Parameters

key  String

The key of the element to add.

value  TValue

The value of the element to add. The value can be for reference types.

Return Value

Unlike the Add method, this method doesn't throw an exception if the element with the given key exists in the StringKeyedDictionaryTValue. Unlike the indexer, TryAdd doesn't override the element if the element with the given key exists in the dictionary. If the key already exists, TryAdd does nothing and returns .
