Hi all,
I'm still rather new to .NET so I hope you'll bear with me as I try and explain
my question.
I am writing an ASP.NET application using VB.NET. I am accessing a web method
from a webservice that returns a structure. On the client side I have added the
webservice as a reference and created a class that contains the structure as a
member as well as some other variables. The structure looks something like:
Public Structure ValuationResult
Dim Reliability As Integer
Dim ShowClientID As String
Dim ShowDepartment As String
Dim ShowSource As String
Dim Valuation As ValuationStructure 'another structure
End Structure
And the class I'm creating looks like:
Public Class Report
Private _ID As Integer
Private _ValuationResult As myWebservice.ValuationResult
Public Property ID as integer
Get
Return _ID
End Get
Set(ByVal Value As Integer)
_ID = Value
End Set
End Property
Public Property ValuationResult as myWebservice.ValuationResult
Get
Return _ValuationResult
End Get
Set(ByVal Value as myWebservice.ValuationResult)
_ValuationResult = Value
End Set
End Property
...
End Class
I am now trying to create a constructor that will allow the user to pass the
populated structure that I get back from the webservice and populate the
appropriate fields. After some trial and error I've come up with:
Public Sub New(ByVal Result As myWebservice.ValuationResult)
ValuationResult = New myWebservice.ValuationResult
Me.ValuationResult.Reliability = Result.Reliability
Me.ValuationResult.ShowClientID = Result.ShowClientID
Me.ValuationResult.ShowDepartment = Result.ShowDepartment
Me.ValuationResult.ShowSource = Result.ShowSource
ValuationResult.Valuation = New myWebservice.Valuation
Me.ValuationResult.Valuation.FSA = Result.Valuation.FSA
Me.ValuationResult.Valuation.PID = Result.Valuation.PID
...
End Sub
Now this seems to work when I call the constructor but I am unclear exactly as
to why I need to call New for the structures and any structures contained within
the parent struct. Afterall, they are strucutures and not classes. Is it
because the struct is part of the class and no memory has yet been allocated for
it until I call New?
Also, is this the best way of doing this? Is there another more elegant way?
Thanks for your help.
