定義

命名空間:

System.Xml.Serialization

組件:

System.Xml.XmlSerializer.dll

初始化 XmlArrayAttribute 類別的新執行個體。

多載

XmlArrayAttribute()	初始化 XmlArrayAttribute 類別的新執行個體。
XmlArrayAttribute(String)	初始化 XmlArrayAttribute 類別的新執行個體，指定 XML 文件執行個體中產生的 XML 項目名稱。

XmlArrayAttribute()

來源:

XmlArrayAttribute.cs

初始化 XmlArrayAttribute 類別的新執行個體。

public:
 XmlArrayAttribute();

public XmlArrayAttribute ();

Public Sub New ()

範例

下列範例會將 XmlArrayAttribute 指派給兩個數組。

public ref class MyClass
{
public:

   [XmlArrayAttribute]
   array<String^>^MyStringArray;

   [XmlArrayAttribute]
   array<Int32>^MyIntegerArray;
};

public class MyClass
{
    [XmlArrayAttribute()]
    public string [] MyStringArray;
    [XmlArrayAttribute()]
    public int [] MyIntegerArray;
}

Public Class MyClass1
    <XmlArrayAttribute()> Public MyStringArray() As String
    <XmlArrayAttribute()> Public MyIntegerArray() As Integer
End Class

XmlArrayAttribute(String)

來源:

XmlArrayAttribute.cs

初始化 XmlArrayAttribute 類別的新執行個體，指定 XML 文件執行個體中產生的 XML 項目名稱。

public:
 XmlArrayAttribute(System::String ^ elementName);

public XmlArrayAttribute (string? elementName);

new System.Xml.Serialization.XmlArrayAttribute : string -> System.Xml.Serialization.XmlArrayAttribute

Public Sub New (elementName As String)

參數

elementName

String

XmlSerializer 產生的 XML 項目名稱。
