是否可以将protobuf序列化的内容直接写入SharpZipLib流?当我尝试执行此操作时,看起来所提供的流中未填充protobuf中的数据。稍后,我需要从提供的Zip流中获取反序列化的实体。
我的代码如下所示:
private byte[] ZipContent(T2 content)
{
const short COMPRESSION_LEVEL = 4; // 0-9
const string ENTRY_NAME = "DefaultEntryName";
byte[] result = null;
if (content == null)
return result;
IStreamSerializerProto<T2> serializer = this.GetSerializer(content.GetType());
using (MemoryStream outputStream = new MemoryStream())
{
using (ZipOutputStream zipOutputStream = new ZipOutputStream(outputStream))
{
zipOutputStream.SetLevel(COMPRESSION_LEVEL);
ZipEntry entry = new ZipEntry(ENTRY_NAME);
entry.DateTime = DateTime.Now;
zipOutputStream.PutNextEntry(entry);
serializer.Serialize(zipOutputStream, content);
}
result = outputStream.ToArray();
}
return result;
}
private class ProtobufStreamSerializer<T3> : IStreamSerializerProto<T3>
{
public ProtobufStreamSerializer()
{
ProtoBuf.Serializer.PrepareSerializer<T3>();
}
public void Serialize(Stream outputStream, T3 content)
{
Serializer.Serialize(outputStream, content);
}
public T3 Deserialize(Stream inputStream)
{
T3 deserializedObj;
using (inputStream)
{
deserializedObj = ProtoBuf.Serializer.Deserialize<T3>(inputStream);
}
return deserializedObj;
}
}
我要序列化的类的示例:
[Serializable]
[ProtoContract]
public class Model
{
[XmlElement("ModelCode")]
[ProtoMember(1)]
public int ModelCode { get; set; }
...
}
最佳答案
我相信这是问题所在(在问题的原始代码中):
public void Serialize(Stream outputStream, T3 content)
{
using (var stream = new MemoryStream())
{
Serializer.Serialize(stream, content);
}
}
您完全忽略了
outputStream
,而是仅将数据写入新的MemoryStream
,然后将其忽略。我怀疑您只想要:
public void Serialize(Stream outputStream, T3 content)
{
Serializer.Serialize(outputStream, content);
}
我还建议从您的
using
方法中删除Deserialize
语句:我希望调用者在完成输入流后负责处理输入流。您的方法可以简化为:public T3 Deserialize(Stream inputStream)
{
return ProtoBuf.Serializer.Deserialize<T3>(inputStream);
}
