POFlags with web services
text
Body
copied!<p>I have a flag attribute enumeration that is behind a web service as follows:</p> <pre><code>[Serializable,Flags] public enum AccessLevels { None = 0, Read = 1, Write = 2, Full = Read | Write } </code></pre> <p>My problem is the consumer of my web service does not have the original constant values of the enum. The resulting proxy class client side has something that amounts to this:</p> <pre><code>{ None = 1, Read = 2, Write = 4, Full = 8 } </code></pre> <p>And thus when the consumer is checking for "Read" access this will be false even when "testItem" is "Full"</p> <pre><code>((testItem & Svc.Read) == Svc.Read) </code></pre> <p>How can I properly provide flags over a web service?</p> <p>EDIT:</p> <p>According to <a href="http://ikriv.com:8765/en/prog/info/dotnet/WebServices_and_Enums.html" rel="nofollow noreferrer">this</a> article it may not be possible to do what I am looking to do. Ivan Krivyakov states</p> <blockquote> <p>Imperfect Transparency of Enums</p> <p>It turns out that enums are not as transparent as we'd like them to be. There are three sticky issues:</p> <ol> <li>If server-side code declares an enum and assigns specific numeric values to its members, these values will not be visible to the client.</li> <li>If server-side code declares a [Flags] enum with "compound" mask values (as in White = Red|Green|Blue), it is not properly reflected on the client side.</li> <li>If server or client transmits an "illegal" value which is outside of the scope of the enum, it causes an exception in XML de-serializer on the other side.</li> </ol> </blockquote> <p>So I wonder if this is just a limitation and is not possible.</p>
