Get Value from Header ASP.Net Core

Question

Hi All,

 

I want to get value from the header.

Means when I pass the parameter from header, I need the value using key from the headers.

 

WebClient webClient = new WebClient();
webClient.QueryString.Add("param1", "value1");
webClient.QueryString.Add("param2", "value2");
string result = webClient.DownloadString("http://theurl.com");

 Is there any one have idea?
