在C#中處理異步開發中的網絡延遲,通常需要考慮以下幾個方面:
下面是一個簡單的示例,展示了如何使用C#的async和await關鍵字處理網絡延遲:
using System;
using System.Net.Sockets;
using System.Text;
using System.Threading.Tasks;
class Program
{
static async Task Main(string[] args)
{
string host = "example.com";
int port = 80;
try
{
using (TcpClient client = new TcpClient())
{
await client.ConnectAsync(host, port);
string request = "GET / HTTP/1.1\r\nHost: " + host + "\r\n\r\n";
byte[] requestBytes = Encoding.ASCII.GetBytes(request);
await client.GetStream().WriteAsync(requestBytes, 0, requestBytes.Length);
StringBuilder response = new StringBuilder();
byte[] buffer = new byte[1024];
int bytesRead;
do
{
bytesRead = await client.GetStream().ReadAsync(buffer, 0, buffer.Length);
response.Append(Encoding.ASCII.GetString(buffer, 0, bytesRead));
} while (bytesRead > 0);
Console.WriteLine(response.ToString());
}
}
catch (Exception ex)
{
Console.WriteLine("Error: " + ex.Message);
}
}
}
在這個示例中,我們使用async和await關鍵字來異步地連接到TCP服務器并發送HTTP請求。當接收到服務器的響應時,我們將響應內容輸出到控制臺。這個示例沒有實現超時和重試機制,你可以根據需要進行擴展。
