How would you get the Sql Command objects for a Given TableAdaptor and SqlDataAdaptor in C# (.NET 2.0)

SqlDataAdapter da = new SqlDataAdapter();
var cmd1 = ((IDbDataAdapter)da).DeleteCommand;
var cmd2 = ((IDbDataAdapter)da).UpdateCommand;
var cmd3 = ((IDbDataAdapter)da).SelectCommand;
var cmd4 = ((IDbDataAdapter)da).InsertCommand;

if (SqlCommandObj.GetType().Name.Contains("TableAdapter"))
 {
     sqlCmdInsert = (SqlCommand)(SqlCommandObj.GetType().GetField("InsertCommand").GetValue(SqlCommandObj));
 }
