XmlAttributes.XmlType 屬性

定義

命名空間:

System.Xml.Serialization

組件:

netstandard.dll, System.Xml.XmlSerializer.dll

來源:

XmlAttributes.cs

取得或設定一個物件，指定如何 XmlSerializer 序列化已套用的 XmlTypeAttribute 類別。

public:
 property System::Xml::Serialization::XmlTypeAttribute ^ XmlType { System::Xml::Serialization::XmlTypeAttribute ^ get(); void set(System::Xml::Serialization::XmlTypeAttribute ^ value); };

public System.Xml.Serialization.XmlTypeAttribute? XmlType { get; set; }

member this.XmlType : System.Xml.Serialization.XmlTypeAttribute with get, set

Public Property XmlType As XmlTypeAttribute

屬性值

XmlTypeAttribute

一個 XmlTypeAttribute 能覆蓋 並 XmlTypeAttribute 套用到 class 聲明的 。

範例

以下範例建立一個 XmlTypeAttribute 物件，並將其指派給 XmlType 物件 XmlAttributes 的屬性。

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

public class Transportation
{
   public Car[] Cars;
}

public class Car
{
   public int ID;
}

public class Test
{
   public static void Main()
   {
      Test t = new Test();
      t.SerializeObject("XmlType.xml");
   }

   // Return an XmlSerializer used for overriding.
   public XmlSerializer CreateOverrider()
   {
      // Create the XmlAttributes and XmlAttributeOverrides objects.
      XmlAttributes attrs = new XmlAttributes();
      XmlAttributeOverrides xOver = new XmlAttributeOverrides();

      /* Create an XmlTypeAttribute and change the name of the
         XML type. */
      XmlTypeAttribute xType = new XmlTypeAttribute();
      xType.TypeName = "Autos";

      // Set the XmlTypeAttribute to the XmlType property.
      attrs.XmlType = xType;

      /* Add the XmlAttributes to the XmlAttributeOverrides,
         specifying the member to override. */
      xOver.Add(typeof(Car), attrs);

      // Create the XmlSerializer, and return it.
      XmlSerializer xSer = new XmlSerializer
      (typeof(Transportation), xOver);
      return xSer;
   }

   public void SerializeObject(string filename)
   {
      // Create an XmlSerializer instance.
      XmlSerializer xSer = CreateOverrider();

      // Create object and serialize it.
      Transportation myTransportation =
      new Transportation();

      Car c1 = new Car();
      c1.ID = 12;

      Car c2 = new Car();
      c2.ID = 44;

      myTransportation.Cars = new Car[2]{c1,c2};

      // To write the file, a TextWriter is required.
      TextWriter writer = new StreamWriter(filename);
      xSer.Serialize(writer, myTransportation);
   }
}

Imports System.IO
Imports System.Xml.Serialization


Public Class Transportation
    Public Cars() As Car

    Public ID As Integer

    Public Function CreateOverrider() As XmlSerializer

        Dim attrs As New XmlAttributes()
        Dim xOver As New XmlAttributeOverrides()

        ' XML type. 
        Dim xType As New XmlTypeAttribute()
        xType.TypeName = "Autos"
        
        ' Set the XmlTypeAttribute to the XmlType property.
        attrs.XmlType = xType
        
        ' Add the XmlAttributes to the XmlAttributeOverrides,
        ' specifying the member to override. 
        xOver.Add(GetType(Car), attrs)
        
        ' Create the XmlSerializer, and return it.
        Dim xSer As New XmlSerializer(GetType(Transportation), xOver)
        Return xSer
    End Function
    
    
    Public Sub SerializeObject(ByVal filename As String)
        ' Create an XmlSerializer instance.
        Dim xSer As XmlSerializer = CreateOverrider()
        
        ' Create an object and serialize it.
        Dim myTransportation As New Transportation()
        
        Dim c1 As New Car()
        c1.ID = 12
        
        Dim c2 As New Car()
        c2.ID = 44
        
        myTransportation.Cars = New Car(1) {c1, c2}
        
        ' To write the file, a TextWriter is required.
        Dim writer As New StreamWriter(filename)
        xSer.Serialize(writer, myTransportation)
    End Sub
End Class

備註

可用XmlTypeAttribute來控制型別如何被序列化。XmlSerializer 例如，預設情況下，當型別被序列化時，會 XmlSerializer 使用類別名稱作為 XML 元素名稱。 透過建立 XmlTypeAttribute一個 ，設定 XmlType 屬性，並建立 XmlAttributeOverrides 物件，你可以更改 XML 元素名稱。
