static member IsPathRooted : 
        path:string -> bool

ArgumentException

path contains one or more of the invalid characters defined in GetInvalidPathChars.

The IsPathRooted method returns true if the first character is a directory separator character such as "\", or if the path starts with a drive letter and colon (:). For example, it returns true for path strings such as "\\MyDir\\MyFile.txt", "C:\\MyDir", or "C:MyDir". It returns false for path strings such as "MyDir".

This method does not verify that the path or file name exists.
