Consuming web service in console application

Introduction

Here I am creating a simple web service and using it in a console application. Using a web service in a console application is similar to using a web service in window application. At first, we create a web service. Follow the given steps.

• Create new project
• Select ASP.NET Empty Web Application
• Give name to your project and click ok button
• Go to Solution Explorer and right click at your project
• Select Add New Item and select Web Service application
• Give it name and click ok button 

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Services;
 
namespace myproject
{
    /// <summary>
    /// Summary description for MyService
    /// </summary>
    [WebService(Namespace = "example.abc/")]
    [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
    [System.ComponentModel.ToolboxItem(false)]
    // 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 MyService : System.Web.Services.WebService
    { 
        [WebMethod(Description="show simple message")]
        public string show()
        {
            return "My Web Service Application";
        }
        [WebMethod(Description = "show datetime")]
        public string showdate()
        {
            return DateTime.Now.ToLongDateString();
        }
        [WebMethod(Description = "addition of two int")]
        public int add(int a,int b)
        {
            return a + b;
        }  
    }
}

Run the application

Output window:

 

Now, create a new project and take Console Application.  Add the service reference. For doing this, follow the given steps.

• Go to Solution Explorer and right click at your application.
  
  

• Click Add Service Reference. A new window will be open.

• Click the "Advanced" button. A new window will be open.

      

• Again click the "Add Web Reference" button. Again a new window will be open.

• Copy the URL of your running service application and paste to it at URL( As given in above figure) and click the "Go" button.
  

• Set the service reference name. The default name is "localhost". Now click the "Add Reference" button.
  

namespace MyApplication
{
    class Program
    {
        static void Main(string[] args)
        {
            myservicereference.MyService obj = new myservicereference.MyService();
            Console.WriteLine(" Calling Web Methods");
            Console.WriteLine("---------------------");
            Console.WriteLine("\n Calling show Method");
            Console.WriteLine("  "+obj.show());
            Console.WriteLine("\n\n"+" Calling showdate Method ");
            Console.WriteLine("  "+obj.showdate());
            Console.WriteLine("\n Calling add Method ");
            Console.Write("  Enter First Number:");
            int a = Convert.ToInt32(Console.ReadLine());
            Console.Write("  Enter Second Number:");
            int b = Convert.ToInt32(Console.ReadLine());
            Console.WriteLine("\n  Addition is:" + obj.add(a, b).ToString());
            Console.ReadLine();
        }
    }
}
 
Press Ctrl+f5 to run the code.

Output:

 

 Enter first and second number. Then press "enter".
