How to recognize a path inside a string

Question

Just that... I get a string which contains a path to a file plus some arguments. How can I recognize the path? I thought about the index of the '.' in the file... but I don't like it.
What about using regular expressions? Can anyone point me in the right direction?

Regards

Edit: Theses are valid entries...
somefile.msi /a
C:\MyFolder\SomeFile.exe -i -d

I don't care much about the arguments cause once I have the path I'll assume the rest are arguments

You can use System.IO.Path, and it's static methods.

bool isPath = System.IO.Path.GetDirectoryName(@"C:\MyFolder\SomeFile.exe -i -d") != String.Empty;
if (isPath)
{
    Console.WriteLine("The string contains a path");
}

The static Path class has several other methods which are useful as well, like .GetFilename, .GetExtension and .GetPathRoot.

You can also probably use System.IO.Directory and System.IO.File for additional features.
