From my C# console application, I want to issue an Uri update request. Like the following:

http://username:password@dynupdate.no-ip.com/nic/update?hostname=mytest.testdomain.com&myip=1.2.3.4

I have tried the following:

string url = "http://username:password@dynupdate.no-ip.com/nic/update? hostname=mytest.testdomain.com&myip=1.2.3.4";
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
request.Timeout = 5000;

But, I am getting, Invalid URI: The format of the URI could not be determined. error.

Any idea, where I went wrong? I type the full url as shown above into a web browser and it works as expected but through the C# application, it throws an exception.

Is there any other way to implement this?

    You need to create and add some credentials to the request and then access the URI without passing in the username/password.

    For more information : How to: Request Data Using the WebRequest Class (Specifically the section regarding credentials)

    For example;

    var uri = new Uri("http://somesite.com/something");
var request = WebRequest.Create(uri) as HttpWebRequest;
request.Credentials = new NetworkCredential("myUserName","myPassword");
request.PreAuthenticate = true;
