如何从asp.net-membership获取用户名和用户it并将其绑定到dropdown listz？

Question

我正在尝试从Membership.GetAllUsers()获取userName和userID，以将其绑定到下拉列表

   private void Bind_usersList()
    {
        var dictionary = Membership.GetAllUsers().Cast<MembershipUser>();
    }

Answer 1

MembershipUser没有"userID“，而是一个ProviderUserKey，它可以是Guid(f.e.在SqlMembershipProvider中)。

这应该是可行的：

MembershipUserCollection members = Membership.GetAllUsers();
DdlUsers.DataSource = members.Cast<MembershipUser>()
    .ToDictionary(m => m.ProviderUserKey, m =>  m.UserName);
DdlUsers.DataValueField = "Key";
DdlUsers.DataTextField = "Value";
DdlUsers.DataBind();
