注册机的使用

①、新建了一个SoftReg类，用来获取本台电脑的配置
namespace QQ邮件发送
{
    class SoftReg 
    {
        //获取硬盘卷标号
        public string GetDiskVolumeSerialNumber()
        {
            ManagementClass mc = new ManagementClass("win32_NetworkAdapterConfiguration");
            ManagementObject disk = new ManagementObject("win32_logicaldisk.deviceid=\"c:\"");
            disk.Get();
            return disk.GetPropertyValue("VolumeSerialNumber").ToString();
        }

        // 获取CPU序列号
        public string GetCpu()
        {
            string strCpu = null;
            ManagementClass myCpu = new ManagementClass("win32_Processor");
            ManagementObjectCollection myCpuCollection = myCpu.GetInstances();
            foreach (ManagementObject myObject in myCpuCollection)
            {
                strCpu = myObject.Properties["Processorid"].Value.ToString();
            }
            return strCpu;
        }

        // 生成机器码
        public string GetMNum()
        {
            string strNum = GetCpu() + GetDiskVolumeSerialNumber();
            string strMNum = strNum.Substring(0, 24);    //截取前24位作为机器码
            return strMNum;
        }

        public int[] intCode = new int[127];    //存储密钥
        public char[] charCode = new char[25];  //存储ASCII码
        public int[] intNumber = new int[25];   //存储ASCII码值

        //初始化密钥
        public void SetIntCode()
        {
            for (int i = 1; i < intCode.Length; i++)
            {
                intCode[i] = i % 9;
            }
        }

        // 生成注册码
        public string GetRNum()
        {
            SetIntCode();
            string strMNum = GetMNum();
            for (int i = 1; i < charCode.Length; i++)   //存储机器码
            {
                charCode[i] = Convert.ToChar(strMNum.Substring(i - 1, 1));
            }
            for (int j = 1; j < intNumber.Length; j++)  //改变ASCII码值
            {
                intNumber[j] = Convert.ToInt32(charCode[j]) + intCode[Convert.ToInt32(charCode[j])];
            }
            string strAsciiName = "";   //注册码
            for (int k = 1; k < intNumber.Length; k++)  //生成注册码
            {
                if ((intNumber[k] >= 48 && intNumber[k] <= 57) || (intNumber[k] >= 65 && intNumber[k]
                    <= 90) || (intNumber[k] >= 97 && intNumber[k] <= 122))  //判断如果在0-9、A-Z、a-z之间
                {
                    strAsciiName += Convert.ToChar(intNumber[k]).ToString();
                }
                else if (intNumber[k] > 122)  //判断如果大于z
                {
                    strAsciiName += Convert.ToChar(intNumber[k] - 10).ToString();
                }
                else
                {
                    strAsciiName += Convert.ToChar(intNumber[k] - 9).ToString();
                }
            }
            return strAsciiName;
        }

    }
}
二、给软件加上注册码

            this.im = Image.FromFile("1.jpg");
            this.BackgroundImage = im;
        }
        string file;
        //string aa;
        ArrayList Lujing=new ArrayList();
     
        private void button6_Click(object sender, EventArgs e) //添加附件
        {
            openFileDialog1.Filter = "Word文件.doc|*.doc|表格文件.xls|*.xls|所有文件|*.*"; //筛选文件类型
            DialogResult dk = openFileDialog1.ShowDialog();  //创建一个枚举类型的变量dk来接收打开这个对话框
            if (dk == DialogResult.OK) //如果点的是确定,才会执行下面的代码
            {
             
                string[] files = openFileDialog1.FileNames;//将获取到的所有路径都存到一个string类型的数组里面
                foreach (string file in files)//遍历所有路径，一条条的加到Lujing这个ArrayList里面去，然后用的时候再从集合里面一条条遍历出来
                {
                    Lujing.Add(file);
                    txtfujianname.AppendText(file + "\r\n");//AppendText追加文本
                }
                MessageBox.Show("添加附件成功");
                //获取附件的名字添加到文本框当中
            }


        }

                // //设置用于验证发件人身份的凭据
