Where to find information on exceptions thrown by classes and methods?

Question

I am trying to add more specific error handling to my c# app, but I am finding it hard to track down what exceptions are thrown by classes and method. Is there a way through visual studio 2010 to find this info, or maybe an exception list?

Answer 1

Just find the class/method you are interested in on MSDN.

For example, look at this page for the Dictionary.Remove Method . If the method throws an Exception (like this one), you can get the information for the Exceptions section of the page.

Answer 2

If you are talking about .Net framework methods, they are documented in the hover over help. You will see Exceptions: . Or you can see it in the object browser Ctrl+W, J as well. Or press F1 over a function to go to MSDN help, where they are documented in detail.

Answer 3

如果您允许抛出异常，则应该能够在“管理工具”的“事件查看器”中查看异常详细信息。

Answer 4

You can find specific uses of a particular exception, but there is no complete listing of all exceptions any method might throw.

Consider the following method:

  public void SomeMethod()
  {
       SomeObject x = null;
       x.SomeMethod(); // NullReferenceException

       File.Open("SomePath", FileMode.CreateNew); // Any number of File Exceptions potentially

       throw new CustomException();
  };

How would a code analyzer be able to determine which potential exceptions there were?

If you're looking for information on a specific class, I'd check the documentation for it.
