what is the difference between the using of viewData dictionary and viewData.Model in asp.net mvc -

i need help.

please explain me difference between using of viewdata dictionary , viewdata.model in asp.net mvc.

for example can write

viewdata["list"] = list; 

and can write

viewdata.model = list; 

so difference between them , when use each one;

explanation example appreciated.

viewdata.model way pass model object controller's action view. can use method ensure view's model strongly-typed, , can reference object using "@model" within view.

@model.someproperty 

alternatively (and preferably), pass model object action view using "return view(t);" t = object.

return view(myobject); 

lastly, using

viewdata.["somename"] = someobject 

would loosely-typed object, , couldn't reference object using @model view. instead, you'd have cast viewdata model-type within view able reference it. example:

// in action: viewdata["obj"] = someobject;  // in view: var objdata = viewdata["obj"] myobjectclass  // referencing property of object: @objdata.someproperty 

so can see there's bit work involved when choose method. personally, don't use viewdata often... viewbag makes more sense me when need send view isn't included part of viewmodel.
