GetOrAdd<TKey, TValue>(IDictionary<TKey, TValue>, TKey, TValue)

Adds a key/value pair to the IDictionary<TKey,TValue> if the key does not already exist. Returns the new value, or the existing value if the key already exists.

Declaration

public static TValue GetOrAdd<TKey, TValue>(this IDictionary<TKey, TValue> dict, TKey key, TValue value)

Parameters

Type	Name	Description
IDictionary<TKey, TValue>	dict	The dictionary to be operated on.
TKey	key	The key of the element to add.
TValue	value	The value to be added, if the key does not already exist.

Returns

Type	Description
TValue	The value for the key. This will be either the existing value for the key if the key is already in the dictionary, or the new value if the key was not in the dictionary.

GetValueOrDefault<TKey, TValue>(IDictionary<TKey, TValue>, TKey)

Gets the value that is associated with the specific key or the default value for the type TValue.

Declaration

public static TValue GetValueOrDefault<TKey, TValue>(this IDictionary<TKey, TValue> dict, TKey key)

Parameters

Type	Name	Description
IDictionary<TKey, TValue>	dict
TKey	key

Returns

Type	Description
TValue

Type Parameters

Name	Description
TKey
TValue

Remarks

This is duplicated from GetValueOrDefault<TKey,TValue>(IReadOnlyDictionary<TKey,TValue>, TKey) because IDictionary<TKey,TValue> does not extend IReadOnlyDictionary<TKey,TValue>.
