适用于所有PartialViews的自定义ActionResult等效模型
适用于所有PartialViews的自定义ActionResult等效模型
提问于 2016-01-10 22:01:11
我创建了下面的自定义ActionResult，它返回多个分部视图。
public class MultiplePartialViewsResult : ActionResult
{
private const string Separator = "-";
private PartialViewResult[] _partialViews;
public MultiplePartialViewsResult(params PartialViewResult[] partialViews)
{
_partialViews = partialViews;
}
public override void ExecuteResult(ControllerContext context)
{
foreach (var partialView in _partialViews)
{
partialView.ExecuteResult(context);
context.HttpContext.Response.Output.Write(Separator);
}
}
}然后我按如下方式使用它：
return new MultiplePartialViewsResult(
PartialView("~/Views/RowSumView.cshtml", new List<double>() { 1.0 }),
PartialView("~/Views/ColumnSumView.cshtml", new List<double>() { 2.0 }));但是如果我将断点放在MultiplePartialViewsResult的构造函数中，我会发现两种情况下的模型都等于2.0，它用数组中指定的最后一个模型覆盖所有的模型。
尝试在方法中创建耦合变量并将其赋值给PartialViews。然后你会注意到他们都共享相同的模型。

您可以使用新的 ViewData / ViewData.Model实例以以下方式初始化对象(对我来说很好)：
return new MultiplePartialViewsResult(
//PartialView("~/Views/RowSumView.cshtml", new List<double>() { 1.0 }),
//PartialView("~/Views/ColumnSumView.cshtml", new List<double>() { 2.0 })
new PartialViewResult() { ViewName = "~/Views/RowSumView.cshtml", ViewData = new ViewDataDictionary() { Model = new List<double>() { 1.0 } } },
new PartialViewResult() { ViewName = "~/Views/ColumnSumView.cshtml", ViewData = new ViewDataDictionary() { Model = new List<double>() { 2.0 } } }
);自定义操作结果：
public class MultiplePartialViewsResult : ActionResult {
private const string Separator = "-";
private PartialViewResult[] _partialViews;
public MultiplePartialViewsResult(params PartialViewResult[] partialViews) {
_partialViews = partialViews;
}
public override void ExecuteResult(ControllerContext context) {
foreach(var partialView in _partialViews) {
partialView.ExecuteResult(context);
context.HttpContext.Response.Output.Write(Separator);
}
}
}控制器：
public ActionResult Index() {
return View();
}
public ActionResult FakeAction() {
return new MultiplePartialViewsResult(
//PartialView("~/Views/RowSumView.cshtml", new List<double>() { 1.0 }),
//PartialView("~/Views/ColumnSumView.cshtml", new List<double>() { 2.0 })
new PartialViewResult() { ViewName = "~/Views/RowSumView.cshtml", ViewData = new ViewDataDictionary() { Model = new List<double>() { 1.0 } } },
new PartialViewResult() { ViewName = "~/Views/ColumnSumView.cshtml", ViewData = new ViewDataDictionary() { Model = new List<double>() { 2.0 } } }
);
}视图：
指数：
@Html.Action("FakeAction")ColumnSumView.cshtml / RowSumView.cshtml:
@model List<double>
<ul>
@foreach(double item in Model) {
<li>@item</li>
}
