Conversion of Usercontrol from VB.Net to C#

[Mick Walker]

Hi everyone,

My client is requiring me to convert an existing web app from VB.Net to
C# to become more inline with their existing codebase.

I am running into a problem when converting a usercontrol, basically the
usercontrol has a property which is set by the hosting page, to indicate
if a user is logged in or not. This controls the navigation menu which
the user see's.

In the VB version its just a matter of:
Private _UserIsLoggedIn As Boolean

Public Property UserIsLoggedIn() As Boolean
Get
Return _UserIsLoggedIn
End Get
Set(ByVal value As Boolean)
_UserIsLoggedIn = value
End Set
End Property

So I convert it to C# and this gives me:

private bool _UserIsLoggedIn;

public bool UserIsLoggedIn
{
get { return _UserIsLoggedIn; }
set { _UserIsLoggedIn = value; }
}

However, I cannot access this property from the calling page.

Can anyone tell me where I am going wrong.

Regards

if you want to access this property after creating the instance of the
class.there must be nothing wrong.But if you want to access it wlthout
creating instance ,you must use 'static'.But convertion to c# and the
piece of code is true, you will access the property after creating the
instance..if you send more part of code ,we can help you more..

Do you cast the user control variable to the proper type ? Remember that C#
is always in "option strict on" mode (and you may want to do the same in
your VB projects).

The answer is that you have changed the visibility of your property. In the
VB code you have defined it as Public, whereas you have used the private
keyword in the C# code. Change private to public and it will be visible.

I'd hate to state the obvious - but have you rebuilt the entire
project yet? Also, close all the tabs in the IDE and then reopen them.
C# and Asp.Net sometimes have difficulties keeping Intellisense up-to-
date. For C# you often must rebuild the project to get some changes to
show up, and with Asp.Net Intellisense sometimes won't refresh until
the code behind file has been reloaded.

Thanks,

That's not the case here - in both the VB and C# versions, the field is
private and the property is public.

Here is the code for my user control if that helps:

[...]
public static bool UserIsLoggedIn

Um. Your original example showed an instance property, but the above
shows a static property.

First, you should know that a static property is shared among all
instances of the same class. Second, you should know that to access a
static property, you need to specify the class name, not an instance
name. That is:

Controls_uc_MainMenu.UserIsLoggedIn;

Rather than:

MainMenu1.UserIsLoggedIn;

Do you really intend for the properties to be static?

You didn't read the code or the previous posts very well did you? The
OP defined the variable to be returned as private and the property as
public so everything is fine. Second, David Anton has already
corrected another poster who said the same thing you just did...

Thanks,
