First we have a simple web service
here is the interface
using System;
using System.Collections.Generic;
using System.Linq;
using System.Runtime.Serialization;
using System.ServiceModel;
using System.Text;
// NOTE: You can use the "Rename" command on the "Refactor" menu to change the interface name "ItimeService" in both code and config file together.
[ServiceContract]
public interface ItimeService
{
[OperationContract]
string GetCurrentTime();
}
Here is the extremely simple service that implements that interface
using System;
using System.Collections.Generic;
using System.Linq;
using System.Runtime.Serialization;
using System.ServiceModel;
using System.Text;
// NOTE: You can use the "Rename" command on the "Refactor" menu to change the class name "timeService" in code, svc and config file together.
public class timeService : ItimeService
{
public string GetCurrentTime()
{
return DateTime.Now.ToLongTimeString();
}
}
You want to run this and keep it running. Start a second instance of Visual Studio to create the client. Create the reference to the service.
here is the web form for Default.aspx
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %>
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title></title>
</head>
<body>
<form id="form1" runat="server">
<div>
<h1>Time of Day</h1>
<asp:Image ID="Image1" runat="server" ImageUrl="~/the-persistence-of-memory-4.jpg"/>
<asp:ScriptManager ID="ScriptManager1" runat="server"></asp:ScriptManager>
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<ContentTemplate>
<asp:Timer ID="Timer1" runat="server" Enabled="true" OnTick="Timer1_Tick" Interval="1000" ></asp:Timer>
<asp:Label ID="lblTime" runat="server" Text="Label"></asp:Label>
</ContentTemplate>
</asp:UpdatePanel>
</div>
</form>
</body>
</html>
Here is the default.aspx.cs code
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
public partial class _Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
}
protected void Timer1_Tick(object sender, EventArgs e)
{
TimeServiceReference.ItimeServiceClient tsr = new TimeServiceReference.ItimeServiceClient();
lblTime.Text = tsr.GetCurrentTime();
}
}
