Reference Local File in C# .NET Core 6.0-CodePudding

We use EPPlus to build and export Excel files. In this scenario, we have a complex template that would be easier to fill in than build from scratch. Assuming we have two folders at the root of the .NET Core 6.0 project, "/Controllers" and "/Templates", I'd like to be able to reference the template from a controller in the "Controllers" folder using a relative path such as "../Templates/template.xlsx".

CodePudding user response：

you can get the path with IWebHostEnvironment. Inject it into your controller.. and..

string path = Path.Combine(_webHostEnvironment.ContentRootPath, "Templates");

string filename = "template.xlsx";

string fullfile = Path.Combine(path, filename);

be sure to check if the directory exists

CodePudding user response：

You can do something like this from your controller. and it will reference the file wherever you deploy code. Not a relative path but still usable in controller code.

string path = Path.Combine(Environment.CurrentDirectory, @"Templates\template.xlsx");

Of course make sure directory and file exist, but if its in code they it should.
