Beispiele

Im folgenden Codebeispiel werden Werte mehrerer Datentypen in einem Beispielschlüssel gespeichert, wobei der Schlüssel in diesem Fall erstellt wird. Anschließend werden die Werte abgerufen und angezeigt. Das Beispiel veranschaulicht das Speichern und Abrufen des (namenlosen) Standardnamen-Wert-Paars und die Verwendung von defaultValue , wenn kein Name-Wert-Paar vorhanden ist.

Hinweise

Ab dem .NET Framework 4 ist der valueName Parameter nicht mehr auf maximal 255 Zeichen beschränkt. Der keyName Parameter hat jedoch weiterhin die Einschränkung von 255 Zeichen.

Da viele Werte in jedem Schlüssel in der Registrierung gespeichert werden können, müssen Sie den valueName Parameter verwenden, um den bestimmten Wert anzugeben, den Sie festlegen möchten.

Wenn valueName im Schlüssel nicht vorhanden ist, wird er erstellt, und der zugeordnete Wert wird auf valuefestgelegt.

Wenn keyName einen nicht vorhandenen Unterschlüssel angibt, wird der Unterschlüssel im angegebenen Stamm erstellt. In Visual Basic erstellt die Zeichenfolge "HKEY_CURRENT_USER\MyTestKey" beispielsweise den Unterschlüssel "MyTestKey" im HKEY_CURRENT_USER Stamm. Die Zeichenfolge "HKEY_CURRENT_USER\MyTestKey\Key2\Key3" erstellt die geschachtelten Unterschlüssel "MyTestKey", "MyTestKey\Key2" und "MyTestKey\Key2\Key3".

Gültige Stammnamen sind HKEY_CURRENT_USER, HKEY_LOCAL_MACHINE, HKEY_CLASSES_ROOT, HKEY_USERS, HKEY_PERFORMANCE_DATA, HKEY_CURRENT_CONFIG und HKEY_DYN_DATA.

Diese Überladung von SetValue speichert 64-Bit-Ganzzahlen als Zeichenfolgen (RegistryValueKind.String). Verwenden Sie die SetValue(String, String, Object, RegistryValueKind) Methodenüberladung, um 64-Bit-Zahlen als RegistryValueKind.QWord Werte zu speichern.

Diese Überladung von SetValue speichert alle Zeichenfolgenwerte als RegistryValueKind.String Objekte, auch wenn sie erweiterbare Verweise auf Umgebungsvariablen enthalten. Verwenden Sie die SetValue(String, String, Object, RegistryValueKind) Methodenüberladung, um Zeichenfolgenwerte als erweiterbare Zeichenfolgen (RegistryValueKind.ExpandString) zu speichern.

Diese Überladung entspricht dem Aufrufen der SetValue(String, String, Object, RegistryValueKind) Methodenüberladung mit RegistryValueKind.Unknown.

' This code example produces output similar to the following:

'NoSuchName: Return this default if NoSuchName does not exist.
'(Default): 5280

'TestArray(0): One

'Use the registry editor to examine the key.
'Press the Enter key to delete the key.

Hinweise

Ab dem .NET Framework 4 ist der valueName Parameter nicht mehr auf maximal 255 Zeichen beschränkt. Der keyName Parameter hat jedoch weiterhin die Einschränkung von 255 Zeichen.

Da viele Werte in jedem Schlüssel in der Registrierung gespeichert werden können, müssen Sie den valueName Parameter verwenden, um den bestimmten Wert anzugeben, den Sie festlegen möchten.

Wenn valueName im Schlüssel nicht vorhanden ist, wird er erstellt, und der zugeordnete Wert wird auf valuefestgelegt.

Wenn keyName einen nicht vorhandenen Unterschlüssel angibt, wird der Unterschlüssel im angegebenen Stamm erstellt. In Visual Basic erstellt die Zeichenfolge "HKEY_CURRENT_USER\MyTestKey" beispielsweise den Unterschlüssel "MyTestKey" im HKEY_CURRENT_USER Stamm. Die Zeichenfolge "HKEY_CURRENT_USER\MyTestKey\Key2\Key3" erstellt die geschachtelten Unterschlüssel "MyTestKey", "MyTestKey\Key2" und "MyTestKey\Key2\Key3".

Gültige Stammnamen sind HKEY_CURRENT_USER, HKEY_LOCAL_MACHINE, HKEY_CLASSES_ROOT, HKEY_USERS, HKEY_PERFORMANCE_DATA, HKEY_CURRENT_CONFIG und HKEY_DYN_DATA.

Wenn der Typ des angegebenen value nicht mit dem angegebenen valueKindübereinstimmt und die Daten nicht konvertiert werden können, ArgumentException wird ausgelöst. Beispielsweise können Sie ein System.Int64 als RegistryValueKind.DWordspeichern, aber nur, wenn sein Wert kleiner als der Maximalwert eines System.Int32ist. Sie können keinen einzelnen Zeichenfolgenwert als RegistryValueKind.MultiStringspeichern.
