C # equivalent to Java Exception.printStackTrace ()?

Question

Is there an equivalent C # method for Java Exception.printStackTrace() or do I need to write something while working through InnerExceptions?

Answer 1

Try the following:

 Console.WriteLine(ex.ToString()); 

From http://msdn.microsoft.com/en-us/library/system.exception.tostring.aspx :

The default implementation for ToString, by default, gets the class name that throws the current exception, the message, the result of the ToString call in the internal exception, and the result of the .StackTrace environment call. If any of these elements is NULL, its value is not included in the returned string.

Note that in the above code, a ToString call is not required, as there is an overload that takes System.Object and calls ToString directly.

Answer 2

I would like to add: if you want to print the stack with no exception, you can use:

 Console.WriteLine(System.Environment.StackTrace); 

Answer 3

As Drew says, simply by throwing an exception, the line does this. For example, this program:

 using System; class Test { static void Main() { try { ThrowException(); } catch (Exception e) { Console.WriteLine(e); } } static void ThrowException() { try { ThrowException2(); } catch (Exception e) { throw new Exception("Outer", e); } } static void ThrowException2() { throw new Exception("Inner"); } } 

Produces this conclusion:

 System.Exception: Outer ---> System.Exception: Inner at Test.ThrowException2() at Test.ThrowException() --- End of inner exception stack trace --- at Test.ThrowException() at Test.Main()

eun (myException.StackTrace);

Answer 5

  catch (Exception ex) { Console.WriteLine(ex.StackTrace); } 

Answer 6

Is there a C # Logging API that can take an exception as an argument and handle everything for you, like Java Log4J?

Ie, use Log4NET.

Answer 7

Also look at Log4Net ... its Log4J port on .NET.
