Connect Xamarin to server SignalR and get data SqlDependecy RRS feed

  • Question

  • Hello everybody ! I have SQLdependency and I connect him client by Javascript

    		public static IEnumerable<Products> GetData()
    			using (var connection = new SqlConnection(ConfigurationManager.ConnectionStrings["DataBase"].ConnectionString))
    				using (SqlCommand command = new SqlCommand(@"SELECT [Guests] FROM  [1]", connection))
    					// Make sure the command object does not already have
    					// a notification object associated with it.
    					command.Notification = null;
    					SqlDependency dependency = new SqlDependency(command);
    					dependency.OnChange += new OnChangeEventHandler(dependency_OnChange);
    					if (connection.State == ConnectionState.Closed)
    					using (var reader = command.ExecuteReader())
    						return reader.Cast<IDataRecord>()
    							.Select(x => new Products()
    								Guests = x.GetString(0),
    		  function getData() {
    			  var $tbl = $('#tbl');
    				  url: 'index.aspx/GetData',
    				  contentType: "application/json; charset=utf-8",
    				  dataType: "json",
    				  type: "POST",
    				  success: function (data) {
    					  if (data.d.length > 0) {
    						  var newdata = data.d;
    						  $tbl.append(' <tr><th>ID</th><th>Name</th><th>Last Executed Date</th><th>Status</th></tr>');
    						  var rows = [];
    						  for (var i = 0; i < newdata.length; i++) {
    							  rows.push(' <tr><td>' + newdata[i].Guests + '</td></tr>');

    How can I connect to the index.aspx/GetData by Xamarin ?

  • [WebMethod]
    [ScriptMethod(UseHttpGet = true)]
    public static IEnumerable<Products> GetData()

    It's a GET not a POST.

    ASP.NET issues like SignalR and ASPX  can be addressed at the ASP.NET forums.
