使用使用剃刀语法谐音动态模型抛出

Question

我会用在很多不同的页面，这将是不同的仅仅是参考模型（@model ...）相同的部分错误。我试着用“@model动态”这样我就可以在观看基准模型，但是lambda表达式是在我的部分被引用特定属性都扔了以下错误：

"An expression tree may not contain a dynamic operation"

caused by the following reference to model:

@Html.LabelFor(model => model.Name, htmlAttributes: new { @class = "control-label col-md-2" })

如何构建我的代码或创建一个模型引用将动态工作，以便我可以在我的视图页面中引用每个特定的模型实例？我在网上尝试了很多解决方案，到目前为止没有任何工作。以下是我的部分观点。任何帮助将不胜感激！！！

@model CreativeNamingConvention.Models.Domain.CreativeOps 

@{ 
ViewBag.Model = Model; 
ViewBag.Title = "Edit Creative Ops Field"; 
} 

@Html.Partial("~/Views/Templates/editBody.cshtml", Model)

检查从您的操作方法或Razor视图空

动态关键字在C＃4.0允许你做一个动态模型绑定

dynamic viewModel = new ExpandoObject(); 
    viewModel.TestString = "This is a test string"; 

return View(viewModel); for more in refer the below link

Answer 2

基于这条消息，我认为你不能使用动态操作的“for”后缀的方法。

从来没有使用过，但你可以尝试generic form：

@Html.Label("Name", "Name Label", htmlAttributes: new { @class = "control-label col-md-2" }) 

的语法说的表达，所以我相信它会支持点符号。

Answer 3

我想出了一个简单的方法，如果你确定了基本的CSS和没有什么花哨。

您可以使用“EditForModel（）”在你的模型显示的所有属性，而不是“EditFor”每个属性。在此之后，对于您不希望在视图中显示的每个属性，可以在模型中添加“[ScaffoldColumn（false）]”，如下所示。感谢所有的建议！！！
