| Hi, I see that it's possible to apply attributes to function parameters. Wouldn't it be great if the compilers could use these to generate borderplate code, such as parameter checking. Eg instead of typing void MyFunction(string param1, int param2) { if(param1 null) throw new ArgumentNullException("param1"); if(param2 0) throw new ArgumentOutOfBoundsException("param2"); if(param2 99) throw new Arg... |

When I initially wrote our DAL, I built the SqlParameters dynamically because this is how my clients pretty much demand I do it in the past. It worked well exce... |
