System.IO.FileNotFoundException: Could not load file or assembly System.Windows.Forms
Hi
When I use below in my Web API with .NET8 .
Stimulsoft.Report.StiReport report = new Stimulsoft.Report.StiReport();
The error happened:
System.IO.FileNotFoundException: Could not load file or assembly 'System.Windows.Forms, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'. 系统找不到指定的文件。 File name: 'System.Windows.Forms, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' at Stimulsoft.Report.StiReport..ctor() at OrBitCoreService.CLRService.CLR_MRZPrint(String& ReturnMessage, String SQLString, String MRZFile, String PrinterOrFile, Int32 ImageResolution) in D:\OrBitCoreService\CLRService.cs:line 3239
but Webservice with .NET Framework works OK
Anybody knows the reason?
Thanks very much.

Hello,
You should use the Stimulsoft.Reports.Engine.NetCore package instead of the Stimulsoft.Reports.Engine.
Thank you.

Thank you.
The Stimulsoft.Reports.Engine.NetCore works OK ,but the new error happened.
Code as below:
Stimulsoft.Report.StiReport report = new Stimulsoft.Report.StiReport();
report.Load(@"d:\abc.mrt");
report.RegData(JsonDS);
report.Render();
System.Drawing.Printing.PrinterSettings printer = new System.Drawing.Printing.PrinterSettings();
printer.PrinterName = "HP Printer"
report.Print(false, printer);
System.Exception:
Printing does not work with a graphics engine based on ImageSharp. Please switch Stimulsoft.Drawing.Graphics.GraphicsEngine to Gdi. at Stimulsoft.Report.Print.StiPrintProvider.Print(StiReport report, Boolean showPrintDialog, Int32 fromPage, Int32 toPage, Int16 copies, PrinterSettings printerSettings)
Thanks for you help
Henry

Hey Lech
This code works OK, thank you.
but in the Stimulsoft.Reports.Engine.NetCore 2024.2.2
there is a new problem for display Chinese characters.

Re: System.IO.FileNotFoundException: Could not load file or assembly System.Windows.Forms
Hello,
Most of the standard fonts do not contain national characters. In this case, Windows uses the "font fallback". This algorithm is very complicated and, therefore, is not realized in the exports. To output national characters, please, use the font which contains all necessary characters. For example, the "Arial Unicode MS" font contains many national characters.
Also, you should load the font file to a special font collection using
StiFontCollection.AddFontFile(name).
Thank you.

Although when I use "Arial Unicode MS", the Chinese characters is missing yet.
In Stimulsoft reports for .NET Framework , this problem is not exists .

Hello,
Do you add the file in the font collection?
Thank you.
