Methods
| Name | Description | |
|---|---|---|
|
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[]).) |
|
Equals | Determines whether the specified Object is equal to the current Object. (Inherited from Object.) |
.gif "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.) |
|
GetHashCode | Serves as a hash function for a particular type. (Inherited from Object.) |
|
GetType | Gets the Type of the current instance. (Inherited from Object.) |
|
MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
|
OnSiteChanged | Raises the SiteChanged event. (Inherited from ObjectWithSite.) |
|
ToString | Returns a string that represents the current object. (Inherited from Object.) |
Top
Events
| Name | Description | |
|---|---|---|

SiteChanged | Event that is raised when the Site property is changed. (Inherited from ObjectWithSite.) |

Explicit Interface Implementations
| Name | Description | |
|---|---|---|
.gif "Explicit interface implemetation") .gif "Private 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.) |
|
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.
