How to use ASP.NET Membership class to validate users in C#

The Membership class provides a method for validating a membership user. If a user has entered his user name and password in a login mask, you can use the ValidateUser() method for programmatically validating the information entered by the user, as follows:

 

protected void LoginAction_Click(object sender, EventArgs e)

{

if (Membership.ValidateUser(UsernameText.Text, PasswordText.Text))

{

FormsAuthentication.RedirectFromLoginPage(UsernameText.Text, false);

}

else

{

LegendStatus.Text = “Invalid user name or password!”;

}

}
