FieldInfo.IsNotSerialized 屬性

定義

命名空間:

System.Reflection

組件:

netstandard.dll, System.Runtime.dll

來源:

FieldInfo.cs

警告

Formatter-based serialization is obsolete and should not be used.

會得到一個值，表示該欄位是否擁有該 NotSerialized 屬性。

public:
 property bool IsNotSerialized { bool get(); };

[System.Obsolete("Formatter-based serialization is obsolete and should not be used.", DiagnosticId="SYSLIB0050", UrlFormat="https://aka.ms/dotnet-warnings/{0}")]
public bool IsNotSerialized { get; }

[<System.Obsolete("Formatter-based serialization is obsolete and should not be used.", DiagnosticId="SYSLIB0050", UrlFormat="https://aka.ms/dotnet-warnings/{0}")>]
member this.IsNotSerialized : bool

Public ReadOnly Property IsNotSerialized As Boolean

屬性值

Boolean

true 若欄位設定屬性 NotSerialized 為 ;否則， false。

屬性

ObsoleteAttribute

範例

以下範例取得 MyClass 欄位的欄位資訊，判斷欄位是否可序列化，並顯示結果。

using System;
using System.Reflection;
using System.Runtime.Serialization;

public class MyClass
{
    public short myShort;

    // The following field will not be serialized.
    [NonSerialized()]
    public int myInt;
}
public class Type_IsNotSerializable
{
    public static void Main()
    {
        // Get the type of MyClass.
        Type myType = typeof(MyClass);

        // Get the fields of MyClass.
        FieldInfo[] myFields = myType.GetFields(BindingFlags.Public |
            BindingFlags.NonPublic |
            BindingFlags.Instance |
            BindingFlags.Static);
        Console.WriteLine("\nDisplaying whether or not the field is serializable.\n");

        // Display whether or not the field is serializable.
        for(int i = 0; i < myFields.Length; i++)
            if(myFields[i].IsNotSerialized)
                Console.WriteLine("The {0} field is not serializable.", myFields[i]);
            else
                Console.WriteLine("The {0} field is not serializable.", myFields[i]);
    }
}

Imports System.Reflection
Imports System.Runtime.Serialization

<Serializable()> _
Public Class [MyClass]
    Public myShort As Short

    ' The following field will not be serialized.  
    <NonSerialized()> Public myInt As Integer
End Class

Public Class Type_IsNotSerializable

    Public Shared Sub Main()
        ' Get the type of MyClass.
        Dim myType As Type = GetType([MyClass])

        ' Get the fields of MyClass.
        Dim myFields As FieldInfo() = myType.GetFields((BindingFlags.Public Or BindingFlags.NonPublic Or BindingFlags.Instance Or BindingFlags.Static))
        Console.WriteLine(ControlChars.Cr & "Displaying whether or not the field is serializable." & ControlChars.Cr)
        Console.WriteLine()
        ' Displaying whether or not the field is serializable.
        Dim i As Integer
        For i = 0 To myFields.Length - 1
            If myFields(i).IsNotSerialized Then
                Console.WriteLine("The {0} field is not serializable.", myFields(i))
            Else
                Console.WriteLine("The {0} field is serializable.", myFields(i))
            End If
        Next i
    End Sub
End Class

備註

當欄位被標記為旗IsNotSerialized標時，該true屬性會返回FieldAttributes.NotSerialized。 當此標誌設於欄位時，表示該欄位在被遠端存取時不必序列化。
