Changing FileNames using RegEx and Recursion
- by yeahumok
Hello
I'm trying to rename files that my program lists as having "illegal characters" for a SharePoint file importation. The illegal characters I am referring to are: ~ # % & * {} / \ | : < ? - ""
What i'm trying to do is recurse through the drive, gather up a list of filenames and then through Regular Expressions, pick out file names from a List and try to replace the invalid characters in the actual filenames themselves.
Anybody have any idea how to do this? So far i have this: (please remember, i'm a complete n00b to this stuff)
class Program
{
static void Main(string[] args)
{
string[] files = Directory.GetFiles(@"C:\Documents and Settings\bob.smith\Desktop\~Test Folder for [SharePoint] %testing", "*.*", SearchOption.AllDirectories);
foreach (string file in files)
{
Console.Write(file + "\r\n");
}
Console.WriteLine("Press any key to continue...");
Console.ReadKey(true);
string pattern = " *[\\~#%&*{}/:<>?|\"-]+ *";
string replacement = " ";
Regex regEx = new Regex(pattern);
string[] fileDrive = Directory.GetFiles(@"C:\Documents and Settings\bob.smith\Desktop\~Test Folder for [SharePoint] %testing", "*.*", SearchOption.AllDirectories);
StreamWriter sw = new StreamWriter(@"C:\Documents and Settings\bob.smith\Desktop\~Test Folder for [SharePoint] %testing\File_Renames.txt");
foreach(string fileNames in fileDrive)
{
string sanitized = regEx.Replace(fileNames, replacement);
sw.Write(sanitized + "\r\n");
}
sw.Close();
}
}
So what i need to figure out is how to recursively search for these invalid chars, replace them in the actual filename itself. Anybody have any ideas?
