Cutting String

using List<string> to store them.
There is a list of strings as shown below:

"C:\WithCreationFilter_CS\bin\Debug\hello.dll"
"C:\AAA\bin\Debug\XXX.dll"
"C:\ZZZ\bin\Debug\YYY.dll"
"C:\QQQ\XXX\YYY\bin\Debug\xxx.dll"

How to get expected output as shown below??

Expected ouput:

"hello.dll"
"XXX.dll"
"YYY.dll"
"xxx.dll"

Code:

---

string s = "C:\\WithCreationFilter_CS\\bin\\Debug\\hello.dll";

string result = s.Remove(s.LastIndexOf("\\"));

I think you meant SubString instead of Remove. Your code returns "C:\WithCreationFilter_CS\bin\Debug"

All he needs is the file name to be returned from the full path. How about trying Path.GetFileName() method? Something like this

Code:

---

string FileName = Path.GetFileName(@"C:\WithCreationFilter_CS\bin\Debug\hello.dll" );

This is the way to go as it also checks for invalid characters and other edge cases.

So complete sample could look like:

Code:

---

var paths = new List<string>
{
 "C:\WithCreationFilter_CS\bin\Debug\hello.dll",
 "C:\AAA\bin\Debug\XXX.dll" ,
 "C:\ZZZ\bin\Debug\YYY.dll" ,
 "C:\QQQ\XXX\YYY\bin\Debug\xxx.dll"
}

var fileNames = paths.Select(p => Path.GetFileName(p)).ToList();

It seems I answered this question yesterday on another forum. Don't you love cross posters? :(
