使用使用剃刀語法諧音動態模型拋出

Question

我會用在很多不同的頁面，這將是不同的僅僅是參考模型（@model ...）相同的部分錯誤。我試着用「@model動態」這樣我就可以在觀看基準模型，但是lambda表達式是在我的部分被引用特定屬性都扔了以下錯誤：

"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" })

如何構建我的代碼或創建一個模型引用將動態工作，以便我可以在我的視圖頁面中引用每個特定的模型實例？我在網上嘗試了很多解決方案，到目前爲止沒有任何工作。以下是我的部分觀點。任何幫助將不勝感激！！！

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

Answer 1

檢查從您的操作方法或Razor視圖空

動態關鍵字在C＃4.0允許你做一個動態模型綁定

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

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

Answer 2

基於這條消息，我認爲你不能使用動態操作的「for」後綴的方法。

從來沒有使用過，但你可以嘗試generic form：

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

的語法說的表達，所以我相信它會支持點符號。

Answer 3

我想出了一個簡單的方法，如果你確定了基本的CSS和沒有什麼花哨。

您可以使用「EditForModel（）」在你的模型顯示的所有屬性，而不是「EditFor」每個屬性。在此之後，對於您不希望在視圖中顯示的每個屬性，可以在模型中添加「[ScaffoldColumn（false）]」，如下所示。感謝所有的建議！！！
