I am trying to send serialized,compressed data over a tcp connection using protobuf-net
and
GzipStream
The deserializing or reading from the zipstream just blocks and does not complete.
To test it I opted to try using a simpler FileStream
to see that the data was actually being compressed and written, which it was.
However the line Console.writeLine(inPerson1.name)
throws a Object reference not set exception
since it seems to be not reading any data from the zipstream.
Any thoughts on why, or what I am doing wrong?
Code:
public void TestZipToFile(){
var person1 = new Person { id = 1, name = "Pete" };
var person2 = new Person { id = 2, name = "Sarah" };
using (var file = File.Create("people.bin"))
{
GZipStream zs = new GZipStream(file, CompressionMode.Compress);
Serializer.SerializeWithLengthPrefix<Person>(zs, person1, PrefixStyle.Fixed32);//.Serialize(file, foo);
Serializer.SerializeWithLengthPrefix<Person>(zs, person2, PrefixStyle.Fixed32);//.Serialize(file, foo);
}
Person inPerson1 = null;
Person inPerson2 = null;
using (var file = File.OpenRead("people.bin"))
{
GZipStream ozs = new GZipStream(file, CompressionMode.Decompress);
inPerson1 = Serializer.DeserializeWithLengthPrefix<Person>(ozs,PrefixStyle.Fixed32);//.Deserialize<Foo>(file);
inPerson2 = Serializer.DeserializeWithLengthPrefix<Person>(ozs, PrefixStyle.Fixed32);//.Deserialize<Foo>(file);
}
Console.WriteLine(inPerson1.name);
Console.WriteLine(inPerson2.name);
}
[ProtoContract]
public class Person
{
[ProtoMember(1)
public int id;
[ProtoMember(2)]
public string name;
}
You're never closing the output GZipStream
, so I suspect it ends up never writing anything to the underlying stream. You should have a using
statement for each GZipStream
as well as the FileStream
.
