Adds multiple key-value pairs to a dictionary. If a key exists in both the current instance and dictionaryToAdd, then the value is updated with the value from keysAndValues> (no exception is thrown). Since IDictionary<TKey,TValue> inherits from IEnumerable<KeyValuePair<TKey,TValue>>, this method can be used to merge one dictionary into another.

public void AddMany(
	IEnumerable<KeyValuePair<TKey, TValue>> keysAndValues
)

Public Sub AddMany ( _
	keysAndValues As IEnumerable(Of KeyValuePair(Of TKey, TValue)) _
)

public:
void AddMany (
	IEnumerable<KeyValuePair<TKey, TValue>>^ keysAndValues
)

AddMany takes time O(M log (N+M)), where M is the size of keysAndValues>, and N is the size of this dictionary.
