Hi, Dictionary: It returns error if we try to find a key which does not exist. It is faster than a Hashtable because there is no boxing and unboxing. Only public static members are thread safe. Dictionary is a generic type which means we can use it with any data type. Hashtable: It returns null if we try to find a key which does not exist. It is slower than dictionary because it requires boxing and unboxing. All the members in a Hashtable are thread safe. Hashtable is not a generic type.
