推荐答案

我找到了一些解决方法.它们并不完美，但是值得一试，它们确实提供了帮助，并且我能够从SQl Server生成PDF.我将.dll文件放在以下文件夹中，并且可以正常工作.

I found some work-arounds. They are not perfect but worth a try, and they did do help and I was able to generate PDFs from SQl Server. I put the .dll files in the following folder and it worked.

C:\ Program Files \ IIS Express

C:\Program Files\IIS Express

并使用

Path.Combine(Directory.GetCurrentDirectory(), "libwkhtmltox.dll");

我走遍整个路径的另一种方式

The other way I went for the whole Path

context.LoadUnmanagedLibrary(Path.GetFullPath(@"C:\Users\User\source\repos\WebSolution\WebApp\libwkhtmltox.dll"));

他们两个都工作了.但是，我敦促Net Core开发人员在GetCurrentDir上做得很好.或从项目或解决方案文件夹中加载的方法

Both of them worked. However, I urge Net Core developers to work on the GetCurrentDir very well. Or a Method to load from the Project or Solution Folder

Path.Combine(Directory.GetCurrentDirectory(), "libwkhtmltox.dll");
