c# - Type conversion and typeof -

After

I have made the following declaration in C #

  Personal IDictionary & LT; ViewModelBase, Type & gt; _routingDictionary;  

With the following method

  navigate through public zeros & lt; TDestinationViewModel & gt; () Where TDestinationViewModel: ViewModelBase {// I wish to use something like des = _routingDictionary [typeof (TDestinationViewModel)]}  

But it does not work and I get a compile error is

you can not convert from 'System.Type' 'GalaSoft the .MvvmLight.ViewModelBase'

the following are I can solve this by using

  Navigate through public zeros & lt; TDestinationViewModel & gt; () Where TDestinationViewModel: ViewModelBase, New () {TDestinationViewModelDes = New TDestinationViewModel (); Type destination = _routingDictionary [dace]; }  

While there is no better way to do this?

You have declared the other way dictionary that ViewModelBase is an important and Type should be in the form of a value

this should be

  Private IDictionary. & Lt; Type, ViewModelBase & gt; _routingDictionary;  

Who says that type will be an important and will see ViewModelBase as a value.
