Install
Microsoft.Practices.Unity.dll using package manager.
Install-Package Unity -Version
3.5.1404
Create an Interface :
Public interface ITestInterface
{
void Insert(string Name);
string GetName(string PassedName);
}
Create class :
Public class clsTestDI : ITestInterface
{
public void Insert(string Name)
{
}
public string GetName(string PassedName)
{
return "Hello " + PassedName;
}
}
Create Dependancy Injection registrattion
& resolver class :
using Microsoft.Practices.Unity
using System.Web.Mvc;
public class DIResolver
{
public void Initialise()
{
var container = new UnityContainer();
// Register Dependancy
RegisterTypes(container);
// Resolve Dependancy
DependencyResolver.SetResolver(new UnityDependencyResolver(container));
}
private void RegisterTypes(UnityContainer container)
{
// Register Dependancy
container.RegisterType<ITestInterface, clsTestDI>();
}
}
public class UnityDependencyResolver : IDependencyResolver
{
readonly IUnityContainer _container;
public UnityDependencyResolver(IUnityContainer container)
{
this._container = container;
}
public object GetService(Type serviceType)
{
try
{
return _container.Resolve(serviceType);
}
catch
{
return null;
}
}
public IEnumerable<object> GetServices(Type serviceType)
{
try
{
return _container.ResolveAll(serviceType);
}
catch
{
return new List<object>();
}
}
}
Register
dependency on App_Start event in Global.asax.
protected void Application_Start()
{
new DIResolver().Initialise();
}
Now you
are able to get access of class’ methods without creating instance (e.g. new
class () ;)
public class ProfileController : Controller
{
ITestInterface _Itest;
public ProfileController(ITestInterface ITest)
{
_Itest
= ITest;
}
//
// GET: /Profile/
public new ActionResult Profile()
{
string str = _Itest.GetName("Ajay");
return View();
}
}
