    column.ExtendedProperties.Add("TimeStamp", DateTime.Now);
}

private void GetProperty(DataColumn column)
{
    Console.WriteLine(column.ExtendedProperties["TimeStamp"].ToString());
}

 Private Sub SetProperty(column As DataColumn)
     column.ExtendedProperties.Add("TimeStamp", DateTime.Now)
 End Sub    
    
 Private Sub GetProperty(column As DataColumn)
     Console.WriteLine(column.ExtendedProperties("TimeStamp").ToString())
End Sub

Remarks

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.
