Inconsistent Accessibility Error #2

Question

Help I'm getting this error:

Error 1 Inconsistent accessibility: parameter type 'SharpUpdate.SharpUpdateXml' is less accessible than method 'SharpUpdate.SharpUpdateInfoForm.SharpUpdateInfoForm(SharpUpdate.iSharpUpdateable, SharpUpdate.SharpUpdateXml)'

From this code:

namespace SharpUpdate
{
    public class SharpUpdateInfoForm : Form
    {
        public SharpUpdateInfoForm(
            iSharpUpdateable applicationInfo,
            SharpUpdateXml updateInfo)
        {
            InitializeComponent();
            if (applicationInfo.ApplicationIcon != null)
                this.Icon = applicationInfo.ApplicationIcon;
            this.Text = applicationInfo.ApplicationName + "- Update Info";
            this.lblVersions.Text = String.Format(
                "Current Version:  {0}\nUpdate Version: {1}",
                applicationInfo.ApplicationAssembly.GetName().Version.ToString(),
                updateInfo.Version.ToString());
            this.txtDescription.Text = updateInfo.Description;
        }
    }
}

I've tried changing public to internal and private, but the error remained the same.

Answer 1

Your error is fairly self-explanatory. It boils down to the following:

parameter type SharpUpdateXml is less accessible than method SharpUpdateInfoForm

The SharpUpdateInfoForm is of course the constructor of your form. The constructor is public and the SharpUpdateXml class passsed to the constructor is less accessible (either private or internal). You have to make the SharpUpdateXml class public or SharpUpdateInfoForm internal (or private if SharpUpdateXml is private).

In current scenario you expose your SharpUpdateInfoForm to everyone (public) but to initialize it you have to use SharpUpdateXml which is not available to everyone (private/internal). So a user of your classes can try to initialize the form but may not be allowed to use SharpUpdateXml which makes whole setup bit useless.
