Remove a bit of a string before a word

Question

I have string like this:

G:\Projects\TestApp\TestWeb\Files\Upload\file.jpg

How can I remove all text before "Files" (G:\Projects\TestApp\TestWeb)? The string before files can changed, so I can't count characters and remove them after 20 characters.

Thanks for your help :)

Solution

try this

string s = oldString.Substring(oldString.IndexOf("Files"));

Thanks for Meta-Knight's comment,

if another "Files" can be in early part of the string then better would be..

string s = oldString.Substring(oldString.LastIndexOf("Files"));

This is certainly valid, but I would like to add that you want to find a unique part of the string you want to keep (g:\uploadfiles\john\Files\Upload\ would fail). You could consider .jpg or \Files\Upload\ as well. Also, suggest .tolower() so you aren't impacted by case differences.

I would use LastIndexOf instead. It would minimize the risk of errors.

@Frozzare, be careful with this, in that if there can be another "Files" in the beginning somewhere, you may want to reverse the code as my edited answer shows.

In addition to using LastIndexOf, it's also a good idea to search for "\Files\" instead of just "Files" in case you have a path like "c:\My really important Files\Pictures\Files\Adult Files\NSFW" for instance.
