ResetPassword method in ASP.NET 4.0

The ResetPassword method is able to reset the old password, but user is unable to login with the new password generated by ResetPassword method. Code:

String user =(((TextBox)PasswordRecovery2.Controls[0].FindControl("UserName")).Text).ToString();
String newPassword = clsStatic.RandomString(10, false);
MembershipUser username = Membership.GetUser(user);
String resetPassword = username.ResetPassword();
username.ChangePassword(resetPassword, newPassw开发者_如何学JAVAord);

Does ChangePassword return true or false?

I bet your random function returns a password that doesn't meet the criteria specified in your web.config membership section.

Since ResetPassword already gives you a new valid password why do you have to generate another one?

Your new random password generation should be ideally one of these

// this will automatically take care of all password criteria
string newPassword = Membership.GeneratePassword(10, 0);

Or

//for generating alpha numeric password only
string newPwd = Guid.NewGuid().ToString().Substring(0, 11).Replace("-", "");

Your code is fine otherwise.
