Introduction

In this article, I'm going to explain how to create a Web Service in Notepad. This will perhaps help you when you are asked in an interview to create a sample Web Service in C# using Notepad.

Using the code

Just follow the steps below. It's an easy and simple exercise.

Step 1

Open Notepad and start typing. In the first line, include the Directory tag as follows:

<%@ WebService Language="C#" Class="MyClass" %>

Step 2

Type the code below in Notepad below the above line:

using System;
using System.Web.Services;
public class MyClass : System.Web.Services.WebService
{
  public MyClass()
  {
  }
  public string HelloWorld()
  {
    return "Hello Welcome to the World";
  }
}

Step 3

Check whether your class name and the name in the directory section are the same.

Step 4

Save the Notepad file as "MyWebService.asmx". Don't forget to save the file with the extension ".asmx".

How to access the Web Service

1. Copy the Web Service into the WWWRoot folder.
2. Open a new project. Select Solution Explorer.
3. Add a WebReference. In that, select Available in local machine.
4. That will list out the available Web Services. Pick the one you created just now.

That's it.
