在C# WinForms应用程序中实现高效通信,通常涉及到以下几个方面:
下面是一个简单的C# WinForms应用程序示例,使用TCP协议实现高效通信:
using System;
using System.Net;
using System.Net.Sockets;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
namespace WinFormsApp
{
public partial class MainForm : Form
{
private TcpClient _client;
private NetworkStream _stream;
private StringBuilder _receiveBuffer = new StringBuilder();
public MainForm()
{
InitializeComponent();
}
private async void btnConnect_Click(object sender, EventArgs e)
{
_client = new TcpClient();
await _client.ConnectAsync("localhost", 8080);
_stream = _client.GetStream();
btnSend.Enabled = true;
}
private async void btnSend_Click(object sender, EventArgs e)
{
string message = txtMessage.Text;
byte[] data = Encoding.UTF8.GetBytes(message);
await _stream.WriteAsync(data, 0, data.Length);
}
private async void OnDataReceived(object sender, NetworkStreamEventArgs e)
{
byte[] buffer = new byte[1024];
int bytesRead = await _stream.ReadAsync(buffer, 0, buffer.Length);
_receiveBuffer.Append(Encoding.UTF8.GetString(buffer, 0, bytesRead));
string receivedMessage = _receiveBuffer.ToString();
MessageBox.Show(receivedMessage);
}
protected override void OnFormClosing(FormClosingEventArgs e)
{
if (_client != null)
{
_client.Close();
}
base.OnFormClosing(e);
}
}
}
在这个示例中,我们使用了TCP协议实现了一个简单的客户端和服务器之间的通信。服务器端监听8080端口,客户端连接到服务器并发送消息。当接收到消息时,会弹出一个对话框显示接收到的消息。为了提高通信效率,我们使用了异步通信和线程池等技术。
