RegistryKey.CreateSubKey 方法

Source:

RegistryKey.cs

public:
 Microsoft::Win32::RegistryKey ^ CreateSubKey(System::String ^ subkey);

public Microsoft.Win32.RegistryKey CreateSubKey(string subkey);

member this.CreateSubKey : string -> Microsoft.Win32.RegistryKey

Public Function CreateSubKey (subkey As String) As RegistryKey

参数

返回

新建的子项，或者 null 操作失败。 如果指定 subkey了零长度字符串，则返回当前 RegistryKey 对象。

例外

示例

下面的代码示例演示如何在HKEY_CURRENT_USER下创建子项，操作其内容，然后删除子项。

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

   test9999->CreateSubKey( "TestName" )->Close();
   RegistryKey ^ testSettings = test9999->CreateSubKey( "TestSettings" );

   // Create data for the TestSettings subkey.
   testSettings->SetValue( "Language", "French" );
   testSettings->SetValue( "Level", "Intermediate" );
   testSettings->SetValue( "ID", 123 );
   testSettings->Close();

   // Print the information from the Test9999 subkey.
   Console::WriteLine( "There are {0} subkeys under Test9999.", test9999->SubKeyCount.ToString() );

注解

该方法 CreateSubKey 创建具有参数指定的访问控制的 registrySecurity 注册表项。 RegistryKey返回的对象表示注册表项，但该对象不受参数中指定的registrySecurity访问控制的限制。

permissionCheck如果是RegistryKeyPermissionCheck.ReadWriteSubTree，则打开密钥进行读/写访问。 permissionCheck如果是RegistryKeyPermissionCheck.ReadSubTree，则打开密钥进行读取访问。

为了向后兼容，将打开密钥进行读取和写入（如果是permissionCheckRegistryKeyPermissionCheck.Default）并且父键也具有RegistryKeyPermissionCheck.Default。 如果父密钥具有任何其他设置，则读/写状态由父密钥的设置控制。

若要执行此操作，用户必须在注册表层次结构中具有此级别和更低级别的权限。
