LineItem Constructor (SerializationInfo, StreamingContext)
Initializes a new instance of the LineItem class based on the specified serialization information and streaming context.
Namespace: Microsoft.CommerceServer.Runtime.Orders
Assembly: Microsoft.CommerceServer.Runtime (in Microsoft.CommerceServer.Runtime.dll)

)
protected:

context : StreamingContext
)
Parameters
- info
Type: System.Runtime.Serialization..::.SerializationInfo
The SerializationInfo used to retrieve data.
- context
Type: System.Runtime.Serialization..::.StreamingContext
The StreamingContext used for this serialization.
Exceptions
| Exception | Condition |
|---|---|
| InvalidCastException | The data you are using to deserialize from potentially does not have the same fields or field types as the existing runtime object. This could indicate a version mismatch between the runtime objects and the stored data. |
| SerializationException | There was a version mismatch between the data being deserialized and the current runtime object. |
Remarks
This constructor is marked protected so it can be called from derived a class's deserialization constructors to ensure that deserialization succeeds. This constructor must be called from a derived class's deserialization constructor to ensure that deserialization succeeds.
LineItem represents a single line item. LineItem implements IEnumerable to allow easy enumeration over all weakly-typed properties of the line item.
The order capture system assigns a unique integer to every line item for every OrderForm. Upon removal of an item, these integer index values are recomputed. Line items are created as stand-alone entities, and are then added to the LineItemCollection.
