Code: Select all

Unhandled exception. System.NullReferenceException: Object reference not set to an instance of an object.

Hi again,

Thanks for your quick response.
I simplified the project as much as I could in order to avoid any distractions like fonts and other things, however, it still runs without any problem on windows 10 but not on Ubuntu.
The Word file is totally empty and I tried to attach just one picture to it. I use "dotnet run" in CLI when I'm in DocTest directory for running the project. The Exceptions are just like the previous post
I really need it to work!

I'm encountering similar problem with .NET 6 (Docker with mcr.microsoft.com/dotnet/aspnet:6.0 as base image) and SpireDoc 8.12.14 . Do you have any update on this (SPIREDOC-5410)?

Hi,

Thanks for your inquiry.
SPIREDOC-5410 issue in M.Mahdi.Sonic's document has not been solved yet.
For your case, did you install spire dlls for .net standard? If not, please install them via NuGet link https://www.nuget.org/packages/Spire.Officefor.NETStandard/7.9.2 and try again.
If it doesn't work, please offer the following information.
1. Your word file.
2. Your full code.
3. Your OS information, for example, ubuntu 20.04 amd64.

Amy

After adding mentioned library, I get new exception, which is good: Unable to load shared library 'libSkiaSharp'

Quick Google advised to install in Docker image libfontconfig1 and add SkiaSharp.NativeAssets.Linux nuget. Right now, it processes the file - not sure yet how it looks after opening (just tested a piece of system). A side effect is Spire.License.LicenseProvider.SetLicenseKey invocation - it started saying that it exists in 2 libraries (Spire.License and Spire.PDF)

I removed previous version of Spire.Doc (8.12.14) and license is not raising an error right now, I'm getting a PDF file with warning

Evaluation Warning: The document was created with Spire.Doc for .NET


I applied the license key which is working with mentioned verion, however it does not work with Spire.Officefor.NETStandard. Is there any other possible solution for this problem which would accept current license key?

Thank you for your feedback.
I'm sorry that I didn't find your purchase information according to your email, could you please provide your order information or authorization email? You could attach the required information here or send to us via email (support@e-iceblue.com). According to the version of Spire.Doc you provided, this version (8.12.14) is relatively old. The minimum version of Spire.Officefor.NETStandard is 6.12.1. Please try this version first. Looking forward to your test feedback.
