The AdoDotNetObjectEnumerator type exposes the following members.

Constructors

  Name Description
Public method AdoDotNetObjectEnumerator Class constructor. Instantiates a new instance of the AdoDotNetObjectEnumerator class.

Properties

  Name Description
Protected property Connection Retrieves the current data connection. (Inherited from DataObjectEnumerator.)
Public property Site Retrieves or sets the object site. (Inherited from ObjectWithSite.)

Top

Methods

  Name Description
Public method EnumerateObjects Enumerates items for a set of data objects of the specified type with the specified restrictions and sort string, if supported. (Overrides DataObjectEnumerator.EnumerateObjects(String, array<Object[], array<Object[], String, array<Object[]).)
Public method Equals Determines whether the specified object is equal to the current object. (Inherited from Object.)
Protected method Finalize Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
Public method GetHashCode Serves as a hash function for a particular type. (Inherited from Object.)
Public method GetType Gets the Type of the current instance. (Inherited from Object.)
Protected method MemberwiseClone Creates a shallow copy of the current Object. (Inherited from Object.)
Protected method OnSiteChanged Raises the SiteChanged event. (Inherited from ObjectWithSite.)
Public method ToString Returns a string that represents the current object. (Inherited from Object.)

Top

Events

  Name Description
Public event SiteChanged Event that is raised when the Site property is changed. (Inherited from ObjectWithSite.)

Top

Explicit Interface Implementations

  Name Description
Explicit interface implemetationPrivate method IObjectWithSite.GetSite Retrieves the last site set using the IObjectWithSite.SetSite method. In cases where there is no known site, the object returns an exception. (Inherited from ObjectWithSite.)
Explicit interface implemetationPrivate method IObjectWithSite.SetSite Provides the site's pointer to the site object. (Inherited from ObjectWithSite.)

Remarks

It is not expected that a data provider based on ADO.NET will need to customize object enumeration. However, this class provides a managed base class that can be extended in case extra or modified enumeration functionality is required inside Visual Studio.

The EnumerateObjects method takes in its parameter array a single string that specifies the name of the ADO.NET schema collection to enumerate.

Thread Safety

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
