引用方法和异常类（C＃、. net）

Question

I have a class with a method and I want to throw an exception within the method. In this I would like to reference the method and class in which the exception was thrown to find the source of the error more easily.

public class SomeClass
{
    public void SomeMethod()
    {
        (..)
        Throw new Exception("An error occurred. Method:" + ?? + ", Class:" + ?? +");
    }

Answer 1

You dont need to do that. Look at the StackTrace property of the exception in your try-catch block.

Answer 2

That information will already be in the stack trace. There's no need to include it in the message as well.

If you absolutely have to, there's MethodBase.GetCurrentMethod() . For the class, would you want the class of the execution-time object on which the method was called, or the method which is actually executing? (I would stick to the stack trace though...)

Answer 3

You actually already have all that information and just need to access it via the Exception's StackTrace property with something like:

        try
        {
            // to do something exceptional
        }
        catch (Exception ex)
        {
            Console.WriteLine(ex.StackTrace);
        }

This sample just write to std out but you could do anything with the StackTrace information you want, including logging it to file or db.

Answer 4

您实际上可以为此使用StackTrace类。
