Wcf using NetTcpBinding

3)Open method launches the Service.
 
 
4) EndPointAddress class
 
Provides a unique network address that a client uses to communicate with a service endpoint. It is specified both in the server and the client and must be the same.   
 
5) ChannelFactory class
It is a generic class that creates and manages the channels that are used by clients .to send messages to service endpoints. 

For this, I have taken 3 applications
 

 
The A,B,C’s of  WCF have been configured manually using the appropriate classes.
 
System.ServiceModel.dll has been included and the appropriate  namespaces and classes have been included  
to provide the implementation.
 
1)Business Component
 
The code for the Business Component has been defined in 2  files .First one is the interface  file and second one is the
 
Class file that implements the interface logic. The name of the class library project was remlbb.
 
Add reference to System.ServiceModel.dll
 
Code of the interface 

using System; 
using System.Collections.Generic; 
using System.Linq; 
using System.Text; 
using System.ServiceModel; 
namespace remlbb 
{ 
    [ServiceContract] 
    public interface myinterface 
    { 
        [OperationContract] 
  
        string Upload(string s); 
  
    } 
}

 
 
Delete the default class definition. Code of the class providing the implementation
 

using System; 
using System.Collections.Generic; 
using System.Linq; 
using System.Text; 
  
namespace remlbb 
{ 
    public class implementclass : myinterface 
    { 
        public string Upload(string s) 
        { 
            return "hello" + "--" + s; 
  
        } 
    } 
} 

 
Build the project. It would create remlbb.dll   
 

• The Server Application for providing the Hosting environment Give your own name to the application. I named it as WindowsFormsApplication7mar. 
• Take 2 buttons and change their Text to Start and Stop 
• Add reference to System.ServiceModel.dll and remlbb.dll   

Type this code in the  Form1.cs file

using System; 
using System.Collections.Generic; 
using System.ComponentModel; 
using System.Data; 
using System.Drawing; 
using System.Linq; 
using System.Text; 
using System.Windows.Forms; 
using System.ServiceModel; 
using remlbb; 
  
namespace WindowsFormsApplication7mar 
{ 
    public partial class Form1 : Form 
    { 
        ServiceHost host; 
        public Form1() 
        { 
            InitializeComponent(); 
        } 
  
        private void button1_Click(object sender, EventArgs e) 
        { 
            host = new ServiceHost(typeof(implementclass)); 
            NetTcpBinding binding = new NetTcpBinding(); 
            host.AddServiceEndpoint(typeof(myinterface), binding, new Uri("net.tcp://localhost:5000/implementclass"));
            
  
            host.Open(); 
            MessageBox.Show("started"); 
            button1.Enabled = false; 
            button2.Enabled = true; 
            
        } 
  
        private void button2_Click(object sender, EventArgs e) 
        { 
            host.Close(); 
  
            button1.Enabled = true; 
            button2.Enabled = false; 
  
  
        } 
    } 
}

 
 
Client Application
 

• Give your own name to  a Windows application. I named it as WindowsFormsApplication1. 
• Take 1 button and  1 TextBox.  
• Add reference to System.ServiceModel.dll and remlbb.dll 

 
 The code of the  Client  is like this (Form1.cs)
 

using System; 
using System.Collections.Generic; 
using System.ComponentModel; 
using System.Data; 
using System.Drawing; 
using System.Linq; 
using System.Text; 
using System.Windows.Forms; 
using System.ServiceModel; 
using remlbb; 
  
namespace WindowsFormsApplication1 
{ 
    public partial class Form1 : Form 
    { 
        myinterface idd; 
        public Form1() 
        { 
            InitializeComponent(); 
        } 
  
        private void Form1_Load(object sender, EventArgs e) 
        { 
            NetTcpBinding binding = new NetTcpBinding(); 
  
            EndpointAddress addr = new EndpointAddress("net.tcp://localhost:5000/implementclass"); 
  
            ChannelFactory<myinterface> chn = new ChannelFactory<myinterface>(binding, addr); 
  
            idd = chn.CreateChannel(); 
        } 
  
        private void button1_Click(object sender, EventArgs e) 
        { 
            string y = idd.Upload(textBox1.Text); 
  
            MessageBox.Show(y); 
        } 
    } 
} 

 
To Execute:-
 
 

1. Click the exe of the server application  
2. Click the start button  
3. Click the exe of the client application   
4. Enter some text in the text box and press the Button. It should  display the  text entered in a textbox concatenated with  Hello. 
5. To stop the service, click the stop button in the exe of server application 

Happy Coding !
