1. 安装BytesIO程序包
1、点击工程项目,然后右键,选择“管理NuGet程序包”,如下: 2、出现如下界面,然后在搜索框输入BytesIO,然后安装下面的BytesIO.TCP的程序包。 注意BytesIO.TCP是依赖.NET框架4.5以上的版本的,所以创建工程的时候要选择高点的版本。
2. 做一个简单的界面
程序界面如下,做得比较丑。 其中Host IP是远程主机IP,Host Port是远程主机端口号。
3. 各控件相关代码
3.1 public Form()窗体构造函数代码
在Form()函数中,主要做了生成窗体时,获取了本机所有网卡的IP地址,然后预设了一些控件的默认值。最后还监听了一些tcp client相关的事件,代码如下:
public Form1()
{
InitializeComponent();
CheckForIllegalCrossThreadCalls = false;
string strHostIP = Dns.GetHostName();
IPAddress[] ipadrlist = Dns.GetHostAddresses(strHostIP);
foreach (IPAddress ipaddr in ipadrlist)
{
if (ipaddr.AddressFamily == System.Net.Sockets.AddressFamily.InterNetwork)
cbbHostIP.Items.Add(ipaddr.ToString());
}
cbbHostIP.Items.Add("127.0.0.1");
cbbHostIP.SelectedIndex = 0;
tbHostPort.Text = "8080";
client.OnDataReceived += Client_OnDataReceived;
client.OnConnectedSuccessfully += Client_OnConnectedSuccessfully;
client.OnDisconnected += Client_OnDisconnected;
}
3.2 请求连接按钮点击事件
在界面上输入远程主机IP和对应的远程主机端口后,点击一下按钮,就会去连接这个服务端了,点击事件函数如下:
private void btnConnect_Click(object sender, EventArgs e)
{
if (client.IsConnected == false)
{
client.Host = cbbHostIP.Text;
client.Port = int.Parse(tbHostPort.Text);
client.Connect();
}
else
{
client.Disconnect();
}
}
IsConnected属性是BytesIO.TCP程序包自带的一个属性,我们可以通过这个属性判断当前是否已经连接了,如果没有连接那么点击一下,就调用 client.Connect(); 函数进行连接即可。

}
