Class library with some useful functions.
I got bored one day and decided to practice my C# skills, so I ended up putting every function I could think of into a class library. The original purpose of the dll was to process file I/O and strings, so the name doesn't exactly fit anymore, but there are tons of functions in this file that are fairly useful and simplified so newbies could use it without knowing much.
No documentation is really needed because it's organized and simplified. If you're using this and have any questions you can totally post here or pm me. The gdi functions and mp3 function haven't been tested, and the graphics classes aren't quite implemented yet so there's no directx or opengl, just empty classes there.
I'm open to suggestions and ideas. I'm fairly new to C# so don't flame my inefficiency.

Virus Scan:
VirusTotal - Free Online Virus, Malware and URL ScannerYou should write instructions on how to use them
Intellisense lists the parameters, but I'll write up a .txt file listing each function and it's use. Nearly 2000 lines of code though, so don't expect every function to be documented for a while. -_-
You can do proper XML documentation by doing three consecutive slashes (C#) or apostrophes (VB) and when someone brings up a function it will have the documentation in intellisense. Example from my last library:
[highlight=vb.net]
''' <summary>
''' Find the string contained between two points.
''' </summary>
''' <param name="MainStr">The string to search in.</param>
''' <param name="pt1">The first point to look for in 'MainStr'</param>
''' <param name="pt2">The second point to look for in 'MainStr'</param>
''' <param name="UseLastIndex">Decides whether or not to search for the last index of 'pt2'.
''' Optional, default False.</param>
''' <param name="StartFrom">Where to start searching for 'pt1' in the string.
''' Optional, default 0</param>
''' <returns>A 'StringResult' class, Value contains the string, EndIndex returns the index of the 2nd Point. Value will be empty if either point is not found.</returns>
''' <remarks>Hot sex.</remarks>
