I am having fun with Console Applications and just wanted to know. What's the best way to save the current buffer of a console window for later use and provide a sort of history navigation function. I know the Diagnostics namespace provides ability to read standard output but that's only if you redirect it, so basically you will have to run process all your results in a new window which seems a little dumb.

A screen buffer is a two-dimensional array of character and color data for output in a console window. A console can have multiple screen buffers. The active screen buffer is the one that is displayed on the screen. The system creates a screen buffer whenever it creates a new console.
The size of a screen buffer is expressed in terms of a coordinate grid based on character cells. The width is the number of character cells in each row, and the height is the number of rows.
You need to read the console screen buffer.
I wrote a series of articles about accessing the Console API from .NET a few years ago. The article you're interested in is Working with Console Screen Buffers.
