Name

IDictionary

Synopsis

This base interface for a collection of key/value elements defines the indexer (the this property), as well as the Keys and Values properties that return collections containing the dictionary’s keys or values, respectively. This interface also defines the methods by which the entries may be modified, such as Add(), Clear(), and Remove().

public interface IDictionary : ICollection, IEnumerable {
// Public Instance Properties
   public field bool IsFixedSize{get; } 
   public field bool IsReadOnly{get; } 
   public field ICollection Keys{get; } 
   public field object this{set; get; } 
   public field ICollection Values{get; } 
// Public Instance Methods
   public method void Add(object key, object value);  
   public method void Clear();  
   public method bool Contains(object key);  
   public method IDictionaryEnumerator GetEnumerator();  
   public method void Remove(object key);  
}
