在C# WinForms應(yīng)用程序中實現(xiàn)高效通信,通常涉及到以下幾個方面:
下面是一個簡單的C# WinForms應(yīng)用程序示例,使用TCP協(xié)議實現(xiàn)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);
}
}
}
在這個示例中,我們使用了TCP協(xié)議實現(xiàn)了一個簡單的客戶端和服務(wù)器之間的通信。服務(wù)器端監(jiān)聽8080端口,客戶端連接到服務(wù)器并發(fā)送消息。當(dāng)接收到消息時,會彈出一個對話框顯示接收到的消息。為了提高通信效率,我們使用了異步通信和線程池等技術(shù)。
