C # What exception should I raise here?

Question

[WebService(Namespace = "http://service.site.com/service/news")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
[ToolboxItem(false)]
[ScriptService]
public class NewsService : System.Web.Services.WebService
{
    [WebMethod]
    [ScriptMethod]
    public void DoPost(string title, string markdown, int categoryId)
    {
        if (!MembershipHelper.IsAtLeast(RoleName.Administrator))
            throw new AuthenticationException();

        // ...
    }
}

There are several options, but none of them are specifically designed for such cases.

i.e:

• UnauthorizedAccessException: I / O
• AccessViolationException: memory stuff
• SecurityAccessDeniedException : Represents a security exception that is thrown when a security authorization request fails.

and etc.

Should I create my own exception type for this? What exception should occur when membership users do not have sufficient privileges to invoke a method?

Answer 1

AccessViolationException - . . ( ), . -, , .

UnauthorizedAccessException . , , .

Answer 2

UnauthorizedAccessException ; -. , .
