DataTableMappingCollection mappings =
new DataTableMappingCollection();
mappings.Add("Categories","DataCategories");
mappings.Add("Orders","DataOrders");
mappings.Add("Products","DataProducts");
string message = "TableMappings:\n";
for(int i=0;i < mappings.Count;i++)
{
message += i.ToString() + " "
+ mappings[i].ToString() + "\n";
}
Console.WriteLine(message);
}
Public Sub CreateTableMappings()
Dim mappings As New DataTableMappingCollection()
mappings.Add("Categories", "DataCategories")
mappings.Add("Orders", "DataOrders")
mappings.Add("Products", "DataProducts")
Dim message As String = "TableMappings:" & ControlChars.Cr
Dim i As Integer
For i = 0 To mappings.Count - 1
message &= i.ToString() & " " + mappings(i).ToString() _
& ControlChars.Cr
Next i
Console.WriteLine(message)
