C#操作注册表--DarrenF

步骤/方法

1. 读取指定名称的注册表的值 
   private string GetRegistData(string name) 
   { 
   string registData; 
   RegistryKey hkml = Registry.LocalMachine; 
   RegistryKey software = hkml.OpenSubKey("SOFTWARE",true); 
   RegistryKey aimdir = software.OpenSubKey("XXX",true); 
   registData = aimdir.GetValue(name).ToString(); 
   return registData; 
   } 
   以上是读取的注册表中HKEY_LOCAL_MACHINE\SOFTWARE目录下的XXX目录中名称为name的注册表值；
    
2. 向注册表中写数据 
   private void WTRegedit(string name,string tovalue) 
   { 
   RegistryKey hklm = Registry.LocalMachine; 
   RegistryKey software = hklm.OpenSubKey("SOFTWARE",true); 
   RegistryKey aimdir = software.CreateSubKey("XXX"); 
   aimdir.SetValue(name,tovalue); 
   } 
   以上是在注册表中HKEY_LOCAL_MACHINE\SOFTWARE目录下新建XXX目录并在此目录下创建名称为name值为tovalue的注册表项；
    
3. 删除注册表中指定的注册表项 
   private void DeleteRegist(string name) 
   { 
   string[] aimnames; 
   RegistryKey hkml = Registry.LocalMachine; 
   RegistryKey software = hkml.OpenSubKey("SOFTWARE",true); 
   RegistryKey aimdir = software.OpenSubKey("XXX",true); 
   aimnames = aimdir.GetSubKeyNames(); 
   foreach(string aimKey in aimnames) 
   { 
   if(aimKey == name) 
   aimdir.DeleteSubKeyTree(name); 
   } 
   } 
   以上是在注册表中HKEY_LOCAL_MACHINE\SOFTWARE目录下XXX目录中删除名称为name注册表项；
    
4. 判断指定注册表项是否存在 
   private bool IsRegeditExit(string name) 
   { 
   bool _exit = false; 
   string[] subkeyNames; 
   RegistryKey hkml = Registry.LocalMachine; 
   RegistryKey software = hkml.OpenSubKey("SOFTWARE",true); 
   RegistryKey aimdir = software.OpenSubKey("XXX",true); 
   subkeyNames = aimdir.GetSubKeyNames(); 
   foreach(string keyName in subkeyNames) 
   { 
   if(keyName == name) 
   { 
   _exit = true; 
   return _exit; 
   } 
   } 
   return _exit; 
   }
