部分代码解释：
（1）
private void btnGet_Click(object sender,ImageClickEvevtArgs e)
{
User NewUser=new User();
NewUser.Name = this.txtName.Text.Trim();
NewUser.Mail = this.txtEMail.Text.Trim();
这是一个Password按钮事件函数。以上这段代码新建了一个User类对象，并设置用户名和Email属性信息。
（2） if(NewUser.Check())
{
try
{
string Password = NewUser.GetPassword();
if(Password == "")
{
lblInfo.Text = "Sorry,send password FAILED,plz contact with webmaster.";
}
用户输入自己的用户名后，系统将会根据用户输入的信息，检测该用户是否存在。若该用户不存在，则会显示密码为空，系统会提示错误信息。
（3） else {
MailMessage Mailer = new MailMessage();
Mailer.From = "Webmaster@hugo.com";
Mailer.To = this.txtEMail.Text.Trim(); Mailer.Subject = "Get password--DBProjectGuide BookShop";
Mailer.Body = "Hi,name :" + this.txtName.Text.Trim() + " \n password:" + Password;
……
这部分就是系统将所查询到的注册用户的用户名和密码发到注册用户的邮箱里。这时，用户就可以去邮箱直接取回登录密码。

lblInfo.Text = "Password has been sent to your email.";
lblInfo.ForeColor = Color.Blue;
}
}
catch(Exception ex)
{
lblInfo.Text = "Sorry,send password FAILED!" + ex.Message;
}
}
else
{
lblInfo.Text = "Plz enter your correct name and email.";
}
}
发送成功的话就会在系统就会给出提示信息，提示密码已经发到您的邮箱里；如果因邮箱输入错误而致使发送失败的话，系统也会给出提示，要求用户填写正确的名字的邮箱。
3）修改密码
