ViewResult does not implement IDisposable interface. Look at ASP.NET MVC source:
ViewResult.cs:
namespace System.Web.Mvc {
using System;
using System.Globalization;
using System.Text;
using System.Web.Mvc.Resources;
public class ViewResult : ViewResultBase {
...
ViewResultBase.cs:
namespace System.Web.Mvc {
using System;
using System.Diagnostics.CodeAnalysis;
public abstract class ViewResultBase : ActionResult {
...
ActionResult.cs:
namespace System.Web.Mvc {
public abstract class ActionResult {
public abstract void ExecuteResult(ControllerContext context);
}
}
UPDATED:
If you implement IDisposable interface in your class (derived from ViewResult) the Dispose() (IDisposable.Dispose()) will not be invoked by ASP.NET MVC framework.
If you want this behavior you can get it by extending ControllerActionInvoker. I believe you can do something like:
// warning: untested
public class DisposableControllerActionInvoker : ContollerActionInvoker
{
public override void InvokeActionResult(
ControllerContext controllerContext, ActionResult actionResult)
{
base.InvokeActionResult(controllerContext, actionResult);
var disposable = actionResult as IDisposable;
if(disposable != null)
{
disposable.Dispose();
}
}
}
You'll then need to get your ControllerActionInvoker added to the Controller, which you can do using a custom controller factory (there's probably a simpler way but I'm not familiar).
