Calling an API with Csharp

I´m new with okta.

I need to know how make an API call with c sharp in webforms.
I can’t find any code that can help me.

Thanks

Try the integration references here for .NET: https://developer.okta.com/docs/guides/sign-into-web-app/aspnet/before-you-begin/

The link does not have a c sharp samples. Only has a reference to begin in asp.net. Where i can get some code? Thanks.
