What is the best way in .Net to handle authentication & authorization protocols for downloading a file via https

Question

Hi all;

We need to implement pretty much every common authentication & authorization protocol for both reading files and OData queries from a url via https. We need this for both .Net Framework & .Net Core.

Is there a way to do this generically in the .Net runtime? Or is there a listing somewhere of how to call .Net to get this.

Or any other ways to solve this problem?

thanks - dave

Hi,DavidThielen-2188

You can use WebClient.DownloadFile() to download the file from url and set authentication at the same time, like:
DownloadFileFromUrl

WebClient.DownloadFile

using (System.Net.WebClient wc = new System.Net.WebClient())  
{  
	wc.Headers.Add("Cookie: Authentication=user"); // add a cookie header to the request  
	try  
	{  
		string filename = System.Guid.NewGuid().ToString("N"); // use global unique identifier for file name to avoid conflicts  
		wc.DownloadFile("http://www.prowaretech.com/", "C:\\files\\" + filename); // could add file extension here  
		// do something with file  
	}  
	catch (System.Exception ex)  
	{  
		// check exception object for the error  
	}  
}
