new Microsoft.AspNetCore.Mvc.ViewFeatures.ViewDataDictionary : Microsoft.AspNetCore.Mvc.ViewFeatures.ViewDataDictionary -> Microsoft.AspNetCore.Mvc.ViewFeatures.ViewDataDictionary
Public Sub New (source As ViewDataDictionary)

参数

source
ViewDataDictionary

ViewDataDictionary 要从中复制初始值的实例。

注解

用于复制ViewDataDictionary实例和声明TypeModel的 不会更改,例如从ViewDataDictionary<TModel>实例复制到基ViewDataDictionary实例时。

不应将此构造函数用于可能设置为与 声明类型source不兼容的值的任何上下文Model中。
