這期內(nèi)容當(dāng)中小編將會(huì)給大家?guī)碛嘘P(guān)怎么在C# .NET中使用Socket框架,文章內(nèi)容豐富且以專業(yè)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(jiǎn)單講下C#中Socket的簡(jiǎn)單使用。
第一步:服務(wù)端監(jiān)聽某個(gè)端口
第二步:客戶端向服務(wù)端地址和端口發(fā)起Socket連接請(qǐng)求
第三步:服務(wù)端收到連接請(qǐng)求后創(chuàng)建Socket連接,并維護(hù)這個(gè)連接隊(duì)列。
第四步:客戶端和服務(wù)端已經(jīng)建立雙工通信(即雙向通信),客戶端和服務(wù)端可以輕松方便的給彼此發(fā)送信息。
至于簡(jiǎn)單使用的具體實(shí)現(xiàn)代碼全部被我封裝到項(xiàng)目中了,如果需要學(xué)習(xí)簡(jiǎn)單的實(shí)現(xiàn),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(shí),說其為框架,可能有點(diǎn)牽強(qiáng),因?yàn)槊總€(gè)人對(duì)框架都有自己的理解,但是類庫和框架又有什么本質(zhì)區(qū)別呢?全部都是代碼~哈哈,扯遠(yuǎn)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(wù)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(chuàng)建服務(wù)器對(duì)象,默認(rèn)監(jiān)聽本機(jī)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($"收到消息:{msg}");
});
//處理服務(wù)器啟動(dòng)后事件
server.HandleServerStarted = new Action<SocketServer>(theServer =>
{
Console.WriteLine("服務(wù)已啟動(dòng)************");
});
//處理新的客戶端連接后的事件
server.HandleNewClientConnected = new Action<SocketServer, SocketConnection>((theServer, theCon) =>
{
Console.WriteLine($@"一個(gè)新的客戶端接入,當(dāng)前連接數(shù):{theServer.ClientList.Count}");
});
//處理客戶端連接關(guān)閉后的事件
server.HandleClientClose = new Action<SocketConnection, SocketServer>((theCon, theServer) =>
{
Console.WriteLine($@"一個(gè)客戶端關(guān)閉,當(dāng)前連接數(shù)為:{theServer.ClientList.Count}");
});
//處理異常
server.HandleException = new Action<Exception>(ex =>
{
Console.WriteLine(ex.Message);
});
//服務(wù)器啟動(dòng)
server.StartServer();
while (true)
{
Console.WriteLine("輸入:quit,關(guān)閉服務(wù)器");
string op = Console.ReadLine();
if (op == "quit")
break;
}
}
}
}客戶端使用方式:
using Coldairarrow.Util.Sockets;
using System;
using System.Text;
namespace Console_Client
{
class Program
{
static void Main(string[] args)
{
//創(chuàng)建客戶端對(duì)象,默認(rèn)連接本機(jī)127.0.0.1,端口為12345
SocketClient client = new SocketClient(12345);
//綁定當(dāng)收到服務(wù)器發(fā)送的消息后的處理事件
client.HandleRecMsg = new Action<byte[], SocketClient>((bytes, theClient) =>
{
string msg = Encoding.UTF8.GetString(bytes);
Console.WriteLine($"收到消息:{msg}");
});
//綁定向服務(wù)器發(fā)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(wù)器發(fā)送消息:{msg}");
});
//開始運(yùn)行客戶端
client.StartClient();
while (true)
{
Console.WriteLine("輸入:quit關(guān)閉客戶端,輸入其它消息發(fā)送到服務(wù)器");
string str = Console.ReadLine();
if (str == "quit")
{
client.Close();
break;
}
else
{
client.Send(str);
}
}
}
}
}最后運(yùn)行測(cè)試截圖:
