System.MissingM ethodException when calling Private constructor

Hi,

Can anyone advise how to call a private constructor using reflection? I
currently get the above error which is rectified by changing the New() to
Public from Friend but I ideally wish to leave it as Friend to prevent it
being created outside of this project.

Thanks in advance

I mean calling a Friend constructor from another class within the same
project via reflection. Apologies for any confusion with the original post.

hi Rob,

Might help if you show the code you are using. If the type is in the same
assembly, then Activator.Creat eInstance(GetTy pe(foo), true) will work

Hi,

I am using GetType.InvokeM ember with the invokeAttr argument of
Reflection.Bind ingFlags.Create Instance and both classes are in the same VB
2008 project.

It works fine if I change the New() to Public but not whilst it is friend

Thank you

Rob

Hi Rob,

As I suggested earlier, you should use Activator.Creat eInstance(type, True).
InvokeMember ignores other flags if the CreateInstance flag is specified.

I am trying to figure out how to pass set of credentials to System.IO Challenge is: App is running under one set of credentials, but via GUI user have a chance to enter another set. I would like to be able to use supplied credentials with System.IO versus using default credentials that app is running under. So far I am forced to use WMI which is less convenient and slower then System.IO, but it's providing me with "Connection Options"
