In .NET Core there are multiple ways to access HttpContext like IHttpContextAccessor.

When you have the Context you can simply use this method:

httpContext.Request.QueryString.Value

Usage:

URL: https://localhost:44335/test?key=123

var key = System.Web.HttpUtility.ParseQueryString(httpContext.Request.QueryString.Value).Get("key");
