NetworkComms V3 之自定义对象

浏览数：203 / 时间：2015年06月09日

能够发送自定义对象，并且在发送的时候对发送的对象进行加密，压缩是networkComms v3框架的一个重要特性。

具体可以参考源码中 ExampleConsole 工程文件

使用NetworkComms V3 框架发送自定义对象的语法如下：

CustomObject myCustomObject = new CustomObject("ben", 25);
NetworkComms.SendObject("Message", "127.0.0.1", 10000, myCustomObject);

如果您使用的是protobuf.net序列化器，那么自定义对象的语法如下：


[ProtoContract]
private class CustomObject
{
    [ProtoMember(1)]
    public int Age { get; private set; }
 
    [ProtoMember(2)]
    public string Name { get; private set; }
 
    /// <summary>
    /// Parameterless constructor required for protobuf
    /// </summary>
    protected CustomObject() { }
 
    public CustomObject(string name, int age)
    {
        this.Name = name;
        this.Age = age;
    }
}

对于一些不支持序列化的类，比如image 类的序列化，要进行一些转换，如下：

[ProtoContract]
public class ImageWrapper
{
    /// <summary>
    /// Private store of the image data as a byte[]
    /// This will be populated automatically when the object is serialised
    /// </summary>
    [ProtoMember(1)]
    private byte[] _imageData;
 
    /// <summary>
    /// The image name
    /// </summary>
    [ProtoMember(2)]
    public string ImageName { get; set; }
 
    /// <summary>
    /// The public accessor for the image. This will be populated
    /// automatically when the object is deserialised.
    /// </summary>
    public Image Image { get; set; }
 
    /// <summary>
    /// Private parameterless constructor required for deserialisation
    /// </summary>
    private ImageWrapper() { }
 
    /// <summary>
    /// Create a new ImageWrapper
    /// </summary>
    /// <param name="imageName"></param>
    /// <param name="image"></param>
    public ImageWrapper(string imageName, Image image)
    {
        this.ImageName = imageName;
        this.Image = image;
    }
 
    /// <summary>
    /// Before serialising this object convert the image into binary data
    /// </summary>
    [ProtoBeforeSerialization]
    private void Serialize()
    {
        if (Image != null)
        {
            //We need to decide how to convert our image to its raw binary form here
            using (MemoryStream inputStream = new MemoryStream())
            {
                //For basic image types the features are part of the .net framework
                Image.Save(inputStream, Image.RawFormat);
 
                //If we wanted to include additional data processing here
                //such as compression, encryption etc we can still use the features provided by NetworkComms.Net
                //e.g. see DPSManager.GetDataProcessor<LZMACompressor>()
 
                //Store the binary image data as bytes[]
                _imageData = inputStream.ToArray();
            }
        }
    }
 
    /// <summary>
    /// When deserialising the object convert the binary data back into an image object
    /// </summary>
    [ProtoAfterDeserialization]
    private void Deserialize()
    {
        MemoryStream ms = new MemoryStream(_imageData);
 
        //If we added custom data processes we have the perform the reverse operations here before 
        //trying to recreate the image object
        //e.g. DPSManager.GetDataProcessor<LZMACompressor>()
 
        Image = Image.FromStream(ms);
        _imageData = null;
    }
}
