示例

下面的代码示例演示如何在远程计算机上打开注册表项并枚举密钥的值。 远程计算机必须运行远程注册表服务。 在调用程序时，将远程计算机的名称指定为命令行参数。

using namespace System;
using namespace System::IO;
using namespace System::Security::Permissions;
using namespace Microsoft::Win32;


int main( int argc, char *argv[] )
{
   RegistryKey ^ environmentKey;
   
   // Check that an argument was specified when the 
   // program was invoked.
   if ( argc == 1 )
   {
      Console::WriteLine( "Error: The name of the remote computer "
      "must be specified as input on the command line." );
      return  -1;
   }

   try
   {
      
      // Open HKEY_CURRENT_USER\Environment on a remote computer.
      environmentKey = RegistryKey::OpenRemoteBaseKey( RegistryHive::CurrentUser, gcnew String(argv[ 1 ]) )->OpenSubKey( "Environment" );
   }
   catch ( IOException^ e ) 
   {
      Console::WriteLine(  "{0}: {1}", e->GetType()->Name, e->Message );
      return  -1;
   }

   
   // Print the values.
   Console::WriteLine( "\nThere are {0} values for {1}.", environmentKey->ValueCount.ToString(), environmentKey->Name );
   array<String^>^valueNames = environmentKey->GetValueNames();
   for ( int i = 0; i < environmentKey->ValueCount; i++ )
   {
      Console::WriteLine(  "{0,-20}: {1}", valueNames[ i ], environmentKey->GetValue( valueNames[ i ] )->ToString() );

   }
   
   // Close the registry key.
   environmentKey->Close();
}

                RegistryHive.CurrentUser, remoteName).OpenSubKey(
                "Environment");
        }
        catch(IOException e)
        {
            Console.WriteLine("{0}: {1}",

注解

RegistryHive 方法使用 OpenRemoteBaseKey 值来表示外部 (远程) 计算机上的所请求密钥的顶级节点。 可以使用 OpenRemoteBaseKey 方法打开的节点必须是这些顶级 的其中一个。RegistryKeys 只要用户具有适当的权限，即可使用 中的 RegistryKey方法进一步访问标识的节点的子项。
