PropertyCollection Class
Represents a collection of properties that can be added to DataColumn, DataSet, or DataTable.
Assembly: System.Data (in System.Data.dll)
The PropertyCollection can be accessed through the ExtendedProperties property of the DataColumn, DataSet, or DataTable class.
Add custom properties to the DataColumn, DataSet, or DataTable objects through the PropertyCollection. For example, you may want to store the time of the object's creation for later comparison to another object.
The following example creates a timestamp value for a DataTable and adds it to the PropertyCollection.
Private Sub AddTimeStamp() 'Create a new DataTable. Dim table As New DataTable("NewTable") 'Get its PropertyCollection. Dim properties As PropertyCollection = table.ExtendedProperties 'Add a timestamp value to the PropertyCollection. properties.Add("TimeStamp", DateTime.Now) 'Print the timestamp. Console.WriteLine(properties("TimeStamp")) End Sub
