XmlDsigEnvelopedSignatureTransform(Boolean)

Inizializza una nuova istanza della classe XmlDsigEnvelopedSignatureTransform con commenti, se specificato.

public:
 XmlDsigEnvelopedSignatureTransform(bool includeComments);

public XmlDsigEnvelopedSignatureTransform (bool includeComments);

new System.Security.Cryptography.Xml.XmlDsigEnvelopedSignatureTransform : bool -> System.Security.Cryptography.Xml.XmlDsigEnvelopedSignatureTransform

Public Sub New (includeComments As Boolean)

Parametri

includeComments

Boolean

true per includere commenti, in caso contrario, false.

Esempio

Nell'esempio di codice seguente viene illustrato come usare il XmlDsigEnvelopedSignatureTransform costruttore con un Boolean valore di true per includere commenti. Questo esempio di codice fa parte di un esempio più grande fornito per la XmlDsigEnvelopedSignatureTransform classe.

bool IncludeComments = true;
// This transform is created for demonstration purposes.
XmlDsigEnvelopedSignatureTransform^ secondTransform =
    gcnew XmlDsigEnvelopedSignatureTransform(IncludeComments);

bool IncludeComments = true;
// This transform is created for demonstration purposes.
XmlDsigEnvelopedSignatureTransform secondTransform =
    new XmlDsigEnvelopedSignatureTransform(IncludeComments);

Dim IncludeComments As Boolean = True
' This transform is created for demonstration purposes.
Dim secondTransform As _
    New XmlDsigEnvelopedSignatureTransform(IncludeComments)
