如何更新的IEnumerable＆LT;＆MyObject的GT;在MVC？ [英] How to updating IEnumerable<MyObject> in mvc?

问题描述

我有型号为MyObject，然后在视图中我有

I have model MyObject and then in the view I have

@model IEnumerable<MyProject.Models.MyObject>

和再往形式：

@using(Html.BeginForm())
{
    @foreach(MyObject m in Model)
    {
        @Html.TextboxFor(x => x.Name)
    }
}

<input type="submit" value="modify" />

我想在我的控制器这样获得的：

I am trying to get this in my controller like this:

[HttpPost]
public void Update(MyObject _myOject)
{
}

当我看到源$ C ​​$ C，所有名称重复和_myObject不正确填充

When I see the source code, all name is repeated and _myObject is not correctly populated

如何更新对象的列表，并在一次性全部储存在MVC？

how do I update a list of objects and save them all at once in MVC?

推荐答案

您的操作方法是等待名为_myObject一个参数。而你想更新的对象列表

You action method is waiting for a single parameter named _myObject. And you want to update list of objects

尝试是这样的：

@using(Html.BeginForm(......))
{
    int i = 0;
    foreach(MyObject m in Model)
    {
        @Html.TextBox(string.Format("_myObjects[{0}].Name", i), m.Name)
        i++;
    }

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

和您的操作方法应该是这样的：

and your action method should look like that:

[HttpPost]
public void Update(IList<MyObject> _myObjects)
{
}

，那么你就可以立刻更新此列表

then you will be able to update this list at once
