I have used the login and register snippets and wish to provide a retrieve password service using a form. but receive the error 'CS1502: The best overloaded method match for 'Umbraco.Core.Services.IMemberService.SavePassword(Umbraco.Core.Models.IMember, string)' has some invalid arguments' for the code below.

@inherits Umbraco.Web.Macros.PartialViewMacroPage @using System.Web.Mvc.Html @using ClientDependency.Core.Mvc @using System.Net.Mail @using System.Text.RegularExpressions; @using System.Web.Security; @using Umbraco.Core; @using Umbraco.Core.Models; @using Umbraco.Core.Services; @using Umbraco.Web.WebApi; @using Umbraco.Web; @using Umbraco.Web.Models; @using Umbraco.Web.Controllers;

@{ var Message=""; if(IsPost) {

    var email = Request["tb_email"];
    var cMember = ApplicationContext.Services.UserService.GetByEmail(email);

    var member = Members.GetByEmail(email);
    var memberid = member.Id;
    var memberName = Membership.GetUser(member.Id).UserName;

   if(member != null)
    {
        @* GENERATE NEW PASSWORD *@
        var  newpassword =  Membership.GeneratePassword(10, 1).ToString();
        newpassword = Regex.Replace(newpassword, @"[^a-zA-Z0-9]", m => "9");

        @* Change the password to the new generated one above *@

        ApplicationContext.Current.Services.MemberService.SavePassword(memberid, newpassword); 

        Message ="<h3 style='color:red;'>Your new password has been sent to "  + email + "</h3>";

        }
            else
        {
