Solution: Confidential Documents

Explore how to implement multiple interfaces in C# that share method signatures by using explicit interface implementation. Understand how to design classes like TopSecretBriefing to separately provide printing and encryption logic through interface casting, enabling secure and structured processing of confidential documents.

We'll cover the following...
C# 14.0
namespace Security;
public interface IPrintable
{
    void Process();
}
public interface IEncryptable
{
    void Process();
}
public class TopSecretBriefing : IPrintable, IEncryptable
{
    void IPrintable.Process()
    {
        Console.WriteLine("Printing physical copy...");
    }
    void IEncryptable.Process()
    {
        Console.WriteLine("Encrypting digital file...");
    }
}
