The following example retrieves the full path of the specified file.

string fileName = @"C:\TMP\log.txt";
FileInfo fileInfo = new FileInfo(fileName);
if (!fileInfo.Exists)
{
 return;
}

Console.WriteLine("{0} has a directoryName of {1}",
 fileName, fileInfo.DirectoryName);
/* This code produces output similar to the following,
 * though actual results may vary by machine:
 *
 * C:\TMP\log.txt has a directory name of C:\TMP
 */
