在Asp.Net MVC中PartialView与EditorFor和DisplayFor的区别

相同之处：

PartialView, EditorFor 和 DisplayFor 都可以用作来实现页面的公共部分，其他页面可以根据需求来引用。

不同之处：

PartialView 是从Page的角度来处理，因此主 Page 和 PartialView 一般用相同的Model，这样做可以实现PartialView中所对应字段的编辑功能；如果PartialView使用的是主Page中Model的子Model，那么只能实现Partial View所对应Model的显示功能。

具体的引用方式为： @Html.Partial("~/Views/Shared/_ProductPartial.cshtml")        @Html.Partial("~/Views/Shared/_ProductPartial.cshtml", Model.Products)        @Html.RenderPartial("~/Views/Shared/_ProductPartial.cshtml")

EditorFor和DisplayFor是从Model的角度来处理，此时DisplayFor实现的是子Model的显示功能，EditorFor实现的是子Model的编辑功能。

具体的引用方式为： @Html.EditorFor(m => m.Products)         @Html.DisplayFor(m => m.Products)

下面将用一个简单的例子加以说明

1）： 工程代码结构

2）：Model 结构

    public class OrderModel
    {
        public string OrderId { get; set; }
        public string OrderName { get; set; }
        public List<ProductModel> Products { get; set; }
    }

    public class ProductModel
    {
        public string ProductId { get; set; }
        public string ProductName { get; set; }
        public double Price { get; set; }
    }

3）：PartialView

3.1）：Action Index

        public ActionResult Index()
        {
            OrderModel myOrder = GetMyOrder();
            return View(myOrder);
        }

        [HttpPost]
        public ActionResult Index(OrderModel model)
        {
            OrderModel myOrder = GetMyOrder();
            return View(myOrder);
        }

3.2）：Index.cshtml

@model MvcApplication2.Models.OrderModel

@{
    ViewBag.Title = "Index";
}

@using (Html.BeginForm())
{
    @Html.AntiForgeryToken()
    @Html.ValidationSummary(true)

    <div>
        <label>OrderName: </label>
        @Html.TextBoxFor(m => m.OrderName)
    </div>
    <div>
        @Html.Partial("~/Views/Shared/_ProductPartial.cshtml")
    </div>

    <input type="submit" value="Order" />
}

3.3）：_ProductPartial.cshtml

@model MvcApplication2.Models.OrderModel

<div>
    @foreach (var item in Model.Products)
    {
        <div>
            <label>ProductName: </label>
            <input value="@item.ProductName" />
        </div>

        <div>
            <label>Price: </label>
            <input value="@item.Price" />
        </div>
    }
</div>

4）：EditorFor

4.1）：Action IndexForEditor

        public ActionResult IndexForEditor()
        {
            OrderModel myOrder = GetMyOrder();
            return View(myOrder);
        }

        [HttpPost]
        public ActionResult IndexForEditor(OrderModel model)
        {
            OrderModel myOrder = GetMyOrder();
            return View(myOrder);
        }

4.2）：IndexForEditor.cshtml

@model MvcApplication2.Models.OrderModel

@{
    ViewBag.Title = "IndexForEditor";
}

@using (Html.BeginForm())
{
    @Html.AntiForgeryToken()
    @Html.ValidationSummary(true)

    <div>
        <label>OrderName: </label>
        @Html.TextBoxFor(m => m.OrderName)
    </div>
    <div>
        @Html.EditorFor(m => m.Products)
    </div>

    <input type="submit" value="Order" />
}

4.3）：ProductModel.cshtml

@model MvcApplication2.Models.ProductModel

<div>
    @Html.LabelFor(m => m.ProductName)
    @Html.TextBoxFor(m => m.ProductName)
</div>
<div>
    @Html.LabelFor(m => m.Price)
    @Html.TextBoxFor(m => m.Price)

        }

        [HttpPost]

            order.OrderId = "o001";
            order.OrderName = "Order001";

            List<ProductModel> productList = new List<ProductModel>();
            ProductModel product001 = new ProductModel();
            product001.ProductId = "p001";
            product001.ProductName = "Product001";
            product001.Price = 1000.00;
            ProductModel product002 = new ProductModel();
            product002.ProductId = "p002";
            product002.ProductName = "Product002";
            product002.Price = 2000.00;
