ASP.NET Core - Not able to read static HTML file using C# StreamReader inside Controller

Question

I have a asp.net core project with angular template with below files structure.

I want to read the static HTML file (EmailConfirmation.html) from Template folder.

My code to read this file inside a controller as below.

string body = string.Empty;
using (StreamReader reader = new StreamReader("./Template/EmailConfirmation.html"))
{
body = reader.ReadToEnd();
}

But when I publish this app to azure, There is no folder created with the name Template inside wwwroot folder. Thus caught with an error

Something went wrong: System.IO.DirectoryNotFoundException: Could not find a part of the path 'D:\home\site\wwwroot\Template\EmailConfirmation.html'

For your note : I have tried with steps mentioned in the below article

https://learn.microsoft.com/en-us/aspnet/core/fundamentals/static-files?view=aspnetcore-2.2

But not worked out !

How can I solve this problem. Thanks for your attention. I’m looking forward to your reply.

You need to include the file in your project file for the build to copy it to your output folder. Something like this: stackoverflow.com/questions/54762744/… — Setherith

Drop your Template folder into the wwwroot folder instead and it should work fine from there or configure as per tutorial. — Vidmantas Blazevicius

Stratup.cs

public void Configure(IApplicationBuilder app)
{
     app.UseStaticFiles(new StaticFileOptions()
     {
        FileProvider = new 
        PhysicalFileProvider(Path.Combine(Directory.GetCurrentDirectory(), @"Templete")),
                RequestPath = new PathString("/Templete")
     });
}

Controller Action

string body = string.Empty;
//using streamreader for reading my htmltemplate   
using (StreamReader reader = new StreamReader(Path.Combine("Templetes", "EmailConfirmation.html")))
{
   body = reader.ReadToEnd();
}

Try this:

using (var reader = File.OpenText(Path.Combine(@"./templates", $"{templateFileName}.html")))
        {
            return reader.ReadToEnd();
        }
