如何使用 Entity Framework 在 MVC 中显示来自存储过程的 return 数据

How show the return data from stored procedure in MVC using Entity Framework

我是 MVC 的新手,Entity Framework 如果这是一个简单的问题,请原谅。

我正在开发一个简单的项目 (MVC5-EF6),它根据名字和姓氏以及 return 客户信息查询客户 table。我正在使用 Entity Framework 调用存储过程以获取 return 数据。

我已经导入了数据库,一切正常。我唯一不确定的是,我应该如何使用视图显示 return 数据?

我试图将数据放入我创建的模型中,但是当我调试数据时,虽然我不确定它应该是什么 return 在这一行中:

 return View(customerModel);

因为我收到此错误:

The model item passed into the dictionary is of type 'CustomerPortal_MVC.Models.CustomerModel', but this dictionary requires a model item of type 'CustomerPortal_MVC.Customer'.

这是调用存储过程的方法:

public ActionResult Details()
{
    using (var context = new CustomerPortalEntities())
    {
        var customers = context.Search_Customer_By_Name("NONA", "WHITE", null);
        CustomerModel customerModel = new CustomerModel();

        foreach (var item in customers)
        {
            customerModel.Account_Number = item.Account_Number;
            customerModel.First_Name = item.First_Name;
            customerModel.Last_Name = item.Last_Name;
            customerModel.Payment_in = item.Payment_in;
        }

        return View(customerModel);
    }
}

这是模特:

public class CustomerModel
{
    public int Customer_ID { get; set; }
    public string Account_Number { get; set; }
    public string First_Name { get; set; }
    public string Last_Name { get; set; }
    public string Payment_in { get; set; }
}

这是自动填充的视图代码。

 @model CustomerPortal_MVC.Customer

 @{
  ViewBag.Title = "Details";
   }

<h2>Details</h2>

<div>
<h4>Customer</h4>
<hr />
<dl class="dl-horizontal">
    <dt>
        @Html.DisplayNameFor(model => model.Account_Number)
    </dt>

    <dd>
        @Html.DisplayFor(model => model.Account_Number)
    </dd>

    <dt>
        @Html.DisplayNameFor(model => model.First_Name)
    </dt>

    <dd>
        @Html.DisplayFor(model => model.First_Name)
    </dd>

    <dt>
        @Html.DisplayNameFor(model => model.Middle_Name)
    </dt>

    <dd>
        @Html.DisplayFor(model => model.Middle_Name)
    </dd>

    <dt>
        @Html.DisplayNameFor(model => model.Last_Name)
    </dt>

    <dd>
        @Html.DisplayFor(model => model.Last_Name)
    </dd>

    <dt>
        @Html.DisplayNameFor(model => model.Password)
    </dt>

    <dd>
        @Html.DisplayFor(model => model.Password)
    </dd>

    <dt>
        @Html.DisplayNameFor(model => model.isRegistered)
    </dt>

    <dd>
        @Html.DisplayFor(model => model.isRegistered)
    </dd>

    <dt>
        @Html.DisplayNameFor(model => model.isActivated)
    </dt>

    <dd>
        @Html.DisplayFor(model => model.isActivated)
    </dd>

    <dt>
        @Html.DisplayNameFor(model => model.isActive)
    </dt>

    <dd>
        @Html.DisplayFor(model => model.isActive)
    </dd>

    <dt>
        @Html.DisplayNameFor(model => model.isLocked)
    </dt>

    <dd>
        @Html.DisplayFor(model => model.isLocked)
    </dd>

    <dt>
        @Html.DisplayNameFor(model => model.Account_Payment_Status)
    </dt>

    <dd>
        @Html.DisplayFor(model => model.Account_Payment_Status)
    </dd>

    <dt>
        @Html.DisplayNameFor(model => model.unsuccessful_login_count)
    </dt>

    <dd>
        @Html.DisplayFor(model => model.unsuccessful_login_count)
    </dd>

    <dt>
        @Html.DisplayNameFor(model => model.Username)
    </dt>

    <dd>
        @Html.DisplayFor(model => model.Username)
    </dd>

    <dt>
        @Html.DisplayNameFor(model => model.Last4SSN)
    </dt>

    <dd>
        @Html.DisplayFor(model => model.Last4SSN)
    </dd>

    <dt>
        @Html.DisplayNameFor(model => model.Create_Date)
    </dt>

    <dd>
        @Html.DisplayFor(model => model.Create_Date)
    </dd>

    <dt>
        @Html.DisplayNameFor(model => model.Modified_Date)
    </dt>

    <dd>
        @Html.DisplayFor(model => model.Modified_Date)
    </dd>

    <dt>
        @Html.DisplayNameFor(model => model.Account_Status)
    </dt>

    <dd>
        @Html.DisplayFor(model => model.Account_Status)
    </dd>

    <dt>
        @Html.DisplayNameFor(model => model.Salt)
    </dt>

    <dd>
        @Html.DisplayFor(model => model.Salt)
    </dd>

</dl>
</div>
<p>
@Html.ActionLink("Edit", "Edit", new { id = Model.Customer_ID }) |
@Html.ActionLink("Back to List", "Index")

解法:

我把视图改成这样:

 @model CustomerPortal_MVC.Models.CustomerModel

@{
     ViewBag.Title = "Details";
}

 <h2>Details</h2>

 <div>
<h4>Customer</h4>
<hr />
<table>


    <tr>
        <td>
            @Html.DisplayFor(model => model.First_Name)
             @Html.DisplayFor(model => model.Account_Number)
        </td>

    </tr>

</table>

</div>
   <p>
    @Html.ActionLink("Edit", "Edit", new { id = Model.Customer_ID }) |
@Html.ActionLink("Back to List", "Index")
</p>

问题是您的视图期望的类型与您返回的类型不同。

在您的视图顶部,您可能有一行如下所示:

@model CustomerPortal_MVC.Customer

应该是:

@model CustomerPortal_MVC.Models.CustomerModel

无论您传递给 View() 的什么类型,都应该与视图期望的类型相同。这是优于 ViewBag 的优势之一,因为您可以对模型进行类型检查。
