c# - Console.WriteLine slow

Question

I run through millions of records and sometimes I have to debug using Console.WriteLine to see what is going on.

However, Console.WriteLine is very slow, considerably slower than writing to a file.

BUT it is very convenient - does anyone know of a way to speed it up?

Answer 1

If it is just for debugging purposes you should use Debug.WriteLine instead. This will most likely be a bit faster than using Console.WriteLine.

Example

Debug.WriteLine("There was an error processing the data.");
