Creating and consuming web service in ASP.NET MVC

• First of all we'll create a Web Service and then we'll consume the web service using ASP.NET MVC application.
• This project is created on Visual Studio 2013.
• Open a VS and select ASP.NET Empty web application as shown.

• Then add new item and select Web Service (.asmx) extension would be there, rename if you want. Finally it would be some thing like this.

• Above you can see a [web method] , actually this allows a  methods to call remotely and access the data.
• When you'll run the program you'll see HelloWorld method which is created by default. Now there after you'll invoke the HelloWorld which will return output as "Hello World".

• In a same way we'll create a Simple Web Method for addition of two numbers named Calc which will return a string. One can go through below code , we've created new method Calc which takes 3 inputs:

1. query:  For Add, Multiply, etc 
2. num1: number
3. num2: number

• Here it's only shown for Addition you can do as you want.

• Now after creating the web method you'll see Calc method would be created. For testing your created service you can go to Calc and click. 

• 
  

• After click input Add and two numbers as shown and click on invoke. Be sure it should show result as in XML format and addition of two numbers.

• Now we'll consume a Web Service using ASP.NET MVC application. So create an Empty ASP.NET MVC Application as shown below. 

• Before consuming Web Service above created project should be running or hosted on IIS to access.
• Then add that url in this Address and Press Go. Your hosted or running Web Service would be seen in Service Panel as shown.

• For accessing the method give a reference of Web Service in namespace as shown.

•  Thereafter create an object as shown by SoapClient and then give input to Web Method by calling the service and you'll get the output.

• And that's it Over.  You'll get your data in result and can use in View of MVC application.
