.NET Development Foundation/Other system classes

System types and collections: Other system classes Using specialized collections Exam objective: Manage data in a .NET Framework application by using specialized collections. (Refer System.Collections.Specialized namespace) Specialized String classes StringCollection class - MSDN StringDictionary class - MSDN StringEnumerator class - MSDN Specialized Dictionary classes HybridDictionary class - MSDN IOrderedDictionary interface and OrderedDictionary class IOrderedDictionary Interface - MSDN OrderedDictionary class - MSDN ListDictionary class - MSDN Named collections NameObjectCollectionBase class - MSDN NameObjectCollectionBase.KeysCollection class - MSDN NameValueCollection class - MSDN CollectionsUtil class CollectionsUtil class - MSDN BitVector32 structure and BitVector32.Section structure BitVector32 structure - MSDN BitVector32.Section structure - MSDN Standard interfaces Exam objective: Implement .NET Framework interfaces to cause components to comply with standard contracts. (Refer System namespace) IComparable interface - MSDN The IComparable interface defines a comparison method that a value type or class implements to create a type-specific comparison method IDisposable interface - MSDN The IDispose interface can be used to explicitly release unmanaged resources in custom classes. The consumer of an object can call this method when the object is no longer needed. The .Net garbage collector releases memory allocated to managed objects when they are no longer used, however, it is not possible to predict when garbage collection will occur and it has no knowledge of unmanaged resources such as window handles, or open files and streams. IConvertible interface - MSDN ICloneable interface - MSDN INullableValue interface - MSDN IEquatable interface - MSDN IFormattable interface - MSDN
