Insert(TKey, TValue)

Inserts a new key-value pair into this cache, or overwrites the value for an existing key.

public abstract void Insert(TKey key, TValue value)

Parameters

Type	Name	Description
TKey	key	The cached value's key.
TValue	value	The value to cache.

TryGet(TKey, out TValue)

Tries to query the cache for the value with a particular key.

Declaration
