.NET Forum / .NET Framework / New Users / July 2006Custom error message
Hi all! I have a singleton-class with private constructor and Instance property. It's clear that access to this class should be got by using this property. "new Class()" construction is incorrect and throws an error "can't access due to its protection level". Is there any opportunity to define custom error when accessing this class constructor? E.g. "This class is singleton. Use should use Instance property to get its instance" Thank you in advance. A. Dzizenko. > I have a singleton-class with private constructor and Instance property. > It's clear that access to this class should be got by using this property. > "new Class()" construction is incorrect and throws an error "can't access > due to its protection level". It doesn't throw an error - it's a compiler error, so there's no user code running. > Is there any opportunity to define custom error when accessing this class > constructor? E.g. "This class is singleton. Use should use Instance > property to get its instance" The best you could do is turn it into a runtime error by making the constructor public. I don't think that would be an improvement, though. -- Barry  Signaturehttp://barrkel.blogspot.com/ I've spoken incorrectly. It's a compiler error. I want to redefine a compiler error. Making constructor public is bad idea. We can't access to the constructor directly because of a sigleton. >> I have a singleton-class with private constructor and Instance property. >> It's clear that access to this class should be got by using this [quoted text clipped - 15 lines] > > -- Barry > I've spoken incorrectly.

I understood you perfectly. You can't create a new compiler error apart from preprocessor errors like: #error "Your error message" but that only works if you want to detect #define conflicts. -- Barry Signaturehttp://barrkel.blogspot.com/
