Inconsistent Accessibility: Parameter type is less

Question

I'm trying to pass an object (a reference to the currently logged on user, basically) between two forms. At the moment, I have something along these lines in the login form:

private ACTInterface oActInterface;

public void button1_Click(object sender, EventArgs e)
    {
        oActInterface = new ACTInterface(@"\\actserver\Database\Premier.pad",this.textUser.Text,this.textPass.Text);

        if (oActInterface.checkLoggedIn())
        {
            //user has authed against ACT, so we can carry on
            clients oClientForm = new clients(oActInterface);
            this.Hide();
            oClientForm.Show();
        }
        else...

on the next form (clients), I have:

public partial class clients : Form
{
    private ACTInterface oActInt {get; set;}

    public clients(ACTInterface _oActInt)

...which results in me getting:

Error   1   Inconsistent accessibility: 
parameter type 'support.ACTInterface' is less accessible than method    
'support.clients.clients(support.ACTInterface)'  
c:\work\net\backup\support\support\clients.cs   20  16  support

I don't really understand what the problem is - both fields are private, and accessed by the relevant public method from the form. Googling doesn't really help, as it just points towards one element being public and the other private, which isn't the case here.

Anybody help?

Answer 1

If sounds like the type ACTInterface is not public, but is using the default accessibility of either internal (if it is top-level) or private (if it is nested in another type).

Giving the type the public modifier would fix it.

Another approach is to make both the type and the method internal, if that is your intent.

The issue is not the accessibility of the field (oActInterface), but rather of the type ACTInterface itself.

Answer 2

The problem doesn't seem to be with the variable but rather with the declaration of ACTInterface. Is ACTInterface declared as internal by any chance?

Answer 3

You can get Parameter (class that have less accessibility) as object then convert it to your class by as keyword.

Answer 4

If this error occurs when you want to use a classvariable in a new form, you should put the class definition in the

Formname.Designer.cs

instead of the Formname.cs file.

Answer 5

After updating my entity framework model, I found this error infecting several files in my solution. I simply right clicked on my .edmx file and my TT file and click "Run Custom Tool" and that had me right again after a restart of Visual Studio 2012.

Answer 6

Make the class public.

class NewClass
{

}

is the same as:

internal class NewClass
{

}

so the class has to be public
