Hi,Support:

Dim Html As New Aspose.Html.HTMLDocument()
'throw and exception System.Reflection.ReflectionTypeLoadException

Therefore, the api cannot be correctly used any more. How to fix it?

The exception you are encountering, System.Reflection.ReflectionTypeLoadException, typically occurs when there is an issue with loading types from an assembly. This can happen due to various reasons, such as missing dependencies or version mismatches.

Here are some steps you can take to troubleshoot and potentially resolve the issue:

  1. Check Dependencies: Ensure that all required dependencies for Aspose.Html are correctly referenced in your project. Sometimes, missing or incompatible versions of dependent assemblies can lead to this exception.

  2. Update Aspose.Html: Make sure you are using the latest version of Aspose.Html. If you are using version 23.5, consider updating to a newer version if available, as it may contain bug fixes and improvements.

  3. Target Framework: Verify that your project is targeting the correct .NET Framework version. You mentioned using .NET Framework 4.6.1; ensure that this is compatible with the version of Aspose.Html you are using.

  4. Error Handling: Since you are already using a Try/Catch block, ensure that you are logging the full exception details, including the inner exceptions, which may provide more insight into what is causing the issue.

  5. Investigate Other Add-ins: If you are using other add-ins or libraries that also utilize Aspose, there may be conflicts. Try isolating the Aspose.Html usage to see if the issue persists.

  6. Contact Support: If the problem continues, consider reaching out to Aspose support with detailed information about your environment and the exception stack trace. They may have additional insights or may already be aware of similar issues.

If you need further assistance, please provide more details about your setup, and I will do my best to help you.
