C # Development notes for small software (SaveClassic) -- (3) Basic Class (registry operation class RegEdit)

 

This class mainly implements the modification of the Registry, and the code is also in the vernacular, which is very simple and will be used in form development. The Code is as follows.

1 using Microsoft. Win32;

2 namespace Common

3 {

4 public class RegEdit

5 {

6 public RegEdit ()

7 {

8}

9 // obtain data in the Registry

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 // write the registry data www.2cto.com

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 // Delete registry data

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 // determine whether the data in the registry exists

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}
