Exempel

I följande exempel hämtas fältinformationen för fälten i MyClass, avgör om fälten kan serialiseras och visar resultatet.

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

        ' 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

Kommentarer

Egenskapen IsNotSerialized returnerar true när fältet är markerat med FieldAttributes.NotSerialized flaggan. När den här flaggan har angetts för ett fält indikerar det att fältet inte behöver serialiseras när typen är fjärransluten.
