How to Resend confirmation email in Asp.Net C#

Question

User-218090889 posted

I have a method at Page_Load that will check if eMail has been confirmed in the aspNetUsers table, if eMail is not confirmed the method will resend the email for confirmation.
Below is the code to resend the eMail.

string user = eMailFromDatabase;
var manager = Context.GetOwinContext().GetUserManager<ApplicationUserManager>();
string code = manager.GenerateEmailConfirmationToken(user);
string callbackUrl = IdentityHelper.GetUserConfirmationRedirectUrl(code, user, Request);
manager.SendEmail(user, "Confirm your account", "Thank you for registering on Our platform. Please confirm your account by clicking <a href=\"" + callbackUrl + "\">here</a>.");

My issue is the when I tried to run the code it shows error message as below
The method or operation is not implemented.

What is it that is wrong with my code?

The stock below. Is the same I use when user register on my site, it sends confirmation eMail, and it is working very well, but I am tring to figure out how I can use it to re-send confirmation email to user.

var manager = Context.GetOwinContext().GetUserManager<ApplicationUserManager>();
string code = manager.GenerateEmailConfirmationToken(user);
string callbackUrl = IdentityHelper.GetUserConfirmationRedirectUrl(code, user, Request);
manager.SendEmail(user, "Confirm your account", "Thank you for registering on Our platform. Please confirm your account by clicking <a href=\"" + callbackUrl + "\">here</a>.");

Hi Enzyme,

 

If you have already used the codes successfully, I think every method is configured correctly in the project.

Could you please set up a bread point in that code line and check the 'manager' variable to see if it is of a correct type?

  

Another suggestion is to set up OWIN Startup Class Detection for that Startup class.

For example, add below configuration information in web.config file.

<add key="owin:appStartup" value="[Namespace].Startup, [AssemblyName]" />

Reference:

Hope helps.

Best regards,

Sean

I have resolved the issue.

I made the UserId to reflect the Id in my database. and it works.

var manager = Context.GetOwinContext().GetUserManager<ApplicationUserManager>();
string code = manager.GenerateEmailConfirmationToken(Id);
string callbackUrl = IdentityHelper.GetUserConfirmationRedirectUrl(code, Id, Request);
manager.SendEmail(Id, "Confirm your account", "Thank you for registering on Our platform. Please confirm your account by clicking <a href=\"" + callbackUrl + "\">here</a>.");

var manager = Context.GetOwinContext().GetUserManager<ApplicationUserManager>();
string code = manager.GenerateEmailConfirmationToken(user);
string callbackUrl = IdentityHelper.GetUserConfirmationRedirectUrl(code, user, Request);
manager.SendEmail(user, "Confirm your account", "Thank you for registering on Our platform. Please confirm your account by clicking <a href=\"" + callbackUrl + "\">here</a>.");
