Parameters
- fileName
- String
[in] The file name from which to get the extension to look for.

If successful, returns a zero-based index into the file extension list that is returned from GetFormatFilterList(); otherwise, returns -1 to indicate the extension is not in the file extension list.
Remarks
This is used to select the appropriate filter when showing a Save As dialog box to save a file.
The base method calls Microsoft.VisualStudio.Package.LanguageService.GetFormatFilterList and then searches the list for the extension. Note that Microsoft.VisualStudio.Package.LanguageService.GetFormatFilterList returns a single string: the extensions are separated either by newlines or vertical bars ("|") and the base method can handle either separator.
