File->New->Web Site->(Visual C#) ASP.Net Web Service

Press F5 and Run the application and Copy the URL

Client:

File->New->Project->(Visual C#) Console Application

Go to Solution Explorer-> Right Click on Reference->Choose Add Service Reference

Paste the URL in Address Bar & Click Go Button

Sample code:[Server]

using System;

using System.Collections.Generic;

using System.Linq;

using System.Web;

using System.Web.Services;

[WebService(Namespace = "http://tempuri.org/")]

[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]

// To allow this Web Service to be called from script, using ASP.NET AJAX, uncomment the following line.

// [System.Web.Script.Services.ScriptService]

public class Service : System.Web.Services.WebService

{

public Service () {

//Uncomment the following line if using designed components

//InitializeComponent();

}

[WebMethod]

public string HelloWorld()

{

return "Everybody listen....";

}

[Client]

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

namespace trial

{

class Program

{

static void Main(string[] args)

{

ServiceReference.ServiceSoapClient gs = new ServiceReference.ServiceSoapClient();

System.Console.WriteLine("Response message:"+gs.HelloWorld());

System.Console.ReadLine();

}

Simple output display

public static void main(String args[])
{
int i=1;
int j;
while(i<=7){
for(j=1;j<=i;j++)
System.out.print("*");
i=i+2;
System.out.println("");
}
i=5;
while(i>=1){
for(j=1;j<=i;j++)
System.out.print("*");
i=i-2;
System.out.println();
}
}
