2Might you please edit your question to include your code in the question itself? From How to Ask: If it is possible to create a live example of the problem that you can link to (for example, on sqlfiddle.com or jsbin.com) then do so - but also copy the code into the question itself. Not everyone can access external sites, and the links may break over time.dbc– dbc2021-02-16 19:03:30 +00:00Commented Feb 16, 2021 at 19:03

What is the best way pass file from angular 11 form to asp.net core 5 web api
To achieving the requirement of posting file from angular frontend to asp.net core web api backend, you can try to create and populate a FormData object with selected file(s), then then inject the HttpClient service and use it to make request(s).
In your asp.net core web api backend, you may need to apply [FromForm] attribute to your action parameter, which would help specify that a parameter or property should be bound using posted form fields.
And you may need to configure and enable CORS in your backend to set the allowed origins and HTTP methods etc. For more information, please check the following doc:
https://learn.microsoft.com/en-us/aspnet/core/security/cors?view=aspnetcore-5.0
Besides, you can refer to the following SO threads to achieve the requirement.
