Answer 1

There's an example in the .NET SDK called ClipboardSpy.

Here's an example even:

static void Main(string[] args)
{
    while (true)
    {
        if (Clipboard.ContainsText())
        {
            string s = Clipboard.GetText();

            Console.WriteLine(s);

            Clipboard.Clear();
        }
    }
}
