c#小软件(SaveClassic)开发手记--（3）基础类（注册表操作类RegEdit）

     该类主要实现了注册表的修改，代码也是大白话，很简单，使用方法在窗体开发中也会用到的。具体代码如下所示。

 1 using Microsoft.Win32;
 2 namespace Common
 3 {
 4     public class RegEdit
 5     {
 6         public RegEdit()
 7         {
 8         }
 9 //获取注册表中的数据
10         public string GetRegistData(string name)
11         {
12             string registData;
13             RegistryKey hkml = Registry.LocalMachine;
14             RegistryKey software = hkml.OpenSubKey("SOFTWARE", true);
15             RegistryKey aimdir = software.OpenSubKey("Microsoft", true);
16             registData = aimdir.GetValue(name).ToString();
17             return registData; 
18         }
19 //写入注册表数据
20         public void WTRegedit(string name, string tovalue)
21         {
22             RegistryKey hklm = Registry.LocalMachine;
23             RegistryKey software = hklm.OpenSubKey("SOFTWARE", true);
24             RegistryKey aimdir = software.CreateSubKey("XXX");
25             aimdir.SetValue(name, tovalue);
26         }
27 //删除注册表数据
28         public void DeleteRegist(string name)
29         {
30             string[] aimnames;
31             RegistryKey hkml = Registry.LocalMachine;
32             RegistryKey software = hkml.OpenSubKey("SOFTWARE", true);
33             RegistryKey aimdir = software.OpenSubKey("XXX", true);
34             aimnames = aimdir.GetSubKeyNames();
35             foreach (string aimKey in aimnames)
36             {
37                 if (aimKey == name)
38                     aimdir.DeleteSubKeyTree(name);
39             }
40         }
41 
42 //判断注册表中数据是否存在
43         public bool IsRegeditExit(string name)
44         {
45             bool _exit = false;
46             string[] subkeyNames;
47             RegistryKey hkml = Registry.LocalMachine;
48             RegistryKey software = hkml.OpenSubKey("SOFTWARE", true);
49             RegistryKey aimdir = software.OpenSubKey("Microsoft", true);
50             subkeyNames = aimdir.GetSubKeyNames();
51             foreach (string keyName in subkeyNames)
52             {
53                 if (keyName == name)
54                 {
55                     _exit = true;
56                     return _exit;
57                 }
58             }
59             return _exit;
60         } 
61     }
62 }
