C#.Net How To: Consume a Web Service in C#.Net Visual Studio 2010

This c# tutorial explains how to consume a web service in a C# console application program. I am assuming you have already created a c# web service. Please refer my previous post on how to create a web service application and how to create simple wcf service? creating a .net web service is not a big task.


Lets follow the steps to create c# web service consumer application -

1)   Create a new C# windows console application project.

web service - create new console application

Here, I am giving name of the project as “MyFirstWebServiceConsumerApp”. Click on Ok button.

2)   Go to Solution Explorer and right click on your Console Application Project Name. In this case, right click on “MyFirstWebServiceConsumerApp” and   select “Add Service Reference…” from the drop down menu.

3)   Click on “Advance” button.

WCF Service - Add wcf service reference.

4)   Click on “Add Web Reference..” button.

WCF Service - Reference settings.

5)   An Add Web Reference window will appear. Enter here URL of the web service.

WCF Service - Add web reference popup.

Check Web Service Reference Button

6) Enter the Web Service URL and click on -> button to check whether the Web Service URL is valid or not. If the URL is valid, it will show you the available Web Methods and the status will appear as “1 Service Found:”

Enter web service reference name. I used “MyFirstWebServiceReference” as a web service reference name.

Web Service - List of all available web methods.

Now, click on “Add Reference” button.

7)   Now check the Solution Explorer. “MyFirstWebServiceReference” should be added under web reference folder.

Web Service - Solution explorer.

8)   The next step is to add Reference to our c# code. Add following line

       using MyFirstWebServiceConsumerApp.MyFirstWebServiceReference;

9)   Add code to call the web method. The final code will appear as

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

using MyFirstWebServiceConsumerApp.MyFirstWebServiceReference;

namespace MyFirstWebServiceConsumerApp

{

    class Program

    {

        static void Main(string[] args)

        {

            Service1 webService = new Service1();

            Console.WriteLine(webService.MyFirstWebMethod("Bradd", "Pitt"));

            Console.ReadLine();

        }

    }

}

 

10) Now hit F5 button on keyboard to execute the code. The result should appear as

Web Service - Consumer output.

Your fi­rst web service consumer console application is ready.
