开发C#软件过程中，要用到注册机制，在网上看到韩兆新老师的一篇文章很有启发，转载分享
（一）软件的实现
SoftReg类：
1: using System;
2: using System.Collections.Generic;
3: using System.Linq;
4: using System.Text;
5: using System.Management; //需要引用System.Management.dll
6:
7: namespace SoftRegister
8: {
9: class SoftReg
10: {

14: ///<returns></returns>
15: public string GetDiskVolumeSerialNumber()
16: {
17: ManagementClass mc = new ManagementClass("win32_NetworkAdapterConfiguration");
18: ManagementObject disk = new ManagementObject("win32_logicaldisk.deviceid=\"c:\"");
19: disk.Get();
20: return disk.GetPropertyValue("VolumeSerialNumber").ToString();
21: }
22:
23: ///<summary>
24: /// 获取CPU序列号
25: ///</summary>
26: ///<returns></returns>

74: }
75: for (int j = 1; j < intNumber.Length; j++) //改变ASCII码值
76: {
77: intNumber[j] = Convert.ToInt32(charCode[j]) + intCode[Convert.ToInt32(charCode[j])];
78: }
79: string strAsciiName = ""; //注册码
80: for (int k = 1; k < intNumber.Length; k++) //生成注册码
81: {

84: <= 90) || (intNumber[k] >= 97 && intNumber[k] <= 122)) //判断如果在0-9、A-Z、a-z之间
85: {
86: strAsciiName += Convert.ToChar(intNumber[k]).ToString();
87: }
88: else if (intNumber[k] > 122) //判断如果大于z
89: {
90: strAsciiName += Convert.ToChar(intNumber[k] - 10).ToString();
91: }
92: else

95: }
96: }
