Displaying the error message in TryUpdateModel in MVC4

Question

My Code :-

 

if (TryUpdateModel(model))

{

//My Logic

}

else

{

ActivityLogger.LogActivity("HandleReceiverAddressSubmitted Method" + ModelState.Values);

}

 

Here in "ModelState.Values" rather then giving the actual error message its showing as 'System.Collections.Generic.Dictionary`2+ValueCollection'

 

Could you please help me how do I Log the error message If any error occurred in the TryUpdateModel in MVC4 in my code.
