I am new to VB.NET. Anyone could give a hint? Thanks.
What is the problem about the following code:

Dim myPrincipal As CustomPrincipal = New CustomPrincipal(id, roles)

where CustomPrincipal is constructor defined as
Public Sub CustomPrincipal(ByVal identity As IIdentity, ByVal roles As
String())

the error message:
Too many arguments to 'Public Sub New()'.
 
A Sub is not a class. The New Operator is for creating instances of classes.

Hi
I am a new ASP.NET programmer

In VB.NET the constructor name should be New and not the class name (C#
constructor name is the class name)

If there is no constructor declared with New keyword then the runtime will
create a default parameterless constructor for you.

So the solution may be:

One: change your constructor name to New instead of CustomPrincipal

Dim myPrincipal As CustomPrincipal = New CustomPrincipal(id, roles)
where CustomPrincipal is constructor defined as
Public Sub New(ByVal identity As IIdentity, ByVal roles As String())
Click to expand...


or

Two create the object without any arguments passed to it


Dim myPrincipal As CustomPrincipal = New CustomPrincipal()
where CustomPrincipal is constructor defined as
Public Sub CustomPrincipal(ByVal identity As IIdentity, ByVal roles As
String())
Click to expand...
 
Hello David,

I think you need to define the constructor as

Public Sub New(ByVal identity As IIdentity, ByVal roles As String())
 
As kevin says, you need to create a constructor...

Publc Sub New(ByVal identity As IIdentity, ByVal roles As String())

perhaps you are used to C# where the constructor is the name of the
class...in VB.Net, you use the New keyword as the constructor name...

Using the name of the class for the constructor is a (C#) language
convention. In VB.NET contrcutors are using always the name "New"...

Try

Dim myPrincipal as New CustomPrincipal(id, roles)

I assume your parameters are of the correct type

Hope that helps
