System.Data (in System.Data.dll)
member ExtendedProperties : PropertyCollection with get
The ExtendedProperties property lets you store custom information with the object. For example, you may store a time when the data should be refreshed.
Extended properties must be of type String. Properties that are not of type String are not persisted when the DataColumn is written as XML.
The following example adds a custom property to the PropertyCollection returned by the ExtendedProperties property. The second example retrieves the custom property.
