XmlDeclaration.Standalone 屬性

定義

命名空間:

System.Xml

組件:

System.Xml.dll, System.Xml.XmlDocument.dll

組件:

System.Xml.ReaderWriter.dll

組件:

System.Xml.XmlDocument.dll

組件:

System.Xml.dll

組件:

netstandard.dll

取得或設定獨立屬性的值。

public:
 property System::String ^ Standalone { System::String ^ get(); void set(System::String ^ value); };

public string Standalone { get; set; }

member this.Standalone : string with get, set

Public Property Standalone As String

屬性值

String

如果 XML 文件所需的所有實體宣告都包含在文件中，其有效值為 yes；如果需要外部文件類型定義 (DTD)，則有效值為 no。 如果在 XML 宣告中沒有獨立屬性，這個屬性會傳回 String.Empty。

範例

下列範例會 XmlDeclaration 建立節點，並將其新增至 XML 檔。

#using <System.Xml.dll>

using namespace System;
using namespace System::IO;
using namespace System::Xml;
int main()
{
   
   // Create and load the XML document.
   XmlDocument^ doc = gcnew XmlDocument;
   String^ xmlString = "<book><title>Oberon's Legacy</title></book>";
   doc->Load( gcnew StringReader( xmlString ) );
   
   // Create an XML declaration. 
   XmlDeclaration^ xmldecl;
   xmldecl = doc->CreateXmlDeclaration( "1.0", nullptr, nullptr );
   xmldecl->Encoding = "UTF-8";
   xmldecl->Standalone = "yes";
   
   // Add the new node to the document.
   XmlElement^ root = doc->DocumentElement;
   doc->InsertBefore( xmldecl, root );
   
   // Display the modified XML document 
   Console::WriteLine( doc->OuterXml );
}
