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;
}

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);
