/// <summary>
/// 修改密码保存
/// </summary>
private void Submit()
{
MD5 d = new MD5();
string jM = d.md5(txtNewPasswordQR.Password, 32);
string jieM = d.md5(txtOldPassword.Password, 32);
if (!String.IsNullOrEmpty(txtYHM.Text) && !String.IsNullOrEmpty(txtOldPassword.Password) && !String.IsNullOrEmpty(txtNewPassword.Password) && !String.IsNullOrEmpty(txtNewPasswordQR.Password))
{
if (txtNewPassword.Password.Length >= 6)
{
if (Regex.IsMatch(txtNewPassword.Password, @"^[A-Za-z0-9]{6,16}$"))
{
var olds = (from tbUser in myModels.PW_User where tbUser.UserNuber == strUserNumber select tbUser).Single();
if (olds.Password == jieM)
{
if (txtNewPassword.Password.Trim() == txtNewPasswordQR.Password.Trim())
{
olds.UserName = txtYHM.Text.Trim();
olds.Password = jM;
myModels.Entry(olds).State = System.Data.Entity.EntityState.Modified;
myModels.SaveChanges();
MessageBox.Show("密码修改成功！", "🌎", MessageBoxButton.OK, MessageBoxImage.None);
cP("密码修改成功") ;
WD_LoginWindow lW = new WD_LoginWindow();
this.Close();
lW.Show();
//add(txtZH.Text.Trim());
}
else
{
MessageBox.Show("密码填写不对应！", "🌎", MessageBoxButton.OK, MessageBoxImage.Stop);
}
}

{
MessageBox.Show("旧密码不正确，请重新输入！", "✍", MessageBoxButton.OK, MessageBoxImage.Question);
}
}
