Hey Everyone,

I have extended the Member in BackOffice to have a Nested Content object on it called badges. Basically a logged in user can do things on the website to unlock/earn badges. I have an UmbracoAPIController handling the call from the front end which looks as shown

    [System.Web.Http.HttpGet]
    public IContent IsNewBadge(int newSteps)
    {
        var contentService = ApplicationContext.Services.ContentService;
        var memberService = ApplicationContext.Current.Services.MemberService;

        // all available badges
        var allBadges = contentService.GetById(1144).Children();
        var secMember = Membership.GetUser();

        if (secMember != null)
        {
            var currentMember = memberService.GetByUsername(secMember.UserName);

            // Get all badges this member currently has - or return a new empty list if null
            var allMemberBadges = currentMember.GetValue<List<IContent>>("badges") ?? new List<IContent>();

            foreach (var badge in allBadges)
            {
                // check if the passed in number meets or exceeds a badge's required number
                if (newSteps >= badge.GetValue<int>("badgeStepsRequired"))
                {
                    // if the badge is not already in the list
                    if (!allMemberBadges.Contains(badge))
                    {
                        allMemberBadges.Add(badge);
                        currentMember.SetValue("badges", new List<IContent>(allMemberBadges));
                        memberService.Save(currentMember);
                        return badge;
                    }
                }
            }
        }
        return null;
    }

My question is specifically around the "SetValue" method. Is this even the correct method that I should be using? It seems to only want (string,string) or (string,filestream).

The error that I get is

"Microsoft.CSharp.RuntimeBinder.RuntimeBinderException: 'The best overloaded method match for 'Umbraco.Core.Models.ContentBase.SetPropertyValue(string, string)' has some invalid arguments'"

"The best overloaded method match for 'Umbraco.Core.Models.ContentBase.SetPropertyValue(string, string)' has some invalid arguments"

How can I update my custom member property via API?

Thanks for any suggestions! -Roger
