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") 

 

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

2):Model 结构

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

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