 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)

パラメーター

includeComments

例

次のコード例では、 の値trueを持つコンストラクターをXmlDsigEnvelopedSignatureTransform使用してコメントをBoolean含める方法を示します。 このコード例は、XmlDsigEnvelopedSignatureTransform クラスのために提供されている大規模な例の一部です。

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)
