What is HttpGet and what is AcceptVerbs(HttpVerbs.Get) ?
Example:
[AcceptVerbs(HttpVerbs.Get)]
public ActionResult GetStatesByCountryId(string countryId)
{
return ....
}
Another example:
[HttpGet]
public ActionResult GetStatesByCountryId(string countryId)
{
return ....
}
What are the features between them?
There is no difference in these two code snippets, they have the same purpose, so the method only accepts requests from verb % with%, in fact one is abbreviation of the other. In the source HttpGetAttribute is very clear that it is the abbreviation for AcceptVerbsAttribute :
Code < HttpGetAttribute :
using System.Reflection;
namespace System.Web.Mvc
{
[AttributeUsage(AttributeTargets.Method, AllowMultiple = false, Inherited = true)]
public sealed class HttpGetAttribute : ActionMethodSelectorAttribute
{
private static readonly AcceptVerbsAttribute _innerAttribute =
new AcceptVerbsAttribute(HttpVerbs.Get);
public override bool IsValidForRequest(ControllerContext controllerContext,
MethodInfo methodInfo)
{
return _innerAttribute
.IsValidForRequest(controllerContext, methodInfo);
}
}
}

One advantage of using GET is that it can contain more than one type of AcceptVerbs() , example :
[AcceptVerbs(HttpVerbs.Get | HttpVerbs.Post)]
or
[AcceptVerbs("GET", "POST")]
so the method accepts requests from verb verb or GET in the example
POST , [HttpGet] or [HttpPost] , etc.) the method accepts by Remarks: standard [AcceptVerbs("POST")] verb
