The debug window is slowing me down severely, but all I want to see from it is the last few lines. I would like to not run the debug window and send the last 5 lines of the debug window to an external text file. Can someone please show me how to do this?

C#
            StringBuilder sb = new StringBuilder();

            StringWriter sw = new StringWriter(sb);

            TextWriterTraceListener myWriter = new TextWriterTraceListener(sw);

            Debug.Listeners.Add(myWriter);
//...


            string output = string.Join("\n",
                sb.ToString().Split('\n').Reverse().Take(5).Reverse());


The last line is likely to be empty so you may want to exclude empty rows from the set of rows in the stringbuilder.

I don't see where you named and created any external file?? How do you do this??

Really!?!

I gave you gold. Writing to an external file from a string is SO common you can google it: https://msdn.microsoft.com/en-us/library/8bh11f1k.aspx

I still cannot figure out how to complete what you wrote. I don't understand why you would write something incomplete.

Because it's not my place to write your code for you. That's not what this site is about.
You really can't work out how to write text to a file? Maybe you should post a new question. Please include in the question exactly where you are stuck.

Ah, now I see: I guess you were the one who misled our inquirer to this trash:
http://www.codeproject.com/Questions/995247/Trying-to-Write-from-Debug-window-to-External-File.

Please don't get me wrong: I don't blame you, but perhaps you have to ask the inquirer what he is trying to do and why this debug window at all, why using Debug and Trace. And then I tried to answer next question, at least until this person lost patience and started to play rude:
http://www.codeproject.com/Answers/995255/Trying-to-Write-from-Debug-window-to-External-File#answer1.

Your advice to post a new question did not work :-(
