Beschreibung

TFormatSettings definiert einen Thread-sicheren String-Formatierungskontext.

TFormatSettings definiert eine Datenstruktur mit Gebietsschema-Informationen, die von String-Formatierungsroutinen verwendet werden. Jedes Element von TFormatSettings entspricht der gleichnamigen globalen Variable. Eine Variable des Typs TFormatSettings definiert einen Thread-sicheren Kontext, den Formatierungsfunktionen anstelle des globalen Standardkontextes (der nicht Thread-sicher ist) verwenden.

So erstellen und verwenden Sie die von TFormatSettings definierte Thread-sichere Umgebung:

  1. Definieren Sie eine Variable des Typs TFormatSettings.
  2. Rufen Sie TFormatSettings.Create auf, um die Gebietsschema-Informationen in die TFormatSettings-Variable zu schreiben.
  3. Übergeben Sie die TFormatSettings-Variable als letzten Parameter an die String-Formatierungsroutine.

Jede Routine, die einen TFormatSettings-Parameter entgegennimmt, ist Thread-sicher und eine überladene Version der entsprechenden Funktion, in der die globalen Formatierungsvariablen verwendet werden.
