Throw an exception when there's an error. Returning an error code is very C/C++ like and is discouraged in .Net.


>Hi,

>I'm trying to adjust a method so I can get two bits of information out of it. Previously I was just returning an error code, now I would like to return an error message along with the code. I found one way to do this is to use out parameters, so I adjusted my methods definition to this:
>
>

public void SendEmails(Guid emailPK, string subject, string html, out int errorCode, out string errorMessage)

>
>When I try calling this method like this:
>
>

int errorCode;
>string errorMessage;
>emailNotifications.SendEmails(emailPK, email.blk_subject, email.blk_html, out errorCode, out errorMessage);

>
>I get this error:
>
>"No overload for method 'SendEmails' takes 5 arguments"

>Maybe it's too early in th emorning for me but I think I'm counting correctly.

>Can anybody help enlighten me, please?
