Question

I have a WPF application from a client that I need to add a IsInRoleAtrribute to for certain methods in a class.

So I created my IsInRole class like this, as a test;

namespace CustomAttributeSample
{
    [System.AttributeUsage(System.AttributeTargets.Method)]
    public class IsInRoleAttribute : Attribute
    {
        public string Role { get; set; }

        public IsInRoleAttribute()
        {
            //open the xml file
            XmlDocument xmlDocument = new XmlDocument();
            xmlDocument.Load("Data.xml");
        }

        public override bool Match(object obj)
        {
            return false;
        }

        public override bool Equals (object obj)
        {
            return false;
        }
    }
}

And I decorate my method like this, again as a test so far;

    [IsInRole(Role="Admin")]
    private bool Save()
    {

However I cannot prevent the method from being executed.

I can do this in MVC no probs but this is my first WPF application in a number of years so I know I’m missing something here.

not very familiar with that either but try to put this instead:

[AuthorizationAttribute(AuthorizationType.Allow, "Admin")]

this should work if you are using the MVVM paradigm 😉
