Get full path without filename from path that includes filename

Question

Is there anything built into System.IO.Path that gives me just the filepath?

For example, if I have a string

@\"c:\

Answer 1

I used this and it works well:

string[] filePaths = Directory.GetFiles(Path.GetDirectoryName(dialog.FileName));

foreach (string file in filePaths)
{   
    if (comboBox1.SelectedItem.ToString() == "")
    {
        if (file.Contains("c"))
        {
            comboBox2.Items.Add(Path.GetFileName(file));
        }
    }
}
