I am making a .NET Core 3.1 WPF App its building successfully! But when I run a custom print function which is using System.Drawing it throw this error:

Exception thrown: 'System.IO.FileNotFoundException' in System.Drawing.Common.dll

I even tried to install via NuGet:

App is building successfully but when I try to run the print function it throw error and print blank page.

Funny thing is same codes are working with a console app

Below is detail about console app

Same Version Of System.Drawing.Common also not working

##Code For Print Function >>

public static void Print()
        {
            PrintDocument p = new PrintDocument();
            p.PrintPage  = delegate (object sender1, PrintPageEventArgs e1)
            {
                graphics = e1.Graphics;

                 Bitmap logo = (Bitmap)Bitmap.FromFile(path, false);
            graphics.DrawImage(logo, new Point(25, (int)Offset));

            layout = new RectangleF(new PointF(startX   75, startY   Offset   25), layoutSize);
            graphics.DrawString("Receipt", font10, brush, layout, formatCenter);
    };
            try
            {
                p.Print();
            }
            catch (Exception ex)
            {
                Console.WriteLine("Exception Occured While Printing \n"   ex);
            }
        }

CodePudding user response：

The issue you have is that the path in WPF version will not be found, see

Bitmap.FromFile(path, false),

not the problem with System.Drawing.Common.dll

Ensure there is a file for path.
