Question

我正在使用Select.Pdf制作我的角度应用程序页面的PDF文件。

Select.Pdf正在.Net.Core 4.6.2的服务器端破坏。

这是进行转换的代码

SelectPdf.HtmlToPdf converter = new SelectPdf.HtmlToPdf();    
SelectPdf.PdfDocument doc = converter.ConvertUrl(url);
return doc.Save();

由于某种原因，ConvertUrl方法以下面列出的异常结束

System.Exception
  HResult=0x80131500
  Message=Conversion failure. Attempt by security transparent method 'SelectPdf.Lib.ស.ᜃ()' to access security critical method 'System.Runtime.InteropServices.Marshal.AllocHGlobal(Int32)' failed.

Assembly 'Select.Pdf, Version=18.4.0.0, Culture=neutral, PublicKeyToken=e0ae9f6e27a97018' is marked with the AllowPartiallyTrustedCallersAttribute, and uses the level 2 security transparency model.  Level 2 transparency causes all methods in AllowPartiallyTrustedCallers assemblies to become security transparent by default, which may be the cause of this exception.
  Source=Select.Pdf

有人知道此异常的根本原因是什么吗？
