c#注册表操作大全 c#注册表的删除、添加、修改、遍历

1.打开键
//using Microsoft.Win32;
RegistryKey rkLocalM = Registry.LocalMachine; //Registry.ClassesRoot, Registry.LocalMachine, Registry.Users, Registry.CurrentConfig
const string strSubKey = %%1; //@"SOFTWARE\ODBC\ODBC.INI\DBNewTest\Test"
RegistryKey rkSub = rkLocalM.OpenSubKey( strSubKey );
//rkLocalM = Registry.LocalMachine; //Registry.ClassesRoot, Registry.LocalMachine, Registry.Users, Registry.CurrentConfig
//rkLocalM.OpenSubKey(%%1);

2.添加键
//using Microsoft.Win32;
RegistryKey rkLocalM = Registry.LocalMachine; //Registry.ClassesRoot, Registry.LocalMachine, Registry.Users, Registry.CurrentConfig
const string strSubKey = %%1; //@"SOFTWARE\ODBC\ODBC.INI\DBNewTest\Test"
RegistryKey rkSub = rkLocalM.CreateSubKey( strSubKey );
rkLocalM.Close();

3.删除键
rkSub.DeleteSubKey( %%1, false );

4.枚举第一个键
//using System.Collections;
IEnumerator<string> it = SubKey.GetSubKeyNames().First();
string %%1=it.Current;

5.枚举下一个键
string %%1=null;
if(it.MoveNext());
%%1=it.Current;

6.获取DWORD值
%%2=rkSub.GetValue(%%1);

7.获取二进制值
%%2=rkSub.GetValue(%%1);

8.读取字符串值
%%2=rkSub.GetValue(%%1);

9.写入字符串值
rkSub.SetValue( %%1, "Test" );

10.写入二进制值
rkSub.SetValue(%%1, value, RegistryValueKind.Binary);

11.写入DWORD值
rkSub.SetValue(%%1, value, RegistryValueKind.DWord);

12.设置DWORD值
rkSub.Add(%%1, value, RegistryValueKind.DWord); 

13.删除值
rkSub.DeleteValue( %%1, false );//"DriverID"

14.关闭键
rkSub.Close();

15.列出一个键下所有的子键
string[] strSubKeys = rkSub.GetSubKeyNames();
for( int i = 0; i < strSubKeys.Length; i++ )
{
string %%1= strSubKeys[i] ;
