我创建了一个自定义的会员资格提供程序,在尝试创建一个新的“MembershipUser”时遇到以下错误:
无法从程序集'System.Web,Version=4.0.0.0,Culture=neutral,PublicKeyToken=b03f5f7f11d50a3a'中加载类型'MyTestApp.Membership.TestMembershipProvider'。
我是从一个单元测试项目中运行的,所以我不确定是否引起了这个问题,但我确实包括了System.Web、System.Web.ApplicationServices以及对MyApp.Membership和MyApp.DataModels(实体对象)的引用。
错误发生在我的“GetUser”函数内部,该函数如下,我的配置也如下。
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;
}
}
