  1. POUsing WebClient to download string from ASP.NET Web Service Error
    text
    copied!<p>I have a simple ASP.NET Web Service:</p> <pre><code>using System; using System.Collections.Generic; using System.Web; using System.Web.Services; using System.Web.Script.Services; using System.Web.Script.Serialization; using System.Web.UI.WebControls; using System.Web.UI; namespace WebService1 { /// &lt;summary&gt; /// Summary description for Service1 /// &lt;/summary&gt; [WebService(Namespace = "http://tempuri.org/")] [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)] [System.ComponentModel.ToolboxItem(false)] [ScriptService] public class Service1 : System.Web.Services.WebService { [WebMethod] [ScriptMethod(ResponseFormat = ResponseFormat.Json)] public string Get() { member mem = new member(); mem.hello = "hello hello hello"; mem.kalon = "fafasdf"; mem.name = "wfasdfawe"; return new JavaScriptSerializer().Serialize(mem); } [WebMethod] public string HelloWorld() { return "Hello World"; } } public class member { public string hello { get; set; } public string name { get; set; } public string kalon { get; set; } } } </code></pre> <p>I'm facing problem to retrieve the string from SilverLight by using WebClient. Can you enlighten me? I uses the below code to get the string from the WebService.</p> <pre><code>WebClient wc = new WebClient(); public MainPage() { InitializeComponent(); wc.DownloadStringCompleted += new DownloadStringCompletedEventHandler(wc_DownloadStringCompleted); } private void button1_Click(object sender, RoutedEventArgs e) { Uri uri = new Uri("http://www.MyWeb.com/Service1.axms/Get"); wc.DownloadStringAsync(uri); } void wc_DownloadStringCompleted(object sender, DownloadStringCompletedEventArgs e) { MessageBox.Show(e.Error.ToString()); MessageBox.Show(e.Result); } </code></pre> <p>And I receive error:</p> <p>System.Security.SecurityException ---> System.Security.SecurityException: Security error. at System.Net.Browser.BrowserHttpWebRequest.InternalEndGetResponse(IAsyncResult asyncResult) at System.Net.Browser.BrowserHttpWebRequest.&lt;>c_<em>DisplayClass5.b</em>_4(Object sendState) at System.Net.Browser.AsyncHelper.&lt;>c_<em>DisplayClass4.b</em>_1(Object sendState) --- End of inner exception stack trace --- at System.Net.Browser.AsyncHelper.BeginOnUI(SendOrPostCallback beginMethod, Object state) at System.Net.Browser.BrowserHttpWebRequest.EndGetResponse(IAsyncResult asyncResult) at System.Net.WebClient.GetWebResponse(WebRequest request, IAsyncResult result) at System.Net.WebClient.DownloadBitsResponseCallback(IAsyncResult result)</p> <p>I have tried this too, still getting the same error:</p> <pre><code>Uri uri = new Uri("http://www.MyWeb.com/Service1.axms?op=Get"); wc.DownloadStringAsync(uri); </code></pre> <p>1 more question: Is the url like this correct to get the string?</p> <pre><code>http://www.MyWeb.com/Service1.axms?op=Get http://www.MyWeb.com/Service1.axms/Get </code></pre>
