如何用 C# 编写重试逻辑?
csharpserver side programmingprogramming更新于 2025/6/28 1:07:17
每当操作失败时都会执行重试逻辑。仅在了解失败操作的完整上下文的情况下才执行重试逻辑。
记录所有导致重试的连接故障非常重要，这样才能识别应用程序、服务或资源的根本问题。
示例
class Program{
public static void Main(){
HttpClient client = new HttpClient();
dynamic res = null;
var retryAttempts = 3;
var delay = TimeSpan.FromSeconds(2);
RetryHelper.Retry(retryAttempts, delay, () =>{
res = client.GetAsync("https://example22.com/api/cycles/1");
});
Console.ReadLine();
}
}
public static class RetryHelper{
public static void Retry(int times, TimeSpan delay, Action operation){
var attempts = 0;
do{
try{
attempts++;
System.Console.WriteLine(attempts);
operation();
break;
}
catch (Exception ex){
if (attempts == times)
throw;
Task.Delay(delay).Wait();
}
} while (true);
}
}
