Question

我有两张桌子。第一个表product id包含name，Department_id和Departments列。第二个表Department id包含name和import org.apache.commons.lang3.builder.ReflectionToStringBuilder; import org.apache.commons.lang3.builder.ToStringStyle; ... return ReflectionToStringBuilder.toString(this, ToStringStyle.NO_CLASS_NAME_STYLE);列。

我想创建一个页面以插入Product表中的Products详细信息，我希望在此页面上应该使用Departments名称填充一个组合框。

Answer 1

虽然我们不清楚你的问题。但不知何故，我想出了你想要的东西..

模型类

public class Product
{
    public int ProductId { get; set; }

    public string ProductName { get; set; }
}

public class Departments
{
    public int DepartmentID{get;set;}
    public string DepartmentName {get;set;}
}

<强>控制器

public class HomeController : Controller
{
    [HttpGet]
    public ActionResult Index()
    {
          List<Departments> deps = new List<Departments>();

        deps.Add(new Departments() {DepartmentID=1, DepartmentName="IT"});
        deps.Add(new Departments() { DepartmentID = 2, DepartmentName = "HR" });

        ViewBag.lstDeps = deps;

        return View(new Product());
    }

查看

@model HelloWorldMvcApp.Product @{ Layout = null; } @{ IEnumerable<HelloWorldMvcApp.Departments> CDrop = ViewBag.lstDeps; List<SelectListItem> selectList = new List<SelectListItem>(); foreach (var c in CDrop) { SelectListItem i = new SelectListItem(); i.Text = c.DepartmentName.ToString(); i.Value = c.DepartmentID.ToString(); selectList.Add(i); } } <!DOCTYPE html>  <html lang="en"> <head> <meta charset="utf-8"> </head> <body> <div class="container"> <div class="col-md-6 col-md-offset-3"> <h1>Hello Stranger</h1> @Html.DropDownList("DEpartments", new SelectList(selectList, "Value","Text")) @using (Html.BeginForm()) { <div class="form-group"> @Html.LabelFor(m => m.ProductName) @Html.TextBoxFor(model => model.ProductName, new {@class="form-control"}) </div> } <br/><br/> </div> </div>  <script src="//ajax.googleapis.com/ajax/libs/jquery/1.11.0/jquery.min.js"></script> <script src="//netdna.bootstrapcdn.com/bootstrap/3.1.1/js/bootstrap.min.js"></script> <script src="//ajax.aspnetcdn.com/ajax/jquery.validate/1.11.1/jquery.validate.min.js"></script> <script src="//ajax.aspnetcdn.com/ajax/mvc/4.0/jquery.validate.unobtrusive.min.js"></script> </body> </html>

Answer 2

您可以创建一个组合Product和Departments的模型，并将其从控制器传递到视图。

例如：

public class CompositeModel
{
     public Product product { get; set;}
     public Department department { get; set;}
}

希望这会有所帮助。
