调用密码重置电子邮件通知的方法
本文关键字：通知 方法 电子邮件 密码 调用 | 更新日期: 2023-09-27 18:32:27
我想为用户提供一种密码重置方法。当用户选择"发送密码重置"时，将向他们发送电子邮件通知。
现在我从一个存储库工作，我希望调用存在的方法，但不知道我将如何做到这一点，因为我对 c# 很陌生？。
用户存储库中的方法为
public bool RequestPasswordReset(string emailAddress)
{
try
{
User user = this.GetUserByEmailAddress(emailAddress);
// Check we have a user
if (user == null)
throw new Exception("No User for Email");
// Check the user is in a valid state for operation
if (user.Status != (int)UserStatus.Active)
throw new Exception("User not in valid state for password reset");
// TODO: Check UpdateDate to see if the Password Reset Guid has expired!
// Make the user reset, set the passwordguid and clear previous password hash
user.Status = (int)UserStatus.Reset;
user.PasswordHash = "";
user.PasswordGuid = GetUniquePasswordGuid();
//UserDAL.Update(User);
Context.Save(user);
Company company = user.Company;
// Send the appropriate Email Notification
//this.NotificationService.SendPasswordResetNotification(ContentType.Email, User, Company, DateTime.Now);
using (NotificationMessageRepository nmr = new NotificationMessageRepository())
{
nmr.SendPasswordResetNotification(company, user, ContentType.Email, DateTime.Now);
}
//Todo: Audit the password reset
//AuditLogInfo(null, AuditType.Auth, AuditMessage.AuthResetPassword, AuditItemType.User, User.ID.ToString(), Email);
}
catch (Exception e)
{
Logger.Error(String.Format("RequestPasswordReset({0}) Exception: {1}", emailAddress, e.Message));
return false;
}
finally
{
}
return true;
}

public bool SetPassword(string PasswordGuid, string Password)
{
try
{
User user = this.GetUserByPasswordGuid(PasswordGuid);
// Check we have a user
if (user == null)
throw new Exception("No User for PasswordGuid");
// Check the user is in a valid state for operation
if (user.Status != (int)UserStatus.Pending && user.Status != (int)UserStatus.Reset)
throw new Exception("User not in valid state for set password");
// TODO: Check UpdateDate to see if the Password Reset Guid has expired!
// Make the user active, set the password hash from the password and clear the password guid.
user.Status = (int)UserStatus.Active;
user.PasswordHash = CreatePasswordHash(Password);
user.PasswordGuid = "";
//UserDAL.Update(User);
Context.Save(user);
//ToDo: audit the password change
//AuditLogInfo(null, AuditType.Auth, AuditMessage.AuthSetPassword, AuditItemType.User, User.ID.ToString(), User.Username);

return false;
}

{

return true;
}

}
public bool UpdateUser(long userId, string title, string firstName, string surname, string address, string email, string username )
{
bool returnValue = false;
var user = Context.Users.SingleOrDefault(x => x.ID == userId);
if (user.ID > 0)
{
user.Title = title;
user.Forename = firstName;
user.Email = email;
user.Surname = surname;
user.Username = username;
user.Address1 = address;
Context.Save(user);
returnValue = true;
}
return returnValue;

public bool SaveNewUser(User user)

bool returnValue = false;
Context.Users.Add(user);
Context.Save(user);
return returnValue;

只要仓库可以看到RequestPassWordReset方法，就可以通过以下方式调用该方法：
var successfullyReset = YourClassInstance.RequestPasswordReset("emailaddress@domain.com");
通过文本框（来自您的评论）：
string usersEmail = txtEmailAddress.Text;
var successfullyReset = YourClassInstance.RequestPasswordReset(usersEmail);
