C＃序列化通用列表 <customObject> 提交

Question

我有一個類，其中包含有關圖片的信息，如filepath，hashvalue，bytes。 在另一個類中，我得到了一個通用列表，其中我放置了包含圖片信息的類中的對象。

那個類看起來像這樣：

[Serializable()]
    class PicInfo : ISerializable
    {
        public string fileName { get; set; }
        public string completeFileName { get; set; }
        public string filePath { get; set; }
        public byte[] hashValue { get; set; }

        public PicInfo()
        { }

        public PicInfo(SerializationInfo info, StreamingContext ctxt)
        {
            this.fileName = (string)info.GetValue("fileName", typeof(string));
            this.completeFileName = (string)info.GetValue("completeFileName", typeof(string));
            this.filePath = (string)info.GetValue("filePath", typeof(string));
            this.hashValue = (byte[])info.GetValue("hashValue", typeof(byte[]));
        }

        public void GetObjectData(SerializationInfo info, StreamingContext ctxt)
        {
            info.AddValue("fileName", this.fileName);
            info.AddValue("completeFileName", this.completeFileName);
            info.AddValue("filePath", this.filePath);
            info.AddValue("hashValue", this.hashValue);
        }
    }

我的列表只是list<picinfo> pi = new list<picinfo>(); 序列化這個列表最簡單的方法是什么？

如果你想使用BinaryFormatter （我真的不建議），你可以使用：

[Serializable]
class PicInfo
{
    public string fileName { get; set; }
    public string completeFileName { get; set; }
    public string filePath { get; set; }
    public byte[] hashValue { get; set; }

    public PicInfo()  { }
}
static class Program
{
    static void Main()
    {
        List<PicInfo> pi = new List<PicInfo>();
        pi.Add(new PicInfo {fileName = "foo.bar", hashValue = new byte[] {1, 2, 3}});

        var ser = new BinaryFormatter();
        using (var ms = new MemoryStream())
        {
            ser.Serialize(ms, pi);
            var bytes = ms.ToArray();
        }
    }
}

如果你想使用XmlSerializer （可能更喜歡IMO），但需要byte[] ，那么：

public class PicInfo
{
    public string fileName { get; set; }
    public string completeFileName { get; set; }
    public string filePath { get; set; }
    public byte[] hashValue { get; set; }

    public PicInfo()  { }
}
static class Program
{
    static void Main()
    {
        List<PicInfo> pi = new List<PicInfo>();
        pi.Add(new PicInfo {fileName = "foo.bar", hashValue = new byte[] {1, 2, 3}});

        var ser = new XmlSerializer(typeof(List<PicInfo>));
        using (var ms = new MemoryStream())
        {
            ser.Serialize(ms, pi);
            var bytes = ms.ToArray();
        }
    }
}

就個人而言，我使用protobuf-net：

[ProtoContract]
public class PicInfo
{
    [ProtoMember(1)]public string fileName { get; set; }
    [ProtoMember(2)]public string completeFileName { get; set; }
    [ProtoMember(3)]public string filePath { get; set; }
    [ProtoMember(4)]public byte[] hashValue { get; set; }

    public PicInfo()  { }
}
static class Program
{
    static void Main()
    {
        List<PicInfo> pi = new List<PicInfo>();
        pi.Add(new PicInfo {fileName = "foo.bar", hashValue = new byte[] {1, 2, 3}});

        using (var ms = new MemoryStream())
        {
            Serializer.Serialize(ms, pi);
            var bytes = ms.ToArray();
        }
    }
}
