wpf - 如何在 WPF 中使用 Ink 识别？

Question

我正在使用.Net 4.0 WPF。我想使用 InkCanvas 来收集用户输入，然后识别输入了什么字符。谷歌搜索后，我在http://msdn.microsoft.com/zh-cn/library/ms754080.aspx找到了解决方案， 不幸的是，它适用于 .net 3.5。.net 4.0 有解决方案吗？谢谢。

====================

从http://www.microsoft.com/en-us/download/details.aspx?id=20989下载 TablePC SDK， 然后获得 Micorsoft.Ink.dll。下面是示例代码...

    using Microsoft.Ink;
    using System.IO;
    private void btnGetInput_Click(object sender, RoutedEventArgs e)
    {
        if (inkInput.Strokes.Count > 0)
        {
            System.Windows.Ink.StrokeCollection strokeList = inkInput.Strokes;

            MemoryStream ms = new MemoryStream();
            inkInput.Strokes.Save(ms);
            InkCollector myInkCollector = new InkCollector();
            Ink ink = new Ink();
            ink.Load(ms.ToArray());

            using (RecognizerContext myRecoContext = new RecognizerContext())
            {
                RecognitionStatus status;
                RecognitionResult recoResult;
                myRecoContext.Strokes = ink.Strokes;
                recoResult = myRecoContext.Recognize(out status);
                tbUserName.Text += recoResult.TopString;
            }
            inkInput.Strokes.Clear();
        }
    }
