MimeTypeGetFileTypeExtension Method

public string GetFileTypeExtension(
	bool includePeriod = true
)

Public Function GetFileTypeExtension ( 
	Optional includePeriod As Boolean = true
) As String

public:
String^ GetFileTypeExtension(
	bool includePeriod = true
)

member GetFileTypeExtension : 
        ?includePeriod : bool 
(* Defaults:
        let _includePeriod = defaultArg includePeriod true
*)
-> string 

Parameters

includePeriod  Boolean  (Optional)

true specifies, that the period "." (U+002E) is included in the retrieved file type extension, false, that it's not.

Return Value

If no other file type extension can be found, DefaultFileTypeExtension is returned. includePeriod specifies whether the period is included.

Internally a small memory cache is used to retrieve often used file type extensions faster. You can enlarge the size of this cache with MimeCache.EnlargeCapacity(int) or you can delete it with MimeCache.Clear() if your application does not need it anymore.
