忽略 C# 中的异常

问题描述

有没有更好的方法来忽略 C# 中的异常，而不是将其放在 try catch 块中并且在 catch 中什么也不做?我发现这种语法很麻烦.对于代码块，我不能简单地标记"它，以便运行时知道要忽略哪些异常吗?

Is there a better way to ignore an exception in C# than putting it up in a try catch block and doing nothing in catch? I find this syntax to be cumbersome. For a codeblock, can't I simply "tag" it in such a way so as runtime knows which exceptions to neglect?

推荐答案

我不认为有什么技巧可以避免异常，但是你可以使用下面的代码片段:

I don't think there is a trick to avoid exception but you can use the following code snippet:

public void IgnoreExceptions(Action act)
{
   try
   {
      act.Invoke();
   }
   catch { }
}

使用方法如下:

IgnoreExceptions(() => foo());

另一种解决方案是使用 AOP(面向方面​​编程) - 有一个名为 PostSharp 的工具可以让您创建一个可以捕获特定程序集/类/方法中所有异常的属性，这更接近您要查找的内容.

Another solution is to use AOP (Aspect Oriented Programming) - there's a tool called PostSharp which enables you to create an attribute that would catch all exceptions in specific assembly/class/method, which is closer to what you're looking for.
