DinkToPdf Net Core 无法加载 DLL 文件 [英] DinkToPdf Net Core not able to load DLL files

问题描述

我正在尝试使用 DinkToPdf 库从 HTML SQL 服务器数据库生成 PDF.

I am trying to generate PDFs from HTML SQL server database using DinkToPdf library.

在我添加的启动文件中:

In the startup file I have added:

var context = new CustomAssemblyLoadContext();
context.LoadUnmanagedLibrary(Path.Combine(Directory.GetCurrentDirectory(), "libwkhtmltox.dll"));

该行在启动网络应用程序时给了我这个错误:

The line gives me this error on launching the web app:

DllNotFoundException:无法加载 DLL 'C:Program FilesIIS Expresslibwkhtmltox.dll' 或其依赖项之一:找不到指定的模块.(来自 HRESULT 的异常:0x8007007E)

DllNotFoundException: Unable to load DLL 'C:Program FilesIIS Expresslibwkhtmltox.dll' or one of its dependencies: The specified module could not be found. (Exception from HRESULT: 0x8007007E)

System.Runtime.Loader.AssemblyLoadContext.InternalLoadUnmanagedDllFromPath(string unmanagedDllPath)

System.Runtime.Loader.AssemblyLoadContext.InternalLoadUnmanagedDllFromPath(string unmanagedDllPath)

DllNotFoundException:无法加载 DLL 'C:Program FilesIIS Expresslibwkhtmltox.dll' 或其依赖项之一:找不到指定的模块.(来自 HRESULT 的异常:0x8007007E)

推荐答案

我找到了一些变通方法.它们并不完美但值得一试，它们确实提供了帮助，我能够从 SQL Server 生成 PDF.我将 .dll 文件放在以下文件夹中，它工作正常.

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 FilesIIS Express

C:Program FilesIIS Express

和加载的 .dll 文件

and the loaded the .dll files with

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

我走整条路的另一种方式

The other way I went for the whole Path

context.LoadUnmanagedLibrary(Path.GetFullPath(@"C:UsersUsersource
eposWebSolutionWebApplibwkhtmltox.dll"));

他们都工作了.但是，我敦促 Net Core 开发人员在 GetCurrentDir 上工作得很好.或从项目或解决方案文件夹加载的方法

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");
