Another post back,

A top after a class definition of each attribute, more members, directly calculate the value of the attributes of other,

Set the set the get 2 indexer permissions,

reference Amon, 4/f, Amon response:

borrow # 1/f, changed the code, I feel should be more in line with coding standards and proposals:

 
Public class BillModel 
{
///& lt; Summary> 
///unit price 
///& lt;/summary> 
Public decimal Price {get; The set; } 
///& lt; Summary> 
///quantity 
///& lt;/summary> 
Public decimal Count {get; The set; } 

///& lt; Summary> 
///discount 
///& lt;/summary> 
Public decimal Discount 
{
The get 
{
If (IsPromotion) 
The return of 0.6 M; 

The switch (MemberType) 
{
Case VIPType. Golden: 
The return of 0.9 M; 
Case VIPType. Platinum: 
The return of 0.8 M; 
Default: 
The return of 1.0 M; 
} 
} 
} 

///& lt; Summary> 
///amount 
///& lt;/summary> 
Public decimal Account 
{
The get 
{
Return the Discount Price * * Count; 
} 

} 
///& lt; Summary> 
///occurrence date 
///& lt;/summary> 
Public DateTime Date {get; The set; } 

///& lt; Summary> 
///whether discount 
///& lt;/summary> 
Public bool IsPromotion {get; The set; } 

///& lt; Summary> 
///member types: 0 regular members, member of 1 gold, 2 platinum 
///& lt;/summary> 
Public VIPType MemberType {get; The set; } 
} 

Public enum VIPType 
{
Normal=0, 
Golden=1, 
Platinum=2, 
} 

Can, and the best encapsulation attribute permissions, good design,
