c# - ASP.NET View 和模型，一个小问题

Question

亲爱的，

请你帮我理解非常简单的事情

我的类(class)有模特:

public class VendorAssistanceViewModel
{
    public string Name { get; set; }
    public bool Checked { get; set; }
}
public partial class CSModel : IEntity
{
    public CSModel()
    {

        VendorAssistances = new[]
        {
        new VendorAssistanceViewModel { Name = "DJ/BAND" },
        new VendorAssistanceViewModel { Name = "Officiant" },
        new VendorAssistanceViewModel { Name = "Florist" },
        new VendorAssistanceViewModel { Name = "Photographer" },
        new VendorAssistanceViewModel { Name = "Videographer" },
        new VendorAssistanceViewModel { Name = "Transportation" },
        }.ToList();
    }


    public IList VendorAssistances { get; set; }

我有看法:

@model IEnumerable<CSTS.Models.CSModel>

 //some html code...

我想知道如何使用 VendorAssistances 显示模型中的复选框数组？我知道这很简单，我看了很多文档，还是看不懂

谢谢!

更新

我试着做以下事情:

1. 控制

            public override ActionResult Index(int pageNumber, int pageSize, string   nothing)
     {
   
     List<VendorAssistanceViewModel> VendorAssistances = new[]
   {
   new VendorAssistanceViewModel { Name = "DJ/BAND" },
   new VendorAssistanceViewModel { Name = "Officiant" },
   new VendorAssistanceViewModel { Name = "Florist" },
   new VendorAssistanceViewModel { Name = "Photographer" },
   new VendorAssistanceViewModel { Name = "Videographer" },
   new VendorAssistanceViewModel { Name = "Transportation" },
   }.ToList();
   

我已将 Watch 添加到 VendorAssistances 并插入断点，并且所有时间 tihs 对象都是 NULL

为什么？

Answer 1

您只需遍历 Model.VendorAssistances 并为每个 VendorAssistanceViewModel 发出 html 代码。您可以使用此代码:

@foreach(var model in Model)
{
    for(int i=0; i < model .VendorAssistances.Count; i++)
    {
        @Html.CheckBoxFor(x => model.VendorAssistances[i].Name)
    }
}

另请阅读 this可以帮助您理解如何将生成的数组发布到操作的问题。
