有没有人知道.Net异常类型的列表。 ArgumentNullException 在什么情况下你应该使用它们？目前我只是根据类型名称猜测，但我宁愿得到正确的。

As在这种情况下，这取决于大多数时间他们的名字和论据是有意义的。例如，当检查null值的方法/构造函数参数时，通常会使用ArgumentNullException 。

然后你有其他人例如 FileNotFoundException ， NullReferenceException ， InvalidOperationException 看到他们阅读非常容易，应该常识地使用。

更新1：，有人建议，他们也在MSDN上： / p>

更新2：关于使用情况，Microsoft已为保留的异常类型指定： / p>

Does anyone know of a list of .Net Exception types .e.g. ArgumentNullException and under what circumstances you should use them? At the moment I'm just guessing based on the type name but I would rather get it right.

A list of them:

As for the circumstance, it depends, most of the time they make sense based on their name and arguments. ArgumentNullException, for example, is usually used when checking method / constructor arguments for null values.

Then you have others such as FileNotFoundException, NullReferenceException, InvalidOperationException, as you can see they read very easily and should be used with common sense.

Update 1: as someone has suggested, they are also on MSDN:

Here are views on common exceptions available:

Update 2: as for usage, Microsoft has guidelines for reserved exception types:
