Question

我创建了一个自定义成员资格提供程序，并且在尝试创建新的“MembershipUser”时出现以下错误。

无法从程序集'System.Web，Version = 4.0.0.0，Culture = neutral，PublicKeyToken = b03f5f7f11d50a3a'加载类型'MyTestApp.Membership.TestMembershipProvider'。

我是从一个单元测试项目运行的，所以我不确定是否会导致这个问题，但我确实包含了System.Web，System.Web.ApplicationServices以及对MyApp.Membership和MyApp的引用。 DataModels（实体对象）。

错误发生在我的“GetUser”函数中，如下所示，我的配置也在下面。

public override MembershipUser GetUser(object providerUserKey, bool userIsOnline)
{
    try
    {
        AccountEntities db = new AccountEntities();

        if ((providerUserKey is Guid) == false)
        {
            return null;
        }

        User user = (from u in db.Users
                     where u.UserId == (Guid)providerUserKey
                     && u.Application.LoweredApplicationName == this.ApplicationName.ToLower()
                     select u).FirstOrDefault();

        if (user != null)
        {   // ERROR: Starts here, user object is correct, data is all there.
            return new MembershipUser(this.ProviderName, user.UserName, (object)user.UserId, user.Email, user.PasswordQuestion, user.Comment, user.IsApproved, user.IsLockedOut, user.CreateDate, user.LastLoginDate, user.LastActivityDate, user.LastPasswordChangedDate, user.LastLockoutDate);
        }
        else
            return null;
    }
    catch (Exception ex)
    {
        this.WriteToEventLog(ex, "Unable to get user from object '{" + ((Guid)providerUserKey).ToString() + "}'.", "Get User");
        return null;
    }
}
