How to Verify Username and Password for Login in C# WinForm

When building a login system in a C# WinForm application, it is crucial to verify if the entered username and password are correct. This process involves comparing the user input against the stored credentials to authenticate the user. Here's how you can check if the username and password are correct for login in C# WinForm:

1. Retrieve the entered username and password from the login form.
2. Query the database or any storage medium where user credentials are stored.
3. Compare the entered username and password with the retrieved credentials.
4. If the credentials match, grant access to the user; otherwise, display an error message indicating invalid login details.

By following these steps, you can ensure a secure login process in your C# WinForm application.
