C# internal interface with internal implementation

Question

I\'ve struck upon something I don\'t really understand.

I have a project, where I have an interface that is internal. The class that implements that interface is als

Answer 1

To all my knowledge you cannot implement interface methods internal. As you stated you can implement them explicitly but then someone can still do ((IScanner)myScanner).SetHardware(hw)

Are you 100% sure your MyScanner implementation does not do something like this:

internal class MyScanner : IScanner
{
    void IScanner.SetHardware(Hardware hardware) { this.SetHardware(hardware); }
    internal void SetHardware(Hardware hardware)
    {
      ...
    }
    ....
}

or this:

internal partial class MyScanner : IScanner
{
    internal void SetHardware(Hardware hardware)
    {
        ...
    }
}

internal partial class MyScanner
{
    void IScanner.SetHardware(Hardware hardware)
    {
        this.SetHardware(hardware);
    }
}
