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

public PropertyCollection ExtendedProperties { get; }
/** @property */
public PropertyCollection get_ExtendedProperties ()

public function get ExtendedProperties () : PropertyCollection

Not applicable.

Property Value

A PropertyCollection with all custom user information.

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.

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

private void SetProperty(DataColumn column)
{
    column.ExtendedProperties.Add("TimeStamp", DateTime.Now);
}
 
private void GetProperty(DataColumn column)
{
    Console.WriteLine(column.ExtendedProperties["TimeStamp"].ToString());
}
