issue adding images to buttons using visual studios 2022 C# for revit-CodePudding

I'm running into an issue where everything works fine until I try to throw in the images. I'm trying to pull them in as resources from inside vs. Not sure what to do here being new to C#. Below is the code that's throwing me the errors. as well as the error message.

Importing an image from Resources using the standard bitmap library in c#

Bitmap b1Image = (System.Drawing.Bitmap)(WindowsFormsApp1.Properties.Resources.ResourceManager.GetObject("Name of the image"));

You will need to replace "WindowsFormsApp1" with the correct namespace.

As you are using System.Windows.Media.Imaging you will need:

BitmapImage b1Image = (System.Windows.Media.Imaging.BitmapImage)(WindowsFormsApp1.Properties.Resources.ResourceManager.GetObject("Name of the image"));
