Examples

The following example adds a timestamp value to the DataTable through the ExtendedProperties property.


Private Sub GetAndSetExtendedProperties(ByVal myTable As DataTable)
   ' Add an item to the collection.
   myTable.ExtendedProperties.Add("TimeStamp", DateTime.Now)
   ' Print the item.
   Console.WriteLine(myTable.ExtendedProperties.Item("TimeStamp"))
End Sub


private void GetAndSetExtendedProperties(DataTable myTable){
   // Add an item to the collection.
   myTable.ExtendedProperties.Add("TimeStamp", DateTime.Now);
   // Print the item.
   Console.WriteLine(myTable.ExtendedProperties["TimeStamp"]);
}
