C# Don't display filter extensions in OpenFileDialog

I have multiple extensions in the Filter property of OpenFileDialog. Is possible to hide the extensions and show only the description?

Sample:

dialog.Filter = "Image files|*.bmp;*.jpg; many image file extensions here"

I want to show only the text: "Image files" in the file type combo box because the extension string is very long. Is this possible?

It is very simple, you know. See the following code snippet. It will run perfectly. You can define more file-types like this way.

OpenFileDialog dialog = new OpenFileDialog();
dialog.Filter = "JPG Files(*.jpg)|*.jpg|PNG Files(*.png)|*.png|BMP Files(*.bmp)|*.bmp|GIF Files(*.gif)|*.gif|TIFF Files(*.tiff)|*.tiff|All Files(*.*)|*.*";

There are two parts in the Filter property. "JPG Files(.jpg)|.jpg" means the dropdown for selecting file-types will show "JPG Files(*.jpg)" and the filter will happen against the next part of pipe character i.e. *.jpg.

Note: Never use any space after *.jpg or be it any other file-type. If used, it cannot filter your desired file-type.

This

dialog.Filter = "Image files (*.bmp)|*.bmp;*.jpg"

will only display "Image files (*.bmp)" in the combo box while still showing files with all the specified extensions.

Or you could do

dialog.Filter = "Image files (*.bmp;...)|*.bmp;*.jpg"

to indicate that it looks for files with extension bmp and some other extensions.

This might depend on the OS. I tested with Windows 7.

This should work:

    dialog.Filter = "All Supported Audio | *.mp3; *.wma | MP3s | *.mp3 | WMAs | *.wma";
    dialog.AutoUpgradeEnabled = false; //using FileDialog.AutoUpgradeEnabled = false it will display the old XP sytle dialog box, which then displays correctly
    dialog.ShowDialog();

It should work exactly as you wrote in your question:

dialog.Filter = "Image files|*.bmp;*.jpeg;*.jpg;*.png;*.gif"
