Reading a files general property of "Type of file"

GregSivers · #1 (**permalink**) March 24th, 2009, 12:36 AM

If you right click on a file (let's say a text file) and you click on properties, then general, there is a "type of file" property (this would be "Text Document" for a text file). Is there a way to access this so it can be displayed in a column of a listview?

Thanks & Regards,
Greg

You could use the

Code:

io.Path.GetExtension(filename)

I suppose if you iterate through a list of files called by the

Code:

Dim listoffiles() as string = io.directory.getFIles(dirpath)

Then you would pass the extension through a function to return its full name

Code:

Public Function GetFullName(extension as string) as stringSelect Case extensioncase ".txt"
      Return "Text Document"
case else
      Return "Unknown"
End Select
End Function

But i would look thoroughly through the io.fileinfo class aswell

Code:

Dim my_file_info as fileinfo = new io.fileinfo(filename)

I hope something in this helps.

Instead of a select case of only one option, I would suggest using an if else, less overhead and better programming. Unless you are planning to add cases.

What do you mean by overhead? I always thought that the select case was better programming then if ... else statements, i personnally find it easier to read a select statement

Well, If a better choice, if you have more than one statement. But obviously you can do it the way you want. It just that IMO a select that only has one statement and the rest fall under case else, since like is lacking something...
