IdnMapping.GetUnicode Methode

public:
 System::String ^ GetUnicode(System::String ^ ascii);

public string GetUnicode(string ascii);

member this.GetUnicode : string -> string

Public Function GetUnicode (ascii As String) As String

Parameters

Retouren

Het Unicode-equivalent van de IDNA-subtekenreeks die is opgegeven door de ascii parameter.

Voorbeelden

In het volgende voorbeeld wordt de GetAscii(String) methode gebruikt om een matrix met geinternationaliseerde domeinnamen te converteren naar Punycode. De GetUnicode(String) methode converteert vervolgens de Punycode-domeinnaam terug naar de oorspronkelijke domeinnaam, maar vervangt de oorspronkelijke labelscheidingstekens door het standaardlabelscheidingsteken.
