所以!我的头刚刚爆炸,因为这对我来说似乎很奇怪。使用调试模式,我可以看到 Claimsresponse 进入方法,它被填充,Email 属性也是如此。但是当我尝试一个简单的字符串 myStr = response.Email; 它抛出一个 NullException 错误......
我不明白。。
代码:(设置电子邮件失败!)
public static bool LoginUserUsingOpenID(BaseDBContext db, ClaimsResponse r)
{
string email = r.Email;
bool doesntExist = !UserHelper.DoesUserExist(db, r.Email);
User u = null;
if (doesntExist)
{
u.Email = email;
u.Username = "User" + new Random().Next(100000);
u.Password = CreateRandomPassword(7);
u.prepareForCreationFromThirdParty();
}
else
{
u = db.Users.Where(x => x.Email == r.Email).FirstOrDefault();
}
SetUserAsAuthenticated(u);
AddAutomaticLoginKeyForUser(db, u); //Need to get this to the users frontend somehow..
return true;
}
这是堆栈跟踪:
System.NullReferenceException: Object reference not set to an instance of an object.
