How to use DFS (for dotnet) automatically to get Uploaded files's type?

Migrateduser

Hi

I use "DataObject.Contents.Add (new FileContent (Path.GetFullPath (FilePath), "jpeg")); " to upload files, but it must specify the type of file (for example: jpeg). How to use DFS (for dotnet) automatically to get Uploaded files's type?

DFC:

IDfClientX clientX = new DfClientX() ;
     IDfFormatRecognizer formatRecognizer = clientX.getFormatRecognizer(session, fileName, null) ;
     return formatRecognizer.getDefaultSuggestedFileFormat() ;

thanks!
