script to rename files in ASP.NET C#

[calibunny]

We are trying to move files to SharePoint but need to rename them first since many have invalid characters. A previous developer started the script below. Any suggestions on how to adept it to check for valid file names and then rename the invalid files?

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.IO;
using Microsoft.SharePoint;
using System.Data.SqlClient;
using System.Threading;

namespace SPMoveFiles
{    class Program
    {
        private static string site, web, list, problem;
        private static SPSite mySite;
        private static SPWeb myWeb;
        static void Main(string[] args)
        {          
            Console.WriteLine("Enter the directory of the files you would like to migrate.");
            string filePath = Console.ReadLine();
            
        RenameFiles(filePath);          
        }

        //This method needs to be changed.
        private static void RenameFiles(string filePath){
            string[] files = Directory.GetFiles(filePath);
            foreach (string fileName in files)
            {
                  //Concatenate the file to 20 characters.
                //Replace invalid characters with an underscore.               
            }
            string[] dirs = Directory.GetDirectories(filePath);
            foreach (string dirName in dirs)
            {
                
                //Here, if the directory is greater than 20 characters, we must concatenate it to 20 characters.
}
}
return result;}
}
}

Thanks for any assistance,
Cali

try looking into the FileInfo class. It's in the System.IO Namespace

TIP: When you first created your question you were asked to wrap your code with [code] tags.

It really does help a bunch. Look how much easier it is to read now that someone has done it for you. Its the button with a '#' on it. More on tags. They're cool. Check'em out.

So your questions is "How do I rename a file?"
System.Files.Mo ve(oldname, newname)
It's weird, but it is Windows. If you move it from a folder, into the same folder with a new name, that is a re-rename.

Not only windows AFAIK in Linux too, and Unix
