'Usage
Dim instance As SPContentDatabase

    IDatabaseSnapshotRestore, IMigratable

Remarks

Use the ContentDatabase() property of the SPSite class or of the SPWorkItemCollection class to return the content database for a site collection or work item collection. Use the ContentDatabases property of the SPWebApplication class to return the collection of content databases that are used by the Web application.

Use an indexer to return a single content database from a collection of content databases. For example, if the collection is assigned to a variable named myContentDatabases, use myContentDatabases[index] in C#, or myContentDatabases(index) in Visual Basic, where index is either the index number of the field in the collection or the GUID for the content database.

Examples

The following example uses the GetChanges method to report when users have been deleted from the current site collection as represented by the current change log.

Dim siteCollection As SPSite = SPContext.Current.Site

Dim contentDB As SPContentDatabase = siteCollection.ContentDatabase

Dim myQuery As New SPChangeQuery(False, False)
myQuery.User = True
myQuery.Delete = True

Dim changes As SPChangeCollection = contentDB.GetChanges(myQuery)

Dim change As SPChange
For Each change In  changes
    Response.Write((" User deleted: " + change.Time.ToString() + "<BR>"))
Next change
SPSite siteCollection = SPContext.Current.Site;

SPContentDatabase contentDB = siteCollection.ContentDatabase;

SPChangeQuery myQuery = new SPChangeQuery(false, false);
myQuery.User = true;
myQuery.Delete = true;

SPChangeCollection changes = contentDB.GetChanges(myQuery);

foreach (SPChange change in changes)
{
    Response.Write(" User deleted: " + change.Time.ToString() + "<BR>");
}
