.net c# winform写注册表实现记住用户名和密码

winform项目中,经常需要记住用户名和密码,可以将用户名和密码写入注册表或者文件的形式实现.

这里展示一下写入注册表的功能,

1.写入注册表

        private void zbtnsave_Click(object sender, EventArgs e)
        {
            try
            {
                string strPath = "HKEY_CURRENT_CONFIG\\UFWin";//设默认值 
                object username = (object)this.zusername.Text.Trim();
                object userpwd = (object)this.zpwd.Text.Trim();
                Registry.SetValue(strPath, "用户名", username, RegistryValueKind.String);
                Registry.SetValue(strPath, "密码", userpwd, RegistryValueKind.String);
                MessageBox.Show("成功写入注删表");
            }
            catch { return; }
        }

2.从注册表中读取

        public void load()
        {
            try
            {
                RegistryKey rk = Registry.CurrentConfig.OpenSubKey("UFWin");
                if (rk == null) { return; }
                if (rk.GetValue("用户名", "Null") != null)
                {
                    zusername.Text = rk.GetValue("用户名", "Null").ToString();
                }
                if (rk.GetValue("用户名", "Null") != null)
                {
                    zpwd.Text = rk.GetValue("密码", "Null").ToString();
                }
            }
            catch { return; }
        }
