C#忽略异常 [英] Ignore Exception in C#
问题描述
在 C# 中,是否有比将异常放在 try catch 块中而在 catch 中什么都不做更好的方法来忽略异常?我发现这种语法很麻烦.对于代码块,我不能简单地以这样的方式标记"它,以便运行时知道要忽略哪些异常?
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
我认为没有避免异常的技巧,但您可以使用以下代码片段:
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(面向方面的编程) - 有一个名为 PostSharp 的工具,它使您能够创建一个属性来捕获特定程序集/类/方法中的所有异常,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.
