序列化陣列的 XML 元素名稱。 預設名稱為指派的 XmlArrayAttribute 成員名稱。

範例

以下範例序列化一個包含一個屬性的Books類別實例Library，該屬性會回傳一組Book項目。 範例中利用 屬性 ElementName 指定 XML 元素陣列應命名 My_Books ，而非 Books。

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

public class Library
{
   private Book[] books;
   [XmlArray(ElementName="My_Books")]
   public Book[] Books
   {
      get{return books;}
      set{books = value;}
   }
}

public class Book
{
   public string Title;
   public string Author;
   public string ISBN;
}

public class Run
{
   public static void Main()
   {
      Run test = new Run();
      test.WriteBook("ArrayExample.xml");
   }

   public void WriteBook(string filename)
   {
      XmlSerializer mySerializer = new XmlSerializer(typeof(Library));
      TextWriter t = new StreamWriter(filename);
      XmlSerializerNamespaces ns = new XmlSerializerNamespaces();
      ns.Add("bk", "http://wwww.contoso.com");

      Book b1 = new Book();
      b1.Title = "MyBook Title";
      b1.Author = "An Author";
      b1.ISBN = "00000000";

      Book b2 = new Book();
      b2.Title = "Another Title";
      b2.Author = "Another Author";
      b2.ISBN = "0000000";

      Library myLibrary = new Library();
      Book[] myBooks = {b1,b2};
      myLibrary.Books = myBooks;

      mySerializer.Serialize(t,myLibrary,ns);
      t.Close();
   }
}

備註

指定 ElementName 何時產生的 XML 元素名稱與成員識別碼不同。

只要產生的 XML 文件使用 XML 命名空間來區分相同名稱的成員，你可以將相同的 ElementName 值設為多個成員。 關於使用命名空間及在 XML 文件中建立前綴名稱的更多細節，請參見 XmlSerializerNamespaces。
