pretty printing exceptions in C#

Question

Is there any API that allows to prints all the exception-related info (stack trace, inner etc...)? Just like when the exception is thrown - all the data is printed to the standard output - is there any dedicated method that does it all?

thanks

`Console.WriteLine("Error: {0}", ex.ToString());` not printing the exception – Moeez May 19 '20 at 05:33

How pretty the result will be?! – Mehdi Dehghani Jul 26 '20 at 15:34
It will be very pretty! – jgauffin Jul 27 '20 at 07:20
Console.WriteLine() will auto _ToString()_ on it, and it is ugly still, very hard to see. Sometimes _ex.Message_ is good enough without blowing out too much details – A. Go Dec 17 '20 at 09:10

the ToString method of Exception does exactly that.

Are there any recommendations how to format things when overriding ToString, e.g. on e.g. a DisposersFailedException which may contain multiple exceptions if multiple exceptions were thrown in the course of disposing an object? – supercat Dec 15 '10 at 21:52

For printing exceptions in C#, you can use Debug.WriteLine():

    try
    {
        reader = cmd.ExecuteReader();
    }
    catch (Exception ex)
    {
        Debug.WriteLine("<<< catch : "+ ex.ToString());
    }

Also, you can use this for other exceptions, for example with MySqlException:

   try
    {
        reader = cmd.ExecuteReader();
    }
    catch (MySqlException ex)
    {
        Debug.WriteLine("<<< catch : "+ ex.ToString());            
    }

But, if you need printing a Exception's Message, you have to use Message:

    try
    {
        reader = cmd.ExecuteReader();
    }
    catch (MySqlException ex)
    {
        Debug.WriteLine("<<< catch : "+ ex.Message);            
    }
