The WrongTypeException will always be thrown if your object implements the ICreateObject interface, but does not create the expected object type as the result value.

Here’s an example for this:

    /// <summary>

    /// This class creates the wrong object type and causes the WrongTypeException

    /// </summary>

    public class WrongType : BaseVO, ICreateObject

    {

        private int number;

        /// <summary>

        /// Gets or sets the number.

        /// </summary>

        /// <value>The number.</value>

        [PropertyName("IntNumber")]

        public int Number

        {

            get { return number; }

            set { number = value; }

        }

        /// <summary>

        /// Creates the new object.

        /// </summary>

        /// <returns></returns>

        public IValueObject CreateNewObject()

        {

            return new NullValue();

        }

    }
