Question

我正在传递ViewBag，

 var forms = SqlMapper.Query(con, "getDetails", param, commandType: CommandType.StoredProcedure);

 ViewBag.myForm = forms;

这种形式＆＃39;包含VehicleType，VehicleName，VehiclePrice等值我正在使用循环显示那些视图，

  @foreach (var frm in ViewBag.myForm)
  {
  <div class="form-group">

  <label for="exampleInputEmail1">@frm.VehicleType</label>
  <label for="exampleInputEmail1">@frm.VehicleName</label>
  <label for="exampleInputEmail1">@frm.VehiclePrice</label>
  </div>
  }

这很好用。现在我想在标题中显示VehicleType。而且我不想再次循环ViewBag来获取VehicleType。 VehicleType与列表相同。就好像我得到了汽车一样。作为VehicleType，那么对于那个ViewBag，＆＃39; Car＆＃39;是唯一的VehicleType。如何在不循环ViewBag的情况下阅读VehicleType？感谢

为了更多地了解数据，

Vehicle Type | Name | Price
Car          | Ford | 1000000
Car          | Audi | 1500000
Car          | Chev.| 1250000
Car          | Volks| 1246000

我想显示车辆类型

 <div class="box-header with-border">
                        <h3 class="box-title">@ViewBag.myForm ----- VehicleType</h3>
                    </div>

Answer 1

您应该使用模型而不是ViewBag。这样您就不必循环遍历列表以获得一个VehicleType

<强> Vehicle.cs

public class Vehicle
{
    public int VehicleID {get; set;}
    public string VehicleType {get; set;}
    public string VehicleName {get; set;}
    public double VehiclePrice {get; set;}
}

<强>控制器

var forms = SqlMapper.Query(con, "getDetails", param, commandType: CommandType.StoredProcedure);
List<Vehicle> vehicleList = new List<Vehicle>();
vehicleList = forms;

查看

@model IEnumerable<ProjName.Models.Vehicle> @Html.DisplayFor(model => model.ElementAt(0).VehicleType) @foreach (var frm in Model) { <div class="form-group"> <label for="exampleInputEmail1">@frm.VehicleName</label> <label for="exampleInputEmail1">@frm.VehiclePrice</label> </div> }

从ViewBag中选择单个值
