public System.Xml.XmlAttribute RemoveAt (int i);

public System.Xml.XmlAttribute? RemoveAt (int i);

public virtual System.Xml.XmlAttribute RemoveAt (int i);

member this.RemoveAt : int -> System.Xml.XmlAttribute

abstract member RemoveAt : int -> System.Xml.XmlAttribute
override this.RemoveAt : int -> System.Xml.XmlAttribute

Public Function RemoveAt (i As Integer) As XmlAttribute

Public Overridable Function RemoveAt (i As Integer) As XmlAttribute

参数

i: Int32

要删除的节点的索引。第一个节点的索引为 0。

示例

以下示例从文档中删除一个属性。

#using <System.Xml.dll>

using namespace System;
using namespace System::IO;
using namespace System::Xml;
int main()
{
   XmlDocument^ doc = gcnew XmlDocument;
   doc->LoadXml( "<book genre='novel' ISBN='1-861001-57-5'><title>Pride And Prejudice</title></book>" );
   
   //Create an attribute collection and remove an attribute
   //from the collection.
   XmlAttributeCollection^ attrColl = doc->DocumentElement->Attributes;
   attrColl->RemoveAt( 0 );
   Console::WriteLine( "Display the modified XML...\r\n" );
   Console::WriteLine( doc->OuterXml );
}

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

public class Sample
{
  public static void Main(){

                "</book>");

    //Create an attribute collection and remove an attribute
    //from the collection.
    XmlAttributeCollection attrColl = doc.DocumentElement.Attributes;
    attrColl.RemoveAt(0);

    Console.WriteLine("Display the modified XML...\r\n");
    Console.WriteLine(doc.OuterXml);
  }
}

Imports System.IO
Imports System.Xml

public class Sample

  public shared sub Main()

    'Create an attribute collection and remove an attribute
    'from the collection.  
    Dim attrColl as XmlAttributeCollection = doc.DocumentElement.Attributes
    attrColl.RemoveAt(0)

    Console.WriteLine("Display the modified XML...")
