sir can you show me any Example 

To add a password forgot functionality in an MVC C# application, you can follow these general steps:

1. Create a Forgot Password View: Design a view where users can enter their email address to receive instructions on resetting their password.

2. Controller Logic: Implement controller logic to handle the submission of the email address from the Forgot Password View.

3. Verify Email: Check if the entered email address exists in your database. If it does, generate a unique token for resetting the password and store it in the database along with an expiration time.

4. Send Reset Email: Send an email to the user's email address with a link containing the unique token generated in the previous step.

5. Reset Password View: Create a view where users can reset their password by entering a new one.

6. Controller Logic for Reset Password: Implement controller logic to handle the submission of the new password along with the token.

7. Verify Token: Check if the token provided by the user matches the one stored in the database and if it hasn't expired.

8. Update Password: If the token is valid, update the password for the user in the database with the new password provided by the user.
