原来Mock可以这样子用。

1.   接口ISerialPort

    public interface ISerialPort
    {
        string PortName { get; }
        int BaudRate { get; }
        int DataBits { get; }
        Parity Party { get; }
        StopBits StopBits { get; }
        int BytesToRead { get; }
        bool IsOpen { get; }
        void Open();
        void Close();
        string ReadLine();
        int ReadByte();
        int Read(ref byte[] buffer, int offset, int count);
        string ReadTo(string p);
        void Write(byte[] data, int offset, int count);
    }

2. 用Rhino Mock测试串口

        [TestMethod()]
        public void ReadAlarmTest()
        {
            MockRepository mock = new MockRepository();
            ISerialPort serialPort = mock.StrictMock<ISerialPort>();
            VSerialPort target = new VSerialPort(serialPort);
            string excepted ="1,1,1,";
            string actual = string.Empty;
            StringBuilder sb = new StringBuilder();
            target.OnReceiveData += (alarmNo) =>{ sb.Append(alarmNo);sb.Append(',');};
            using (mock.Record())
            {
                byte[] data = GetAlarmData();
                byte[] outData = new byte[data.Length];
                serialPort.Expect(p => p.ReadByte()).Return(0x21);
                serialPort.Expect(p => p.Write(new byte[] {1,0x64,0x0D}, 0, 3));
                serialPort.Expect(p => p.BytesToRead).Return(data.Length);
                serialPort.Expect(p => p.Read(ref outData, 0, outData.Length)).OutRef(data).Return(data.Length);
                serialPort.Expect(p => p.BytesToRead).Return(0);
            }
            target.ReadAlarm();
            actual = sb.ToString();
            Assert.AreEqual(excepted, actual);
        }
        
        static byte[] GetAlarmData()
        {
            List<byte> data = new List<byte>();
            data.Add(1);
            data.AddRange(Encoding.ASCII.GetBytes("ALARM MON #01=001 \r\n$\r\n"));
            data.Add(1);
            data.AddRange(Encoding.ASCII.GetBytes("ALARM MON #01=001 \r\n$\r\n"));
            data.Add(1);
            data.AddRange(Encoding.ASCII.GetBytes("ALARM MON #01=001 \r\n$\r\n"));
            data.Add(1);
            data.AddRange(Encoding.ASCII.GetBytes("$\r"));
            data.Add(1);
            data.AddRange(Encoding.ASCII.GetBytes("000\r\n"));
            return data.ToArray();
        }

AdventureWorksLT2008Entities db = new AdventureWorksLT2008Entities();
 
 var querys = db.Products.Where(p => p.ProductID % 55 == 0).Select(p => new { Id = p.ProductID, LPrice = p.ListPrice, Name = p.Name });

 foreach (var item in querys)
 {
     Console.WriteLine(item.Id+". "+item.LPrice+" "+item.Name);
 }

 Console.WriteLine(((System.Data.Objects.ObjectQuery)querys).ToTraceString());

// 715. 49.9900 Long-Sleeve Logo Jersey, L
// 770. 782.9900 Road-650 Black, 52
// 825. 327.2150 HL Mountain Rear Wheel
// 880. 54.9900 Hydration Pack - 70 oz.
// 935. 40.4900 LL Mountain Pedal
// 990. 539.9900 Mountain-500 Black, 42
// SELECT
// [Extent1].[ProductID] AS [ProductID],
// [Extent1].[ListPrice] AS [ListPrice],
// [Extent1].[Name] AS [Name] 
// FROM [SalesLT].[Product] AS [Extent1]
// WHERE 0 = ([Extent1].[ProductID] % 55)

代码如下：

 public static Image BytesToImage(this byte[] bytes)

 {

        Image image = null;

        if (bytes != null)

        {

               using (MemoryStream  sm=new MemoryStream(bytes))

                {

                    image = Image.FromStream(sm);

                }

         }

            return image;

 }

问题在此：删除using, 在 Image 的生存期内，必须使流保持打开。详情见msdn

用.NET 自带的 ImageAnimator类来播放GIF图像

1. 注册动画事件
ImageAnimator.Animate(animatedImage, new EventHandler(this.OnFrameChanged));

2. 在OnFrameChanged事件中调用this.Invalidate();

3.  在OnPaint中绘当前帧
ImageAnimator.UpdateFrames(adimatedImage);
e.Graphics.DrawImage(adinatedImage, new Point(0,0));

sapi.dll:  %windir%\System32\Speech\Common

using SpeechLib;
SpVoice voice = new SpVoiceClass();
voice.Speak(text, SpeechVoiceSpeakFlags.SVSFDefault);

1. Solution：WebApp, WpfAff

2. WebApp add :  Silverlight-enabled WCF Service

[OperationContract]
        public IList<Customer> GetCustomers()
        {
            List<Customer> results = new List<Customer>();
            results.Add(new Customer {LastName="Brown",FisrtName="Pete" });
            results.Add(new Customer { LastName = "Stagner", FisrtName = "Joe" });
            results.Add(new Customer { LastName = "Liberty", FisrtName = "Jesse" });
            results.Add(new Customer { LastName = "Galloway", FisrtName = "Jon`" });
            return results;
        }

3. WpfApp:

       private void CallService_Click(object sender, RoutedEventArgs e)
        {
            var client = new Service.CustomerServiceClient();
            client.GetCustomersCompleted += (s, ev) =>
            {
                CustomerList.ItemsSource = ev.Result;
            };
            client.GetCustomersAsync();
        }

---------------------------------------------------

                   <StackPanel Orientation="Horizontal">
                        <TextBlock Text="{Binding LastName}" />
                        <TextBlock Text=", " />
                        <TextBlock  Text="{Binding FisrtName}"/>
                    </StackPanel>
                </DataTemplate>
