I have created a VS 2008 C# program that creates a series of CSV files and then emails them. The CSV files are written to a folder and each month they get overwritten. Now they want me to archive these files each month and make the output files read-only.<br />
<br />
So I have several questions:<br />
1) What function do I use to create a new folder?<br />
2) What function do I use to move these files to this new folder?<br />
3) What function do I use to delete these files from the original folder?<br />
4) What function do I use to change the file attribute to read-only?

VS C# file and directory question

C# is an object-oriented programming language created in conjunction with Microsoft’s .NET framework. Compilation is usually done into the Microsoft Intermediate Language (MSIL), which is then JIT-compiled to native code (and cached) during execution in the Common Language Runtime (CLR).
