C# 有try-catch ,但是没有retry 功能，通过用有限次循环的办法来模拟Retry，当然中间需要加一个等待的过程。

我们可以利用C#的匿名方法(anonymous methods)和匿名委托(anonymous delegate)修饰此功能

using System;using System.Collections.Generic;using System.Linq;using System.Text;using System.Threading;namespace Exchange.Common{    public class ActionExecutor    {        /// 
        ///         /// 
        /// 
                 ///         ///         ///         ///         ///         ///         public static void Excute
         
          (Action
          
            action, T1 arg1, string customerName, string actionName, string poNumber, int retryCount = 3)        {            Excute
           
            (action, arg1, customerName, actionName, poNumber, new TimeSpan(0, 0, 3));        }        /// 
            
        /// 重试一个参数带返回值        /// 
        /// 
            
             参数类型1
                    /// 
            
             返回类型
                    /// 
            执行的方法        /// 
            参数1        /// 
            重试间隔        /// 
            重试次数        /// 
            
             返回类型T
                    public static void Excute
            
             (Action
             
               action, T1 arg1,string  customerName,string actionName, string poNumber, TimeSpan retryInterval, int retryCount = 3)        {            //var exceptions = new List
              
               (); for (int retry = 0; retry < retryCount; retry++) { try { action(arg1); return; } catch (Exception ex) { ExceptionHandler.Do(string.Format("{0} {1} \"{2}\" error", customerName, actionName, poNumber, retry), ex); //exceptions.Add(ex); Thread.Sleep(retryInterval); } } } }}
              
             
            
           
          
         

 

在其他类中调用

ActionExecutor.Excute(RequesetOrder, order,                                        CUSTOMER_NAME,                                                "request order detail", order.OrderNumber);//RequesetOrder 类方法//order 是RequesetOrder的参数
