這期內容當中小編將會給大家帶來有關怎么在C# .NET中使用Socket框架，文章內容豐富且以專業的角度為大家分析和敘述，閱讀完這篇文章希望大家可以有所收獲。
1、首先簡單講下C#中Socket的簡單使用。
第一步：服務端監聽某個端口
第二步：客戶端向服務端地址和端口發起Socket連接請求
第三步：服務端收到連接請求后創建Socket連接，并維護這個連接隊列。
第四步：客戶端和服務端已經建立雙工通信（即雙向通信），客戶端和服務端可以輕松方便的給彼此發送信息。
至于簡單使用的具體實現代碼全部被我封裝到項目中了，如果需要學習簡單的實現，可以看我的源碼，也可以自行百度，有很多的教程
2、核心，框架的使用
其實，說其為框架，可能有點牽強，因為每個人對框架都有自己的理解，但是類庫和框架又有什么本質區別呢？全部都是代碼~哈哈，扯遠了
首先，空說無憑，先放上所有的代碼：

}上面放上的是框架代碼，接下來介紹下如何使用
首先，服務端使用方式：
using Coldairarrow.Util.Sockets;
using System;
using System.Text;
namespace Console_Server
{
class Program
{
static void Main(string[] args)
{
//創建服務器對象，默認監聽本機0.0.0.0，端口12345
SocketServer server = new SocketServer(12345);
//處理從客戶端收到的消息
server.HandleRecMsg = new Action<byte[], SocketConnection, SocketServer>((bytes, client, theServer) =>
{
string msg = Encoding.UTF8.GetString(bytes);
Console.WriteLine($"收到消息:{msg}");
});
//處理服務器啟動后事件
server.HandleServerStarted = new Action<SocketServer>(theServer =>
{
Console.WriteLine("服務已啟動************");
});
//處理新的客戶端連接后的事件
server.HandleNewClientConnected = new Action<SocketServer, SocketConnection>((theServer, theCon) =>
{
Console.WriteLine($@"一個新的客戶端接入，當前連接數：{theServer.ClientList.Count}");
});
//處理客戶端連接關閉后的事件
server.HandleClientClose = new Action<SocketConnection, SocketServer>((theCon, theServer) =>
{
Console.WriteLine($@"一個客戶端關閉，當前連接數為：{theServer.ClientList.Count}");
});
//處理異常
server.HandleException = new Action<Exception>(ex =>
{
Console.WriteLine(ex.Message);
});
//服務器啟動
server.StartServer();
while (true)
{
Console.WriteLine("輸入:quit，關閉服務器");
string op = Console.ReadLine();
if (op == "quit")
break;
}
}
}
}客戶端使用方式：
using Coldairarrow.Util.Sockets;
using System;
using System.Text;
namespace Console_Client
{
class Program
{
static void Main(string[] args)
{
//創建客戶端對象，默認連接本機127.0.0.1,端口為12345
SocketClient client = new SocketClient(12345);
//綁定當收到服務器發送的消息后的處理事件
client.HandleRecMsg = new Action<byte[], SocketClient>((bytes, theClient) =>
{
string msg = Encoding.UTF8.GetString(bytes);
Console.WriteLine($"收到消息:{msg}");
});
//綁定向服務器發送消息后的處理事件
client.HandleSendMsg = new Action<byte[], SocketClient>((bytes, theClient) =>
{
string msg = Encoding.UTF8.GetString(bytes);
Console.WriteLine($"向服務器發送消息:{msg}");
});
//開始運行客戶端
client.StartClient();
while (true)
{
Console.WriteLine("輸入:quit關閉客戶端，輸入其它消息發送到服務器");
string str = Console.ReadLine();
if (str == "quit")
{
client.Close();
break;
}
else
{
client.Send(str);
}
}
}
}
}最后運行測試截圖：
