Get list of users belonging to a role using Authorization Manager (AzMan)

Question

Using ASP.NET (C#) I have set up Authorization Manager to allow me to handle roles on a website. Added users to roles is simple Roles.AddUserToRole("DOMAIN\\UserName", "role"). However I want to list the users belonging to a role, but since they are stored as SID's, displaying them would not be that helpful. To get the users, I am thinking XML would have to be used, although is it possible to use COM Interop to both do that and get the user name? Either way, how can I get the users belonging to a role?

The table to manage roles would basically be like this:

Role    User
----    ----
admin   DOMAIN\UserName [delete]
        DOMAIN\UserName2 [delete]
        [add user text box]
news    DOMAIN\UserName3 [delete]
        [add user text box]

Found a way of doing it (IAzRole Interface, thanks to Bermo), looping through the MembersName property on each role. No need to map back to a windows account, unless you need to get more than the user name.

Setup roles as detailed in article: How To: Use Authorization Manager (AzMan) with ASP.NET 2.0

In Visual Studio Project add reference to AzMan COM library (azroles 1.0 Type Library). Then add using AZROLESLib;. Add <form id="form1" runat="server">, then in Page_Load:

AzAuthorizationStoreClass AzManStore = new AzAuthorizationStoreClass();
string connString = ConfigurationManager.ConnectionStrings["AuthorizationServices"].ConnectionString;
string path = Server.MapPath(connString.Substring("msxml://".Length));
AzManStore.Initialize(0, "msxml://" + path, null);
IAzApplication azApp = AzManStore.OpenApplication("AppName", null);
PlaceHolder p = new PlaceHolder();
StringBuilder sb = new StringBuilder();
sb.Append("<ul>");
foreach (IAzRole role in azApp.Roles)
{
    sb.Append("<li>");
    sb.Append(role.Name);
    sb.Append("<ul>");
    foreach (object member in (object[])role.MembersName)
    {
        sb.Append("<li>");
        sb.Append(member);
        sb.Append("</li>");
    }
    sb.Append("</ul>");
    sb.Append("</li>");
}
sb.Append("</ul>");
p.Controls.Add(new LiteralControl(sb.ToString()));
form1.Controls.Add(p);

This displays a list of roles and members in each role.
