ServerSocketFd, 10);
if (0 != ret)
{
	cout << "listen监听失败" << GetLastError() << endl;
	closesocket(ServerSocketFd);
	WSACleanup();
	return -1;
}
cout << "listen监听成功" << endl;

for (int i = 0; i < 1001; i++)
{
	ClientSocket[i] = accept(ServerSocketFd, (SOCKADDR *)&ClientAddr, &ClientAddrLen);
	if (-1 == ClientSocket[i])
	{
		cout << "客户端连接失败" << GetLastError() << endl;
		closesocket(ServerSocketFd);
		WSACleanup();
		return -1;
	}
	cout << "客户端连接成功" << endl;

	CreateThread(NULL, NULL, (LPTHREAD_START_ROUTINE)InstantChat, (LPVOID)i, NULL, NULL);

}

closesocket(ServerSocketFd);

WSACleanup();

while (1);

system("pause");

return 0;

}

客户端的代码如下：
#define _WINSOCK_DEPRECATED_NO_WARNINGS
#include
#include <Winsock2.h>
#include <WS2tcpip.h>
#pragma comment (lib, "ws2_32.lib")
#include
#include <windows.h>

using namespace std;

int main(void)
{
SOCKET ClientSocketFd = 0;
SOCKADDR_IN ClientAddr = { 0 };
int ret;
char Buff[1024] = { 0 };

WSADATA WsaData;
WSAStartup(MAKEWORD(1, 1), &WsaData);
if ((LOBYTE(WsaData.wVersion) != 1) || (HIBYTE(WsaData.wVersion) != 1))
{
	cout << "确认版本失败" << endl;
	return -1;
}
cout << "确认版本成功" << endl;

//ClientSocketFd = socket(AF_INET, SOCK_STREAM, IPPROTO_TCP);
ClientSocketFd = socket(AF_INET, SOCK_STREAM, 0);
if (-1 == ClientSocketFd)
{
	cout << "socket创建失败" << GetLastError() << endl;
	WSACleanup();
	return -1;
}
cout << "socket创建成功" << endl;

ClientAddr.sin_family = AF_INET;
ClientAddr.sin_addr.S_un.S_addr = inet_addr("172.0.0.1");
ClientAddr.sin_port = htons(6000);
//inet_pton(AF_INET, "172.0.0.1", (void *)&ClientAddr.sin_addr.S_un.S_addr);

ret = connect(ClientSocketFd, (SOCKADDR *)&ClientAddr, sizeof(ClientAddr));
if (-1 == ret)
{
	cout << "客户端连接失败" << GetLastError() << endl;
	closesocket(ClientSocketFd);
	WSACleanup();
	return -1;
}
cout << "客户端连接成功" << endl;

while (1)
{
	cin >> Buff;
	send(ClientSocketFd, Buff, sizeof(Buff), NULL);
}

closesocket(ClientSocketFd);

WSACleanup();

while (1);

system("pause");
return 0;

}

运行结果：

求高手指点一下
