无法将html格式往返剪贴板

我想写Html格式,但我甚至无法得到一个简单的MSDN示例。

这个控制台应用程序,一个剪贴板往返器,对任何人都有效吗?

using System;
using System.Windows; //Need to add a PresentationCore or System.Windows.Forms reference

class Program {
    [STAThread]
    static void Main( string[] args ) {
        Console.WriteLine( "Copy a small amount of text from a browser, then press enter." );
        Console.ReadLine();

        var text = Clipboard.GetText();
        Console.WriteLine();
        Console.WriteLine( "--->The clipboard as Text:" );
        Console.WriteLine( text );

        Console.WriteLine();
        Console.WriteLine( "--->Rewriting clipboard with the same CF_HTML data." );
        //***Here is the problem code***
        var html = Clipboard.GetText( TextDataFormat.Html );
        Clipboard.Clear();
        Clipboard.SetText( html, TextDataFormat.Html );

        var text2 = Clipboard.GetText();
        Console.WriteLine();
        Console.WriteLine( "--->The clipboard as Text:" );
        Console.WriteLine( text2 );

        var isSameText = ( text == text2 );
        Console.WriteLine();
        Console.WriteLine( isSameText ? "Success" : "Failure" );

        Console.WriteLine();
        Console.WriteLine( "Press enter to exit." );
        Console.ReadLine();
    }
}
