Question

Using MVCContrib you can easily do RedirectToAction calls such as

this.RedirectToAction( c => c.List() );

where List is an action result in said controller. Is there a way to do the same but using the “View” method instead? I.E

this.View( c => c.List(), viewModel );

Here’s a trivial but complete example:

[HttpGet]
public ActionResult Profile()
{
    return View( new ProfileViewModel() )
}

[HttpPost]
public ActionResult Profile( ProfilePostModel postModel )
{
    if( !ModelState.IsValid )
        return this.View( c => c.Profile(), postModel.MapToViewModel() );
    _service.Save(postModel.MapToDtoObject() );
    return this.RedirectToAction( c => c.SomeOtherAction() );
}

I’ve been searching around and haven’t found anything relevant.. Thanks!

I don’t know if such method exists in MVCContrib but it would be trivial to write one:

public static class ControllerExtensions
{
    public static ViewResult View<T>(
        this T controller, 
        Expression<Func<T, ActionResult>> expression, 
        object model
    ) where T : Controller
    {
        var mce = expression.Body as MethodCallExpression;
        if (mce == null)
        {
            throw new NotSupportedException();
        }
        var result = new ViewResult();
        result.ViewName = mce.Method.Name;
        result.ViewData.Model = model;
        return result;
    }
}
