end of string found

[tshad]

IndexOf gives you the start of the string found in another string. How do
you get the end of the string found?

I am trying to get the path of the startup:

string stemp = Application.StartupPath;

I then want to do something like:

stemp =
stemp.Substring(0,stemp.IndexOf(@"theFolder\")+Str ing.length((@"theFolder\"))
+ "afile.txt";

So that I would end up with something like:

c:\folder1\theFolder\afile.txt

I could do this by putting "theFolder" in a string and then taking the lengh
of the string in my Substring call,

var s = @"theFolder\";
stemp = stemp.Substring(0,stemp.IndexOf(s)+s.Length)) + "afile.txt";

but wanted to see if there was an easier way?

Thanks,

Tom

By adding the length of the search string, which is known.

stemp.Substring(0,stemp.IndexOf(@"theFolder\")+St ring.length((@"theFolder\"))
+ "afile.txt";

There is for this type of task, use the methods of the Path class:
(add a "using System.IO;")

string stemp = Application.StartupPath;

string newFileName =
Path.Combine(Path.GetDirectoryName(stemp), "afile.txt");

Hi,

For working with files and folder you have a couple of classes like
Path , Directory and File
in your case Path.GetDirectoryName is what you are after I think
