public virtual bool IsSerializable { get; }

Implements

If the current Type represents a constructed generic type, this property applies to the generic type definition from which the type was constructed. For example, if the current Type represents MyGenericType<int> (MyGenericType(Of Integer) in Visual Basic), the value of this property is determined by MyGenericType<T>.

If the current Type represents a type parameter in the definition of a generic type or generic method, this property always returns false.

The following example creates an instance of MyTestClass class, sets the [Serializable] attribute, and checks the IsSerializable property for true or false.

using System;
namespace SystemType
{
    public class MyClass
    {
        // Declare a public class with the [Serializable] attribute.
        [Serializable] public class MyTestClass 
        {
        }
        public static void Main(string []args)
        {
            try
            {
                bool myBool = false;
                MyTestClass myTestClassInstance = new MyTestClass();
                // Get the type of myTestClassInstance.
                Type myType = myTestClassInstance.GetType();
                // Get the IsSerializable property of myTestClassInstance.
                myBool = myType.IsSerializable;
                Console.WriteLine("\nIs {0} serializable? {1}.", myType.FullName, myBool.ToString());
            }
            catch (Exception e)
            {
                Console.WriteLine("\nAn exception occurred: {0}", e.Message);
            }
        }
    }
}
