Problem with System.IO.Path.Combine()

[madankarmukta]

HI,
I am getting problem while combining the path "c:" and "File1.txt".The .Net's
Path.Combine('c:","File1.txt") merely returns c:File1.txt hence Path.combine(string path) always retuen false , though file exists in the drive.Can anybody tell me what may b the remeady over this?
Thanks!

perhaps adding a forward slash after 'c:' so your code should look like

System.IO.Path.Combine("C:\", "File1.txt")

right ?

Hi,
Thanks for the quick update.But How can i make it more generic..? What if in the function Path.combine(path1,path2) we are having path1 as "c:\\temp1\\" and path2 as "text.txt" then in this can concatinating the path1 with "\" won't
b the solution..?

Thanks!

Look for these methods:

String.EndsWith (String) 
String.StartsWith (String)

in your .Net documentation, and use them to check whether your string ends or begins with "\\".

It only misbehaves when you feed root directory without slash as first argument. Always has as long as I've used it. So does:

DirectoryInfo dir = new DirectoryInfo("C:")

But both of these will work:

Path.Combine(@"C:\Some Dir", "File.txt");
Path.Combine(@"C:\Some Dir\", @"File.txt");

I've always assumed it's because C: is not a valid place on the disk, the root starts at C:\ so to speak.

In the days of DOS and multiple drives, if the "current directory" on C drive was c:\temp\ and you were currently sitting in A:\install\, refering to JUST "c:" would dump you in "c:\temp\" whereas "c:\" would be just that, "c:\".
That was just the way microsoft/dos handled it's mounting system.
If you really look they're all like \{root}\bus[0]\device[0]\hda or something like that in XP.

Ohh..

Thanks everybody for much response..
I solved the problem just by concatenating path1 with "\" .Rest is taken care of by path.combine..

Thanks!
