Hi ,
I need your opinions about whether to use a global return code for each method in my application or let every component throw its exception and use the upper layer to handle it.
Example :
public RetCode ABC ()
{
If(…)
Return RetCode.Valid;
Else
Return RetCode.Invalied;
}
OR
public void ABC ()
{
If(…)
…
Else
Throw new Exception (…);
}
Thanks

You should probably use exceptions because they force the caller to handle it whereas it is easy to forget to check a return code. There is a cost in throwing exceptions but since they are meant to be used in "exceptional circumstances" this should not be an issue.
Consider subclassing the Exception class and add a property to store your error code:
[Serializable()]
public class MyCustomException : Exception {
private RetCode _errorCode;
public MyCustomException( string message, RetCode errorCode ) : base( message ) {
_errorCode = errorCode;
}
//There are some other special constructors you should have, check the documentation for the Exception class.
public property RetCode ErrorCode {
get { return _errorCode; }
}
}
