有没有办法为匿名类添加额外的属性(或创建具有额外属性的新实例)？
string cssClasses = "hide";
object viewData = new { @class = cssClasses };
if (suppliedId != null)
{
// add an extra id property to the viewData somehow...
// desired end result is { @id = suppliedId,@class = cssClasses }
}
// ... code will be passing the viewData as the additionalViewData parameter in asp.mvc's .EditorFor method
解决方法
不,你不能这样做.但是,您可以重新定义它：
dynamic viewData = new { @class = cssClasses };
if (suppliedId != null)
{
viewData = new { @class = viewData.@class,yourExtra = Property };
}
请注意,我将其更改为动态.这样您就可以编辑属性而无需强制转换为动态.
