Methods

  • Changes the extension of a path string.

    Parameters

    • path: FilePath

      The path information to modify. The path cannot contain any of the characters defined in System.IO.Path.GetInvalidPathChars.

    • extension: string

      The new extension (with or without a leading period). Specify null to remove an existing extension from path.

    Returns FilePath

    The modified path information.On Windows-based desktop platforms, if path is null or an empty string (""), the path information is returned unmodified.
