1.前言
本来今天是想发那篇关于在Web API中关于路由的选择，但那一份是在公司翻译的，文件也在公司里。然后自己也比较感兴趣一些比较偏的知识。就像今天这一篇。在翻译的过程中，很多的文字自己感觉到十分的生硬，希望以后在自己看懂文章后，用文字将自己的理解表达出来，相信这样会更好。
2. 开始
在MVC中，相信大家都使用过ViewData或ViewBag（ViewBag是ViewData的一层封装），还一个用于在控制器向视图传递数据的方法-TempData，那我们能不能使用类似ViewBag包装ViewData的方式，使用TempBag实现动态查找值。我们可以创建一个类，如下
public class TempBag: DynamicObject
{
TempDataDictionary tempData = null; public TempBag(TempDataDictionary tempdata)
{
this.tempData = tempdata;
} public override bool TryGetMember(GetMemberBinder binder, out object result)
{
try
{
//如果能找到相应的Key
if (tempData.Keys.Where(k => k == binder.Name).Count() > )
{
result = tempData[binder.Name];
return true;
}
else
{
result = "找不到值";
return false;
}
}
catch
{
result = "找不到值";
return false;
}
} public override bool TrySetMember(SetMemberBinder binder, object value)
{
try
{
tempData[binder.Name] = value;
return true;
}
catch
{
return false;
}
}
}
DynamicObject类位于System.Web.Mvc下，使用DynamicObject能够创建自己的动态对象。自己的类需要继承DynamicObject类，重写里面的三个方法：TrySetMember、TryGetMember、TryInvokeMember，前面两个方法用于设置和获取属性的实现，最后一个方法用于动态方法的调用，这里就不作介绍。
3.控制器中代码
public class TempDataController : Controller
{ dynamic tempBag = null; public TempDataController()
{
tempBag = new TempBag(TempData);
} public ActionResult Index()
{
tempBag.Message = "一个很好的结果";
return View();
} }
在实例化控制器的时候，将它的一个动态对象实例化为我们自己定义的类的类型。控制器的构造函数中，传递TempData作为参数，那么我们在自己类中重写的两个方法分别对应为TempData设置和获取值。
4.在视图面的代码
@{
Layout = null;
dynamic tempBag = new TempBag(TempData);
}
<!DOCTYPE html>
<html>
<head>
<meta name="viewport" content="width=device-width" />
<title>Index</title>
</head>
<body>
<div>
<p>@@tempBag.Message的值为: @tempBag.Message</p>
<p>@@TempData["Message"]的值为: @TempData["Message"]</p>
</div>
</body>
</html>
如果没差错，那显示的结果如下图
