Flags with web services

Question

I have a flag attribute enumeration that is behind a web service as follows:

[Serializable,Flags]
public enum AccessLevels
{
    None = 0,
    Read = 1,
             


        

Answer 1

I had a similar problem and got round it by adding another web service to return the currect flag values first.

Those then became the values I used in the compare.

Might not be the cleanest solution but it works.

Edit:

My original answer suggested that the values are passed across as a separate web service rather than within an enum.

However, poking around, it appears that an enumeration of 0,1,2 being mapped to 1,2,4 across a web service (even that the [Flags] attribute is set) is a common problem.

The solution suggested by a number of people is to modify the original enumeration definition and start from 1 rather than 0.
