How to get file type within SPFile

Question

Hi,
I have a document library and I would like to get the type of document so it can be displayed for the user
Currently I have this code
foreach (SPListItemVersion version in item.Versions)
if (version.Level == SPFileLevel.Published)
string fileicon = version.ListItem.File.IconUrl;
string filetype = version.ListItem.File.Item.ContentType.Name;
string filesize = (version.ListItem.File.Length / 1024).ToString();
string filetitle = version.ListItem.File.Item.Title;
string filepath = version.ListItem.File.ServerRelativeUrl;
Within the code I get the "ListItem.File.Item.ContentType.Name" and this always returns "Document" even if its a Word Document, Spreadsheet, jpg or PDF.
I really want to display, Document, spreadsheet, pdf, etc etc
How do I get this property??
Thanks
Marc

You can use the ListItem.File.Name property to get the full file name including the extension, you could then parse this to get just the extension and determine the file type based on that.
Note that when parsing the file name, if you try to do it by splitting the filename using the period symbol "." as the seperator you will need to allow for file names which contain multiple period symbols. You may be able to use the System.IO.FileInfo class to help, it has an instance property 'Extension' which should take care of that for you, though getting an SPFile into a FileInfo object may be more hassle than just writing your own quick parser, I haven't tried it.
