Finding the root path from the given path

Question

If string path = "\\ProgFiles\\sampleDir\\annet.dll" I want to take "\\ProgFiles\\sampleDir" alone from the path in a seperate string variable using c#. Do I have any inbuilt option for this? I am using visual studio 2008 and .net compact framework.

string directory = Path.GetDirectoryName(path);

Be aware that there are some nuances with this method (like returning null for a root directory): check out the MSDN.

And do I have any option of retrieving sampleDir alone from path??

Take a look at the System.IO.Path class. It contains a Method "GetDirectoryName". That's what you should need.

You can use the FileInfo class to do that, just try something like this

FileInfo fi = new FileInfo("Your path here"); string dirName = fi.DirectoryName;

You could try:

String path = "C:\\ProgFiles\\SampleDir\\annet.dll"; String newPath = path.Substring(0, path.LastIndexOf("\\"));

The syntax may be a little out (i have not tested it), but definitely look up .Substring and .LastIndexOf methods on strings!

No stringparsing. The other answers point to System.IO.Path which is what you should use.

Indeed. One reason would be that the Path methods work correctly with forward slashes, too.
