public:
 XmlArrayAttribute(System::String ^ elementName);

public XmlArrayAttribute (string elementName);

public XmlArrayAttribute (string? elementName);

new System.Xml.Serialization.XmlArrayAttribute : string -> System.Xml.Serialization.XmlArrayAttribute

Public Sub New (elementName As String)

Parametry

elementName

String

Název elementu XML, který generuje XmlSerializer .
