如何在父部分视图中访问模型数据

I have one controller which will pass data to view Index.cshtml

我有一个控制器,它将传递数据以查看Index.cshtml

public ActionResult Index()
    {
        var empId = @User.Identity.Name;
        var empDetails = empRepository.GetEmployeeDetails(empId);
        var emp = new UserViewModel {EmployeeDetail = empDetails};
        return View(emp);
    }

Layout of view Index.cshtml is Partialview _Layout.cshtml

视图的布局Index.cshtml是Partialview _Layout.cshtml

@model HRM.Areas.EmployeeDetails.Models.UserViewModel
@{
       ViewBag.Title = "Index";
       Layout = "~/Areas/EmployeeDetails/Views/Shared/_Layout.cshtml";
 }

 <div>Hello</div>

I want to access the data which I passed from controller action to Index.cshtml in _Layout.cshtml.

我想访问从控制器操作传递到_Layout.cshtml中的Index.cshtml的数据。

Is there any way to do this ?

有没有办法做到这一点?

Your question is not clear on how you want to access the values so i'm making an assumption here:

你的问题不明确你想如何访问这些值,所以我在这里做一个假设:

If you want to include data from a view in a rendering from your layout page you can use the RenderSection method.

如果要在布局页面的渲染中包含视图中的数据,可以使用RenderSection方法。

Layout Page:

@RenderSection("ViewSection", false)

View Page:

@section ViewSection {
<div>
    <label>Emp Name:</label>
    @model.EmpDetails.Name    
</div>

}

When your Layout is rendered it'll look for a section in your view that matches and render it. Passing a false as the 2nd param tell the Layout that the section is not required.

渲染Layout时,它会在视图中查找匹配并呈现它的部分。传递false作为第二个参数告诉布局该部分不是必需的。

Your question is not quite clear to me:/

您的问题对我来说不太清楚:/

My assumption -> If you change your code to look like this:

我的假设 - >如果您将代码更改为如下所示:

 public ActionResult Index()
        {
            var empId = @User.Identity.Name;
            var empDetails = empRepository.GetEmployeeDetails(empId);
            var emp = new UserViewModel { EmployeeDetail = empDetails };

            ViewBag.UserViewModel = emp;

            return View(emp);
        }

on the Layout page you can access your data:

在布局页面上,您可以访问您的数据:

@if (ViewBag.UserViewModel != null)
{
    //do sth with ViewBag.UserViewModel here
    //for example:
    @Html.Partial("_UserView",ViewBag.UserViewModel)

}

If you explain in details what you want to achive it will be easier for us to give you the right answer.

如果您详细解释您想要实现的目标,我们将更容易为您提供正确的答案。

You can access the data in the model like this:

您可以像这样访问模型中的数据:

@Model.EmployeeDetail ...
