Call restful service using button click

Question

I wish to call the get function from a button click on my web application

my code in my application is

protected void btngetbtanches_Click(object sender, EventArgs e)
    {
        try
        {


            HttpWebRequest req = WebRequest.Create(@"http://localhost:54691/") as HttpWebRequest;

            WebResponse resp = req.GetResponse();
            using (Stream branchstream = resp.GetResponseStream())
            {
                            StreamReader loResponseStream =
            new StreamReader(branchstream, Encoding.UTF8);

            string Response = loResponseStream.ReadToEnd();

            loResponseStream.Close();
            resp.Close();
            }
            }
        catch (Exception ex)
        {

        }
    }

in my service is

    [ServiceContract]
    public interface IRestSerivce
    {
        [OperationContract]
        [WebGet(UriTemplate = "Default")]
        string GetBranchData();


    }     
}

}

get data is defined in another file in the service project. When I try to click the button some html is returned and the service is not called.

Any help would be appreciated

It looks like the butoon is returning the front page of the service, but not going through to getdata — TraceyB, Jun 26 '17 at 15:15
I think your url is incorrect; it should at least contain `GetBranchData` — Stefan, Jun 26 '17 at 16:05

Your web request does not match the end point of the service:

You should try:

HttpWebRequest req = WebRequest.Create
        (@"http://localhost:54691/RestSerivce/GetBranchData") as HttpWebRequest;

or at least the one which matches your routing.

You can also add the service as reference and consume it's type, which is a common approache.
