Footstep ane

Open up Visual Studio and select "File" -> "New" -> "Web Site...".

Step two

At present add a Web Service file (.asmx) to the Web site.

Provide a name for the web service file.

And delete the existing code file from the Solution Explorer so that we tin can create our own class file to host on this web service.

Step 3

Now add a new class file to [WebService] and likewise a course for a user data type to ascertain the structure.

[WebSerivce] Course

User-ascertain information type for JSON and XML Stucture:

Step 4

Edit the Employee Grade and declare a belongings that we need to employ in the JSON and XML object.

Code:

1. public class  Employee
2. {
3. public int  Id { get ; set ; }
4. public string  Name { get ; set ; }
5. public int  Salary { go ; set ; }
6. }

Footstep 5

Now edit your .asmx file to define the CodeBehind and Form Properties.

Step 6

Side by side nosotros need to create a [WebService] form MyServiceClass and add all the namespaces commencement that are required.

Step 7

Write the [WebService] attribute over the grade name and create the [WebMethod].

1. GetEmployeeXML() for returning the data in XML.

   

2. GetEmployeeJSON() for returning the information in JSON.

   

Lawmaking:

1. using  System;
2. using  Organization.Collections.Generic;
3. using  Arrangement.Linq;
4. using  System.Web;
5. using  System.Web.Services;
6. using  Organization.Web.Script.Services;
7. using  System.Web.Script.Serialization;
8. [WebService]
9. public class  MyServiceClass
10. {
11.     [WebMethod]
12. public  Employee[] GetEmployessXML()
13.     {
14.         Employee[] emps=new  Employee[] {
15. new  Employee()
16.             {
17.                 Id=101,
18.                 Proper name="Nitin" ,

25.                 Salary=100000
26.             }
27.         };
28. return  emps;
29.     }
30.     [WebMethod]
31.     [ScriptMethod(ResponseFormat = ResponseFormat.Json)]
32. public string  GetEmployessJSON()
33.     {
34.         Employee[] emps =new  Employee[] {
35. new  Employee()

41. new  Employee()
42.             {
43.                 Id=102,
44.                 Name="Dinesh" ,
45.                 Salary=100000
46.             }
47.         };
48. return new  JavaScriptSerializer().Serialize(emps);
49.     }
50. }

Step 8

Build the application and view the output in a spider web browser.

There are 2 methods, one from the render ofJSON and the 2nd for the render ofXML event.
