VB.net help -- multiple file types in .GetFiles

[Homerboy]

Right now I have the following code:

Dim di As New DirectoryInfo(SourceFolderPath.Text)
Dim Filter = "*.pdf"
Dim fiArr As FileInfo() = di.GetFiles(Filter)

but I'd like to apply more "filters" so I can pull up more than just .pdf files.
Suggestions?

Thanks in advance.

The solutions for what you want is not easy

That is what my googling has told me thus far as well.. 🙁

My initial theory was to
Filter = "*.pdf | *.doc | *.txt"

Try it

no that doesn't work in VB.net
That'd be too easy 🙂

I worked around it for now.
But I will figure it out at a later date.

Wrap another class around what you have
Pass in the filter
Parse the filter; make the GetFiles call; append the output into an array
Get the next filter and repeat.

At the end; you will have accomplished what you need and you have an array of file names containing the outputs.

I couldn't write VB to save my life, but you can get all of the files, then use Where to select the ones you want based on extensions. They aren't being filtered when you first index them, you're just keeping whichever ones match your list of extensions.

I don't write VB, but it looks alright to me.

Using the filter reduces his overhead
