This is not a good question - we cannot work out from that little what you are trying to do.
Remember that we can't see your screen, access your HDD, or read your mind - we only get exactly what you type to work with.
Use the "Improve question" widget to edit your question and provide better information.

I follow this example: https://docs.microsoft.com/en-us/dotnet/api/documentformat.openxml.packaging.spreadsheetdocument?view=openxml-2.8.1#examples

It is a console application with a call to Console.ReadKey(); at the end. So it is waiting for you to press a key to terminate the program.

I put it into a asp.net core project. So I wait a long time.

You cannot use Console methods in an ASP.NET project.

Why, I add this as a method to be called by the controller.

I don't know what happened, it cost long time, and the console prompts stack overflow last.
