相关疑难解决方法(0)

我有一个类,其中有大约20个方法.每个人都做一些Web服务消息处理.我只需对其进行更改,并意识到这些方法中的每一个都具有完全相同的try/catch:

        try
        {
            /* *** actual processing specific to each method goes here *** */
        }
        catch (FaultException<CustomException> cfex)
        {
            // common stuff
        }
        catch (CustomException cfex)
        {
            // common stuff
        }
        catch (Exception ex)
        {
            // common stuff
        }
        finally
        {
            FinalizeServiceCall(wsBus, wsMessage, response, logProps);
        }

我的问题是; 而不是在每个方法中都有这个完全相同的try/catch块,有没有办法让它变得常见？我的想法是.NET有这样的东西TransactionScope以某种方式检测离开该块时是否发生异常.有没有我可以利用这样的东西来制作一个常见的try/catch块？还有其他想法吗？

我有以下代码,它在尝试抛出错误时给出了" 用户代码未处理的异常 ":

private static void _msgQ_RecieveCompleted(object sender, ReceiveCompletedEventArgs e)
{
    try
    {
        //queue that have received a message
        MessageQueue _mq = (MessageQueue)sender;

        //get the message off the queue
        Message _mqmsg = _mq.EndReceive(e.AsyncResult);
        throw new Exception("This is a test exception by Tim");

        //set the values back into a formatted struct 
        //now process your SQL....
        Azure_SQL _azuresql = new Azure_SQL();
        _azuresql.writeMessageToStorage((_TwitterStreamFeed)_mqmsg.Body);

        //refresh queue just in case any changes occurred (optional)
        _mq.Refresh();

        //tell MessageQueue to receive next message when it arrives
        _mq.BeginReceive(); …
