Exclude line numbers from text selection and more

In a diff, I often want to copy code to search in my solution or share outside of code collaborator

Ctrl+C  doesn't always register (it requires right click and copy) but also the text selection will include the line numbers, forcing me to delete them manually, here is an example 

          11433    {
          11434        bool failed = false;
          11435        while(i = 2)
          11436        {
          11437            i++;
          11438            failed = (i % 2) == 0;
          11439         }

Also it will select both side of the diff. Would want to be able to select within a single file the code.

Thanks!
