DataTable.ExtendedProperties Property

Use the ExtendedProperties to add custom information to a DataTable. Add information with the Add method. Retrieve information with the Item method.

Extended properties must be of type String. Properties that are not of type String are not persisted when the DataTable is written as XML.

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

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"]);
}
