How to convert Object to List<string> in c#?
提问by Eric Yin
I have a List<string>in Model.
When I write a html helper, I can get the data from metadata.Model, which is an object
我有一个List<string>模型。当我编写一个html helper 时，我可以从中获取数据metadata.Model，它是一个对象
// this is from MVC3 (namespace System.Web.Mvc -> ModelMetadata), I did not write this
// Summary:
// Gets the value of the model.
//
// Returns:
// The value of the model. For more information about System.Web.Mvc.ModelMetadata,
// see the entry ASP.NET MVC 2 Templates, Part 2: ModelMetadata on Brad Wilson's
// blog
public object Model { get; set; }
My question is: how to get List<string>from an Object?
我的问题是：如何List<string>从Object?

If the underlying type of the objectvariable is List<string>, a simple cast will do:
如果object变量的基础类型是List<string>，一个简单的强制转换就可以了：
// throws exception if Model is not of type List<string>
List<string> myModel = (List<string>)Model;
or
或者
// return null if Model is not of type List<string>
List<string> myModel = Model as List<string>;
