can you show the Entity class implementation, it could be something in it.

That exception is not being thrown by the line you have shown. It's being thrown when you try to access the Value property of a Nullable<T> type which does not have a value.

Hi All,

@Richard : But that is just object creation right.then y do i get that error.

@Ehsan : Entity class has some properties.like Name,SkU,Weight and it has Serialiazable Attribute.that entity has taken to another project by give the reference.
then i created the object like that .i.e.,
IList<entity> objItems = new List<entity>();

i passed the data to that properties of Entity.after then i added all the data to ILIST entity.
