Question

使用MVC 5。我正在尝试获取几种视图中的任何一种，我将通过ajax将其注入到Div中。我正在使用在SO上找到的类，该类将我限制在我从中调用方法的控制器上。

我需要能够为该方法提供我想要的任何类。有什么办法可行吗？。

这就是我所拥有的。

public static string RenderView(this Controller controller, string viewName, object model)
{
        return RenderView(controller, viewName, new ViewDataDictionary(model));
}


public static string RenderView<TModel>(this Controller controller, string viewName, TModel model, bool partial = false)
{
    var controllerContext = controller.ControllerContext;
    controllerContext.Controller.ViewData.Model = model;
    //viewName = "List";
    //var viewResult = partial ? ViewEngines.Engines.FindPartialView(controllerContext, viewName) : ViewEngines.Engines.FindView(controllerContext, viewName, null);
    StringWriter stringWriter;

    using (stringWriter = new StringWriter())
    {
        var viewResult = ViewEngines.Engines.FindView(controllerContext, viewName, null);
        var viewContext = new ViewContext(controllerContext, viewResult.View, controllerContext.Controller.ViewData, controllerContext.Controller.TempData, stringWriter);

        viewResult.View.Render(viewContext, stringWriter);
        viewResult.ViewEngine.ReleaseView(controllerContext, viewResult.View);

        return stringWriter.GetStringBuilder().ToString();
    }
}

从控制器UserAndPersonController中，我调用此方法，然后尝试获取返回ajax调用所需的任何View并将其放置在特定的Div中。

public string GetView(string viewName, string request)
{
    Object obj = new Object(); 
    // Get the various Designations a Person can have
    if (request.Contains("User"))
    {
        obj = new { PersonUserModel = "Catalyst.Mvc.Models.PersonUserModel" };
    }
    else if (request.Contains("Driver"))
    {
        obj = new { DriverViewModel = "Models.DriverViewModel" };
    }
    else if (request.Contains("Debtor"))
    {
        obj = new { DebtorViewModel = "Models.DebtorViewModel" };
    }

    // ?? How do I get any Controller context , each must match the respective models 
    string viewHTML = this.RenderView( "List", obj);
    return viewHTML;
}

我也从viewResult.view.render（viewContext，stringWriter）;中得到一个错误。线，无论我尝试通过哪个模型。

System.InvalidOperationException：'传递到字典中的模型项的类型为'<> f__AnonymousType14`1 [System.String]'，但是此字典需要类型为'Catalyst.Mvc.Models.PersonUserModel'的模型项。 '

如何获取任何MVC控制器的controllercontext？
