建立 XmlProcessingInstruction 一個名稱和資料。

public:
 virtual System::Xml::XmlProcessingInstruction ^ CreateProcessingInstruction(System::String ^ target, System::String ^ data);
public virtual System.Xml.XmlProcessingInstruction CreateProcessingInstruction(string target, string data);
public virtual System.Xml.XmlProcessingInstruction CreateProcessingInstruction(string target, string? data);
abstract member CreateProcessingInstruction : string * string -> System.Xml.XmlProcessingInstruction
override this.CreateProcessingInstruction : string * string -> System.Xml.XmlProcessingInstruction
Public Overridable Function CreateProcessingInstruction (target As String, data As String) As XmlProcessingInstruction

參數

target
String

處理指令的名稱。

data
String

處理指令的資料。

傳回

XmlProcessingInstruction

新的 XmlProcessingInstruction.

範例

以下範例建立一個 ProcessingInstruction 節點並將其加入文件中。

using System;
using System.IO;
using System.Xml;

public class Sample
{
  public static void Main()
  {
    XmlDocument doc = new XmlDocument();

    // Create a procesing instruction.
    XmlProcessingInstruction newPI;
    String PItext = "type='text/xsl' href='book.xsl'";
    newPI = doc.CreateProcessingInstruction("xml-stylesheet", PItext);

    // Display the target and data information.
    Console.WriteLine("<?{0} {1}?>", newPI.Target, newPI.Data);

    // Add the processing instruction node to the document.
    doc.AppendChild(newPI);
  }
}

Imports System.IO
Imports System.Xml

public class Sample

  public shared sub Main()
  
    Dim doc as XmlDocument = new XmlDocument()

    ' Create a procesing instruction.
    Dim newPI as XmlProcessingInstruction 
    Dim PItext as String = "type='text/xsl' href='book.xsl'"
    newPI = doc.CreateProcessingInstruction("xml-stylesheet", PItext)

    ' Display the target and data information.
    Console.WriteLine("<?{0} {1}?>", newPI.Target, newPI.Data)

    ' Add the processing instruction node to the document.
    doc.AppendChild(newPI)

  end sub
end class

備註

雖然此方法會在文件上下文中建立新物件，但不會自動將新物件加入文件樹。 要新增物件，必須明確呼叫其中一個節點插入方法。

根據 W3C 可擴充標記語言（XML）1.0 建議，ProcessingInstruction 節點僅允許在 Document、Element 和 EntityReference 節點中，且該 EntityReference 節點不是屬性節點的子節點。
