例外:“值不在预期范围内”.在ASP..NET MVC控制器

我要格式化这个字符串，在这部分(字符串主体....)抛出异常

    private Task SendEmailConfirmation(UserModel user)
    {
        var emailService = new EmailUnsecServiceAgent(null);
    string body = string.Format("Dear {0} <BR/>Thank you for your registration, " +
                                "please click on the below link to complete your" +
                                " registration: <a href='"{1}'" title='"User Email Confirm'">{1}</a>",
                                user.UserName,
                                Url.Action("ConfirmEmail",
                                "Account",
                                new
                                      {
                                          confirmationToken = user.ConfirmationToken,
                                          email = user.Email
                                      },,
                                Request.Url.Scheme));
   return Task.Run(() => emailService.SendEmail("Confirm your account", body, null, true, null, null, null));
}

confirmationToken和email是字符串，我的ConfirmEmail是

[AllowAnonymous]
public async Task<ActionResult> ConfirmEmail(string confirmationToken, string email)
{
    var securityService = new SecurityUnsecServiceAgent(null);
    UserModel user = securityService.GetUserByConfirmationToken(confirmationToken);
    if (user != null)
    {
        if (user.Email == email)
        {
            user.ConfirmedEmail = true;
            securityService.UpdateUser(user);
            return View("RegisterMessage");
        }
        return View("ConfirmEmail", user);
    }
    return RedirectToAction("ConfirmEmail", user);
}

这是StackTrace:

例外:“值不在预期范围内”.在ASP..NET MVC控制器

URL帮助器可能在请求已经被销毁(因为它是异步的)之后尝试创建一个URL。在这种情况下，当您尝试Url.Action()时将得到一个错误。

尝试在非异步控制器中生成电子邮件的正文，并将其作为参数发送到email类中。

问题自定义任务运行器方法抛出ArgumentException似乎与您所看到的密切相关(向下到堆栈跟踪和OP到达答案的方法)。
