After loading your BusinessEntity you can add custom columns, this is typically done to create a calculated column, however, it can be used to add a column just to hold state, it will not be saved to the database of course.

Parameters

name

The name of the Column

dataType

Use Type.GetType() as in Type.GetType("System.String")

Return Value

The newly created DataColumn

Example

VB.NET

Dim emps As New Employees
If emps.LoadAll() Then

   Dim col As DataColumn = emps.AddColumn("FullName", Type.GetType("System.String"))
   col.Expression = Employees.ColumnNames.LastName + "+ ', ' + " + Employees.ColumnNames.FirstName

   Dim fullName As String

   Do
       fullName = CType(emps.GetColumn("FullName"), String)
   Loop Until Not emps.MoveNext
   

End If

C#

Employees emps = new Employees();
if(emps.LoadAll())
{
    DataColumn col = emps.AddColumn("FullName", Type.GetType("System.String"));
    col.Expression = Employees.ColumnNames.LastName + "+ ', ' + " + Employees.ColumnNames.FirstName;

    string fullName;

    do
        fullName = emps.GetColumn("FullName") as string;
    while(emps.MoveNext());
}
