DataSet.ExtendedProperties Property

.NET Framework 4.5

Gets the collection of customized user information associated with the DataSet.

Namespace: System.Data

'Declaration
<BrowsableAttribute(False)> _
Public ReadOnly Property ExtendedProperties As PropertyCollection

Property Value

Type: System.Data.PropertyCollection
A PropertyCollection with all custom user information.

Remarks

The ExtendedProperties property enables you to store custom information with the DataSet. For example, you might store a time when the data should be refreshed.

Extended properties must be of type String if you want them persisted when the DataSet is written as XML.

Examples

The following example adds a custom property to the PropertyCollection returned by the ExtendedProperties property. The second example retrieves the custom property.

Private Sub SetProperty(column As DataColumn)
     column.ExtendedProperties.Add("TimeStamp", DateTime.Now)
 End Sub     

 Private Sub GetProperty(column As DataColumn)
     Console.WriteLine(column.ExtendedProperties("TimeStamp").ToString())
End Sub
