Asp.NET 内核，发布时找不到cshtml的视图

Question

I'm using RazorEngine in my Asp.NET CORE service which generate dynamic html pages to be sent via EMAIL from a cshtml file that is stored in View folder..

The issue is that when the website is published the service is unable to find path to Views/Emails/EmailRiepilogo.cshtml as on publish the View folder is not even created...

So how can I reference to EmailRiepilogo.cshtml path when the service is published?

Here is how I'm reading the file:

string template = File.ReadAllText("Views/Emails/EmailRiepilogo.cshtml");

And here is the error:

Could not find a part of the path 'E:\VS2019\Project\bin\Debug\netcoreapp3.1\publish\Views\Emails\EmailRiepilogo.cshtml'.

Should I just create static file as cshtml?

Answer 1

You don't know where (in terms of folder structure in the host server) your application will be hosted. At the same time, methods like File.ReadAllText work best with absolute paths. You need to convert the relative path "Views/Emails/EmailRiepilogo.cshtml" to an absolute path. One way is to use IHostingEnvironment in Asp.Net Core (or Server.MapPath in Asp.Net). Just inject it to your service/controller and

string filename = Path.Combine(_hostingEnv.ContentRootPath, "Views/Emails/EmailRiepilogo.cshtml");
string template = File.ReadAllText(filename);

Of course, you need to check if the file exists where you expect after publishing the project.

我已经解决了通过将每个 cshtml 文件编译操作设置为Integrated Resource并将复制到输出目录Copy always到这样的方式来生成带有 cshtml 文件的视图文件夹并正确读取文件。

I had excact same problem. Cshtml file Build action was somehow changed from Content -> None. It worked on local but not when published to server.
