• bool Add(number key "Add with specific key", AnyType value "Add with specific value") - Adds the specified key and value to the dictionary.
  
• Empty Clear() - Remove all keys and values from the dictionary.
  
• bool ContainsKey(string key "Check with specific key") - Determines whether the dictionary contains the specified key.
  
• bool ContainsKey(number key "Check with specific key") - Determines whether the dictionary contains the specified key.
  
• bool ContainsValue(AnyType value "Add with specific value") - Determines whether the dictionary contains the specified value.
  
• AnyType this[] { get; }(string key "The key used to lookup the value.") - Get an item based on a key.
  
• AnyType this[] { get; }(number key "The key used to lookup the value.") - Get an item based on a key.
  
• AnyType Remove(string key "Check with specific key") - Remove the value with the specified key from the dictionary.
  
• AnyType Remove(number key "Remove with specific key") - Remove the value with the specified key from the dictionary.
  
• Empty this[] { set; }(string key "The key used to lookup the value.", AnyType value "The value to set.") - Set an item based on a key and a value.
  
• Empty this[] { set; }(number key "The key used to lookup the value.", AnyType value "The value to set.") - Set an item based on a key and a value.
  
• string ToString() - The string representation of the object.
  
• AnyType TryGetValue(string key "Remove with specific key") - Gets the value associated with the specified key.
  
• AnyType TryGetValue(number key "Remove with specific key") - Gets the value associated with the specified key.
  

Properties

• number Count { get; } - Gets the number of key/value pairs contained in the dictionary.
  
• array Keys { get; } - Gets a list of keys.
  
• string ObjectTypeName { get; } - The name of the type of object.
  
• array SortedKeys { get; } - Gets a list of keys sorted by current collation.
