Asp.net mvc 3 强类型视图绑定对象集合而不受ModelState影响

注意：我对ASP.NETMVC还比较陌生，所以我可能在这里采取了错误的方法；别客气，说吧

问题的总结是，如果我有一个视图是强类型的，它是一些模型对象的集合（比如，

IEnumerable

），我在视图上有多个表单-集合中的每个模型对象一个表单-然后发布其中任何一个表单都会导致所有表单反映编辑的特定对象的值

我理解它为什么这样做；如果您执行了一些服务器端验证或处理，但失败了，那么您不希望丢弃所有用户的更改，并恢复到以前存储在数据库中的内容。我不知道的是如何在表单绑定到多个对象的页面上管理这种行为

下面是一些演示该行为的示例代码。如果单击任何“保存”按钮，则所有三个表单都会反映所保存表单中的任何字段值。我希望这不会发生；我只想要保存以反映已发布表单变量的行。我对如何实现这一点只有粗略的想法，我不想碰巧编写代码

@文本框（“Field2”，obj.Field2）；
@文本框（“Field3”，obj.Field3）；
}
}

这是可行的，但很糟糕。我把它贴在这里，希望有人有更好的解决方案。如果我这样做，我基本上必须维护两组表单代码

我已经向DataObject添加了一个“主键”字段，我通过查看Request.QueryString来检查这是否是正在修改的项。如果是，我使用HTML帮助程序。如果不是，则使用普通的旧输入标记。但我不可能相信这是最好的处理方法
