Example

[Visual Basic, C#] Note   This example shows how to use one of the overloaded versions of Add. For other examples that might be available, see the individual overload topics.

[Visual Basic] 
Private Sub AddRelation()
    Dim myTable As New DataTable()
    Dim myCol1 As DataColumn = myTable.Columns.Add("Column1")
    Dim myCol2 As DataColumn = myTable.Columns.Add("Column2")
    myTable.ChildRelations.Add("New Relation", myCol1, myCol2)
End Sub

[C#] 
private void AddRelation() {
   DataTable myTable = new DataTable();
   DataColumn myCol1 = myTable.Columns.Add("Column1");
   DataColumn myCol2 = myTable.Columns.Add("Column2");
   myTable.ChildRelations.Add("New Relation", myCol1, myCol2);
}
