Hiermee geeft u opties op voor toepasselijke Split methode-overbelastingen, zoals of lege subtekenreeksen uit de geretourneerde matrix moeten worden weggelaten of witruimte wilt knippen uit subtekenreeksen.

Deze opsomming ondersteunt een bitsgewijze combinatie van de waarden van de leden.

Name Waarde Description
None 0

Gebruik de standaardopties bij het splitsen van tekenreeksen.
RemoveEmptyEntries 1

Weglaten van matrixelementen die een lege tekenreeks uit het resultaat bevatten.

Als RemoveEmptyEntries en TrimEntries samen worden opgegeven, worden subtekenreeksen die alleen uit spatietekens bestaan, ook verwijderd uit het resultaat.
TrimEntries 2

Knip witruimtetekens uit elke subtekenreeks in het resultaat. Dit veld is alleen beschikbaar in .NET 5 en nieuwere versies.

Als RemoveEmptyEntries en TrimEntries samen worden opgegeven, worden subtekenreeksen die alleen uit spatietekens bestaan, ook verwijderd uit het resultaat.

Voorbeelden

In het volgende voorbeeld ziet u hoe de StringSplitOptions opsomming wordt gebruikt om subtekenreeksen op te nemen of uit te sluiten die door de String.Split methode worden gegenereerd:

// This example demonstrates the String.Split() methods that use

Opmerkingen

De String.Split methode retourneert een matrix van de subtekenreeksen in een bepaalde tekenreeks die wordt gescheiden door opgegeven tekens of tekenreeksen. Aangrenzende scheidingstekens leveren een matrixelement op dat een lege tekenreeks ("") bevat. Een van de velden van de StringSplitOptions opsomming geeft aan of een element dat een lege tekenreeks bevat, moet worden opgenomen in de geretourneerde matrix.

Geef het None veld op om het standaardgedrag van de String.Split methode aan te roepen. Dit is niet om spatietekens te knippen en lege subtekenreeksen op te nemen.

Het veld TrimEntries is alleen beschikbaar in .NET 5 en hoger.
