Difference between casting by as and normal cast

[Guest]

I wondering what is the difference between the following two casts

DictionaryEntry entry = obj as DictionaryEntry;
AND

DictionaryEntry entry = (DictionaryEntry)obj;

Hello !

The first one will return null if the types are not compatible instead of raising an exception for the second case.

[Brock Allen]

DictionaryEntry entry = obj as DictionaryEntry;

returns null if cast fails

DictionaryEntry entry = (DictionaryEntry)obj;

throws invalidcastexception when cast fails
