How to create Web Api in Asp.net web forms 4.0/4.5
2) Add Web Api Controller class
Name it as ValuesController.cs VS 2012 adds ValuesController1.cs remove 1 otherwise it won't work. i.e ApiController controller class must end with "Controller"
using System;
using System.Collections.Generic;
using System.Linq;
using System.Net;
using System.Net.Http;
using System.Web.Http;
namespace WebApplication3
{
public class ValuesController : ApiController
{
// GET api/<controller>
public IEnumerable<string> Get()
{
return new string[] { "value1", "value2" };
}
// GET api/<controller>/5
public string Get(int id)
{
return "value";
}
// POST api/<controller>
public void Post([FromBody]string value)
{
}
// PUT api/<controller>/5
public void Put(int id, [FromBody]string value)
{
}
// DELETE api/<controller>/5
public void Delete(int id)
{
}
}
}
3) Add Global.asax global class.
in Application_Start
add following namespaces( These Assemblies will be referenced automatically whenever u add Web Api Control class)
using System.Web.Http;
using System.Web.Routing;
4) in Application_start Global.asax
Add Routing information for WEB APIS.
4.1 "WebApi/{controller}" in this --> WebApi is a optional constant. User has his own choice of specifying it or not.
4.2 {contoller} is a keyword.(must be specified)
4.3 "Defaultapi" -> Routing table is dictionary so it must be unique across the web application.
user has choice of specify any value here.
Here is the code.
namespace WebApplication3
{
public class Global : System.Web.HttpApplication
{
protected void Application_Start(object sender, EventArgs e)
{
GlobalConfiguration.Configuration.Routes.MapHttpRoute("Defaultapi",
"WebApi/{controller}");
}
}
That's it
Just run the Web Application
Here is the URL to access WebAPI.
http://localhost:8899/WebApi/Values
1)change port number
2)WebApi constant specified in Routing tag.
if Routing url is "{controller}" then to access WebAPI through url
http://localhost:8899/Values
Note: Controller class can be Anywhere in the Web Application. i.e it can be even in nested folders. But Controller name should be unique unless specified by different routing values.
