I can't create a custom ValidationAttribute in asp.net 3.5 webservice. Everything seems ok, it compiles and it runs, it just doesn't enter the custom attribute i created. Msdn documentation (http://msdn.microsoft.com/en-us/library/cc668224(v=vs.90).aspx) states that I have to override the IsValid method to get it validated, still it doesn't enter the IsValid. I guess there's a configuration problem and i can't see any other flaw in the code atm.

So, here's the webservice code

    [WebMethod]
    [Authorize("me")]
    public string test()
    {
        return "Here I am";
    }

and this is the ValidationAttribute

public class AuthorizeAttribute : ValidationAttribute { public string me { get; private set; } public AuthorizeAttribute(string me) { if (string.IsNullOrEmpty(me)) { throw new ArgumentNullException("Not me!"); }

        this.me = me;
    }

    public override bool IsValid(object value)
    {
        bool result = false;
        return result;
    }


}

I would say that before the webmethod executes it goes into the Constructor(at least that!) and then into the IsValid method, but it doesn't.

Can you say where's the error?

Thanks

下面是我项目中的代码，看看它是否对你有帮助，因为它的工作和实施

protected override ValidationResult IsValid(object value,
                                            ValidationContext validationContext)
{
    if (value == null || string.IsNullOrWhiteSpace(value.ToString()))
    {
        var property = validationContext.ObjectInstance.GetType()
            .GetProperty(_fieldName);

        var propertyValue = property.GetValue(validationContext.ObjectInstance, null);


        if (Validate(propertyValue))
        {
            return new ValidationResult(
                string.Format(ErrorMessageString, validationContext.DisplayName));
        }
    }
    return ValidationResult.Success;
}
