What is the best way to obtain the complete list of permission of a given user using AMO in C#

Finally I am able to achieve this using AMO. Here is what I did to solve this. Following is the code snipped to find out the list of permissions one user has in a given SSAS database. This result is then loaded into a hypothetical DataTable. I hope this will help others trying to find out a similar solution.

using (Server Srv = new Server())
{   
    Srv.Connect("\\serverName\instanceName");                       
    Database d = Srv.Databases.FindByName("My SSAS DB");    
    foreach (Role r in d.Roles)
    {
        foreach (RoleMember m in r.Members)
        {
            if (string.Compare(m.Name, "domainName\userName", StringComparison.InvariantCultureIgnoreCase) == 0)
            {               
                foreach (Cube c in d.Cubes)
                {                                        
                    CubePermission cp = c.CubePermissions.FindByRole(r.ID);
                    if(!(cp == null))
                    {   
                        foreach(CubeDimensionPermission cdimPerm in cp.DimensionPermissions)
                        {
                            foreach(AttributePermission attPerm in cdimPerm.AttributePermissions)
                            {                               
                                DataRow dr = dt.NewRow();
                                dr["Database Name"] = d.Name;
                                dr["Role Name"] = r.Name;
                                dr["Dimension Name"] = cdimPerm.CubeDimension.Name;
                                dr["Cube Name"] = c.Name;
                                dr["Attribute Name"] = attPerm.Attribute.Name;
                                dr["AllowedSet"] = attPerm.AllowedSet;
                                dr["DeniedSet"] = attPerm.DeniedSet;
                                dr["DefaultMember"] = attPerm.DefaultMember;
                                dr["VisualTotals"] = attPerm.VisualTotals;
                                dt.Rows.Add(dr);
                            }
                        }                                            
                    }
                }                                    
            }
        }
    }                   
    Srv.Disconnect();
