Parameters

key  String

The key whose value to get.

value  TValue

When this method returns, the value associated with the specified key, if the key is found; otherwise, the default value for the type of the value parameter. This parameter is passed uninitialized.

Return Value

Implements

If the key is not found, then the value parameter gets the appropriate default value for the type TValue; for example, 0 (zero) for integer types, for Boolean types, and for reference types.

This method approaches an O(1) operation.
