IsNormalized()

- Quelle:

Gibt an, ob diese Zeichenfolge in der Unicode-Normalisierungsform C vorliegt.
public:
bool IsNormalized();
public bool IsNormalized ();
member this.IsNormalized : unit -> bool
Public Function IsNormalized () As Boolean
Gibt zurück
true
, wenn diese Zeichenfolge in der Normalisierungsform C vorliegt; andernfalls false
.
Ausnahmen
Die aktuelle Instanz enthält ungültige Unicode-Zeichen.
Hinweise
Einige Unicode-Zeichen verfügen über mehrere gleichwertige binäre Darstellungen, die aus Kombinations- und/oder zusammengesetzten Unicode-Zeichen bestehen. Das Vorhandensein mehrerer Darstellungen für ein einzelnes Zeichen erschwert die Suche, Sortierung, Abgleich und andere Vorgänge.
Der Unicode-Standard definiert einen Prozess namens Normalisierung, der eine binäre Darstellung zurückgibt, wenn eine der entsprechenden binären Darstellungen eines Zeichens angegeben wird. Die Normalisierung kann mit mehreren Algorithmen, sogenannten Normalisierungsformen, durchgeführt werden, die unterschiedlichen Regeln entsprechen. .NET unterstützt derzeit die Normalisierungsformulare C, D, KC und KD.
Eine Beschreibung der unterstützten Unicode-Normalisierungsformulare finden Sie unter System.Text.NormalizationForm.
Hinweise für Aufrufer
Die IsNormalized -Methode gibt zurück false
, sobald sie auf das erste nicht normalisierte Zeichen in einer Zeichenfolge trifft. Wenn eine Zeichenfolge daher nicht normalisierte Zeichen enthält, gefolgt von ungültigen Unicode-Zeichen, löst die Normalize -Methode einen aus ArgumentException , obwohl IsNormalized zurückgibt false
.
