本文介绍了一个使用C#实现的WebSocket服务器示例，该服务器能够接收客户端消息，并通过调用外部DLL进行处理后再发送回客户端。文章展示了如何配置服务器监听、处理连接事件及消息，并详细解释了与DLL交互的过程。

[DllImport(@"XXX.dll", CallingConvention = CallingConvention.StdCall)]
public static extern int XXX(string strin,StringBuilder strout);

FleckLog.Level = LogLevel.Debug;
var allSockets = new List<IWebSocketConnection>();
var server = new WebSocketServer("ws://0.0.0.0:8181");
server.Start(socket =>
{
socket.OnOpen = () =>
{
Console.WriteLine("Open!");
allSockets.Add(socket);
};
socket.OnClose = () =>
{
Console.WriteLine("Close!");
allSockets.Remove(socket);

socket.OnMessage = message =>
{
Console.WriteLine(message);
message = getDate(message);
socket.Send(message);
};
});

var input = Console.ReadLine();
while (input != "exit")
{
input = Console.ReadLine();
}

}

private static string getData(string message)
{
StringBuilder response = new StringBuilder();
response.Capacity = 100;//设置字符串最大长度

var aa = XXX(message, response);
var result = response.ToString();

if (result.Substring(0, 2) != "00")
{
result = "获取失败";
}
return result;
}
