FieldInfo.IsNotSerialized Property

Gets a value indicating whether this field has the NotSerialized attribute.

Namespace: System.Reflection
Assembly: mscorlib (in mscorlib.dll)

public bool IsNotSerialized { get; }
/** @property */
public final boolean get_IsNotSerialized ()

public final function get IsNotSerialized () : boolean

Property Value

true if the field has the NotSerialized attribute set; otherwise, false.

The IsNotSerialized property returns true when the field is marked with the FieldAttributes.NotSerialized flag. When this flag is set on a field, it indicates that the field does not have to be serialized when the type is remoted.

The following example gets the field information of the fields of MyClass, determines if the fields can be serialized, and displays the results.

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]);
    }
}
