MedicalViewerCollection<T> Class

Summary

Represents a generic collection of objects.

Syntax
C#
VB
C++
[SerializableAttribute()] 
[DefaultMemberAttribute("Item")] 
public class MedicalViewerCollection<T> : IList<T>, ICollection<T>, IEnumerable<T>, IEnumerable 
<SerializableAttribute(),  
 DefaultMemberAttribute("Item")>  
Public Class MedicalViewerCollection(Of T) 
   Inherits IList(Of T) 
   Implements ICollection(Of T), IEnumerable(Of T), IEnumerable 
public: 
   [SerializableAttribute,  
   DefaultMemberAttribute(L"Item")] 
   generic<typename T> 
   ref class MedicalViewerCollection : IList<T>, ICollection<T>,  
    IEnumerable<T>, IEnumerable 

Remarks
The MedicalViewerCollection<T> class provides a generic collection class that implements the .NET IList<T>, ICollection<T> and IEnumerable<T> interfaces.

The class contains the ItemAdded and ItemRemoved events. These events will fire whenever objects are added or removed to/from the collection.
