.Net Micro Framework研究—窗体控件

 试验平台：.Net Micro Framework 模拟器 在Microsoft.SPOT.Presentation.Controls命名空间里，也就如下几个控件（姑且称为控件吧），Panel、StackPanel、Text、TextFlow、Image、ListBox、ScrollViewer 其中仅有Panel、Text、Image控件完成度相对较好，其他的实现并不完整，甚至只是一个空接口。下面是测试代码：using System;using Microsoft.SPOT;using Microsoft.SPOT.Input;using Microsoft.SPOT.Presentation;using Microsoft.SPOT.Presentation.Controls;using Microsoft.SPOT.Presentation.Media;using Microsoft.SPOT.Presentation.Shapes; namespace MFWindow{    public class Program : Microsoft.SPOT.Application    {        public static void Main()        {               //创建窗体            WindowsDrawing win = new WindowsDrawing();                      //程序运行            new Program().Run(win);        }                internal sealed class WindowsDrawing : Window        {            public  WindowsDrawing()            {                this.Width = SystemMetrics.ScreenWidth;                this.Height = SystemMetrics.ScreenHeight;                 //可设置显示方向（水平，垂直）                //StackPanel panel = new StackPanel(Orientation.Vertical);                StackPanel panel = new StackPanel(Orientation.Horizontal);                                //设置对象堆叠的方式                panel.HorizontalAlignment = HorizontalAlignment.Left;                panel.VerticalAlignment = VerticalAlignment.Top;                                           this.Child = panel;                 //Text控件                Text txt = new Text(Resources.GetFont(Resources.FontResources.small), "yefan");                txt.Width = 100;                txt.Height = 30;                txt.ForeColor = Colors.Green;                     panel.Children.Add(txt);                 //TextFlow控件 不支持滚动条，实现还不完整                TextFlow txtf = new TextFlow();                txtf.ScrollingStyle = ScrollingStyle.LineByLine;                txtf.TextAlignment = TextAlignment.Left;                txtf.Height = 200;                txtf.Width = 50;                             for (int i = 0; i < 10; i++)                {                    txtf.TextRuns.Add(new TextRun("yefan123", Resources.GetFont(Resources.FontResources.small), Colors.Blue));                    //注意:换行这么写，可不是/r/n                    txtf.TextRuns.Add(TextRun.EndOfLine);                    txtf.TextRuns.Add(new TextRun("yefan456", Resources.GetFont(Resources.FontResources.small), Colors.Red));                    txtf.TextRuns.Add(TextRun.EndOfLine);                    txtf.TextRuns.Add(new TextRun("yefan789", Resources.GetFont(Resources.FontResources.small), Colors.Green));                    txtf.TextRuns.Add(TextRun.EndOfLine);                }                panel.Children.Add(txtf);                          //image                Image img = new Image();                img.Bitmap = Resources.GetBitmap(Resources.BitmapResources.yfmvp);                panel.Children.Add(img);                 //ListBox  仅实现了一个空接口                ListBox lst = new ListBox();                lst.Font = Resources.GetFont(Resources.FontResources.small);                lst.Items.Add(new ListBoxItem());                //panel.Children.Add(lst);                 //ScrollViewer 仅实现了一个空接口                ScrollViewer sv = new ScrollViewer();                sv.Width = 30;                sv.Height = 50;                //panel.Children.Add(sv);                       //sv.Child = txtf;                            }        }    }}

目前版本的MF对TCP协议栈支持也并不完善（对串口也谈不上完善，毕竟不支持奇偶校验、停止位设置），Digi的以太网口是加入了自己的处理方案，明年二月份微软将要发布的MF V3.0版，就已经完全支持TCP了，到时候MF最理想的应用也许就是通信转换了。从本篇内容中可以看出，微软MF之旅尚在出发点不远的地方，MF研发人员任重而道远啊！
