New Feature, VisualBasic With Keyword Syntax for property mapping

[xieguigang]

Hi, currently, if we want to get or set property value to another object, 7 lines of code must be used,

Current:

Dim _value As <Value>

Public Property Value As String
Get
    Return _value.Label
End Get
Set
    _value.Label = value
End Set

This is not so convenient and not a brief code, and I think this situation can be simplify with the VisualBasic With keyword

Dim _value As <Value>

' maps both get and set
Public Property Value As String With _value.Label
' maps readonly
Public ReadOnly Property Value2 As String With _value.Label
' maps writeonly
Public WriteOnly Property Value3 As String With _value.Label

Or with two lines of code syntax

Dim _value As <Value>

' maps both get and set
Public Property Value As String 
    With _value.Label

' maps readonly
Public ReadOnly Property Value2 As String 
    With _value.Label

' maps writeonly
Public WriteOnly Property Value3 As String 
    With _value.Label

Which it means the Value property its value was mapped to the property of another object _value.Label, this will makes the code more beautiful and briefly.

This can compined with #403 to bind an expression or block of code:

Public ReadOnly Property Sum() string With {
   Dim _sum = 0
   For each .....
      _sum+= .......
   Next 
   Return _sum}
End Property

Or it can compined with #422 :

Public ReadOnly Property Sum() string With <(
   Dim _sum = 0
   For each .....
      _sum+= .......
   Next 
   Return _sum)>
