C＃异常在同一个try / catch块中处理两次 [英] C# Exception being handled twice in same try/catch block

问题描述

您好

我有一个异常问题，正在处理两次。

I have an exception issue which is being handled twice.

在try块中，它抛出一个HttpAntiForgeryException它被第一次捕获" HttpAntiForgeryException "捕获，它被重新抛出。

Within the try block, it is throwing a HttpAntiForgeryException, and it is being caught by the first catch "HttpAntiForgeryException", where it is being re-thrown.

然而，它正被捕获第二次捕获"例外"作为"未处理的异常"，以及它再次被抛出的地方。

However, it is being caught by the second catch "Exception" as an "unhandled exception", and where it is being thrown again.

try
{
// Code throwing HttpAntiForgeryException
}
catch (HttpAntiForgeryException ex)
{
	throw;
}
catch (Exception ex)
{
	throw new CustomUnexpectedException(message: "BaseController.OnAuthorization", innerException: ex);
}

如何避免这种情况？

谢谢

推荐答案

也许是这样。

try
{
// Code throwing HttpAntiForgeryException
}
catch (Exception ex)
{
   if(ex is HttpAntiForgeryException)
      throw;
   else
      throw new CustomUnexpectedException(message: "BaseController.OnAuthorization", innerException: ex);
}
