c# - 如何在请求过滤器的 ViewResult 上设置 View 模型？

Question

我制作了一个 MVC 项目，我想将模型设置为来自过滤器的 View 。

但是我不知道，我该怎么做。

模型:

public class TestModel
{
    public int ID { get; set; }
    public string Name { get; set; }
}

Controller :

[CustomFilter(View = "../Test/Test")]//<===/Test/Test.cshtml
public ActionResult Test(TestModel testModel)//<===Model from Page
{
      //the Model has Value!!
       // if has some exception here
        return View(model);//<=====/Test/Test.cshtml
}

过滤器(只是演示):

public override void OnActionExecuting(ActionExecutingContext filterContext){
     ViewResult vr = new System.Web.Mvc.ViewResult()
     {
            ViewName = this.View,//<======/Test/Test.cshtml
            ViewData = filterContext.Controller.ViewData                             
      };
      //How can I set Model here?!!
      vr.Model = ???? //<========the Model is only get
      filterContext.Result = vr;
}

更改过滤器扩展到 HandleErrorAttribute

  ViewResult vr = new System.Web.Mvc.ViewResult()
     {
            ViewName = this.View,//<======/Test/Test.cshtml
            ViewData = new ViewDataDictionary(filterContext.Controller.ViewData)
            {
                //I want get testModel from Action's paramater
                //the filter extends HandleErrorAttribute
                Model = new { ID = 3, Name = "test" }// set the model
            }                             
      };

编辑结束

测试/测试.chtml

@model TestModel
<h2>Test</h2>
@Model //<=====model is null

当我请求时

http://localhost/Test/Test?ID=3&Name=4

测试页获取不到模型

ViewResult vr = new System.Web.Mvc.ViewResult
    {
        ViewName = this.View, //<======/Test/Test.cshtml
        ViewData = new ViewDataDictionary(filterContext.Controller.ViewData)
            {
                Model = // set the model
            }
    };
