OrderedDictionaryTKey, TValueGetValueElseAdd Method
Finds a key in the dictionary. If the dictionary already contains a key equal to the passed key, then the existing value is returned via value. If the dictionary doesn't contain that key, then value is associated with that key.

Namespace: X3Platform.Collections
Assembly: X3Platform.Support (in X3Platform.Support.dll) Version: 1.0.0.0 (2.0.0.0)
Syntax
Copy
public bool GetValueElseAdd(
	TKey key,
	ref TValue value
)

Parameters

key
Type: TKey
The new key.
value
Type: TValue
The new value to associated with that key, if the key isn't present. If the key was present, returns the exist value associated with that key.

Return Value

Type: Boolean
True if key was already present, false if key wasn't present (and a new value was added).
Remarks

between keys is determined by the comparison instance or delegate used to create the dictionary.

This method takes time O(log N), where N is the number of keys in the dictionary. If a value is added, It is more efficient than calling TryGetValue followed by Add, because the dictionary is not searched twice.
