Multiple file extensions in OpenFileDialog

Question

How can I use multiple file extensions within one group using OpenFileDialog? I have Filter = "BMP|*.bmp|GIF|*.gif|JPG|*.jpg|PNG|*.png|TIFF|*.tiff" and I want to create groups so JPG are *.jpg and *.jpeg, TIFF are *.tif and *.tiff and also 'All graphic types'? How can I do that?

Try:

Filter = "BMP|*.bmp|GIF|*.gif|JPG|*.jpg;*.jpeg|PNG|*.png|TIFF|*.tif;*.tiff"

Then do another round of copy/paste of all the extensions (joined together with ; as above) for "All graphics types":

Filter = "BMP|*.bmp|GIF|*.gif|JPG|*.jpg;*.jpeg|PNG|*.png|TIFF|*.tif;*.tiff|"
       + "All Graphics Types|*.bmp;*.jpg;*.jpeg;*.png;*.tif;*.tiff"

I would suggest putting the "ALL" option first, as that what seems to be the default. – John Grabanski Nov 22 '16 at 20:44
Don't put a `|` in the description part, it will miss-parse it. – CAD bloke Jul 14 '20 at 23:04

This is from MSDN sample:

(*.bmp, *.jpg)|*.bmp;*.jpg

So for your case

openFileDialog1.Filter = "JPG (*.jpg,*.jpeg)|*.jpg;*.jpeg|TIFF (*.tif,*.tiff)|*.tif;*.tiff"

This solution is more elegant, correct and desired. This should be the most up-voted solution. – Dr. Cogent Feb 28 '17 at 14:22

Based on First answer here is the complete image selection options:

Filter = @"|All Image Files|*.BMP;*.bmp;*.JPG;*.JPEG*.jpg;*.jpeg;*.PNG;*.png;*.GIF;*.gif;*.tif;*.tiff;*.ico;*.ICO
