protobuf-net

问题 Why is not possible to Deserialize without providing output type? Typically if two endpoints are communicating, both ends are sharing the same types. In my case i'm using exactly the same library on the client and on the server application. On startup i register all my types both on client and server like this: var metaType = RuntimeTypeModel.Default.Add( type, false ); foreach( var prop in type.GetProperties() ) metaType.Add( i++, prop.Name ); and so i expect protobuf to try to understand

问题 I serialized data using protobuf-net, and am able to deser the same in C#. putting a C# dummy w# var file = File.Create("animal.bin"); //Creating Msg - Fill the Data animal.id = "1"; animal.Name = "Rat"; animal.host = "Cheetha"; ProtoBuf.Serializer.SerializeWithLengthPrefix(file, animal, PrefixStyle.Base128, 1); animal.id = "2"; animal.Name = "Cat"; animal.host = "Cheetha"; ProtoBuf.Serializer.SerializeWithLengthPrefix(file, animal, PrefixStyle.Base128, 1); .... animal.id = "4"; animal.name =

问题 Using types with hidden fields leads to an "Unable to determine member" Exception (V2 via RuntimeTypeModel without any attributes). Removing the Length check in this line in MetaType.cs solves the problem for this special use case. if(members != null && members.Length == 1) mi = members[0]; But I fear there is a reason for the length check, so simply removing it might not be an adequate solution. Using members[0] works in this case, because the hidden base class members go at the end of the

问题 Got POCO with 100+ fields (using DataMember(Order=X) attribute to mark them for ProtoBuf.Net serialisation). We need to do some post processing of the file where one field's value needs to calced (which we can only do once we have read through it once) be updated and saved down again. Atm we are resaving into new file and this obviously has some IO/file overhead. Is there any way I can update existing file where only Field "X"'s value needs to be updated and saved down. Hopefully this should

问题 I saw a question related to this on the full framework here. Since it seems to have stayed unresolved for quite a while and this is for the compact framework, I though it would be better to create a new question for it. I want to deserialize types for which I am loading assemblies dynamically (with Assembly.LoadFrom) and I am getting a "Unable to identify known-type for ProtoIncludeAttribute" error. In the related question I mentioned, it was hinted that hooking AppDomain.AssemblyResolve

问题 Context I'm have a file with the following structure: [ProtoContract] public class Data { [ProtoMember(1)] public string Header { get; set; } [ProtoMember(2)] public byte[] Body { get; set; } } The code that reads / writes the data to a file is running on a asp.net mvc webapi context. I'm trying to keep every blocking IO async to minimize blocking and achieve the best scalability. Reading and writing from files does support ReadAsync, WriteAsync and CopyToAsync. The body can be reasonably

问题 I am trying to construct a serialisation system for our application that must be able to handle inheritance. To further complicate matters the application is extensible so types might are very unlikely to be known at compile time. I have read through a previous stackoverflow question that was answered and that helped me get a long way to my goal but I have hit a stumbling block that is probably more of a lack of understanding than any real issue! So this is the code that I have currently...

问题 I have written this protobuf message in c# C# client: public AddressBook InitializeAdressBook() { Person newContact = new Person(); AddressBook addressBookBuilder = new AddressBook(); Person john = new Person(); john.id=1234; john.name="John Doe"; john.email="jdoe@example.com"; Person.PhoneNumber nr = new Person.PhoneNumber(); nr.number="5554321"; john.phone.Add(nr); addressBookBuilder.person.Add(john); TextBox.Text += ("Client: Initialisiert? " + addressBookBuilder.ToString()) + "\t" + "\n";

问题 I have a list of objects of various data types (DateTime, int, decimal, string). List<object> myObjects = new List<object>(); myObjects.Add(3); myObjects.Add(3.9m); myObjects.Add(DateTime.Now); myObjects.Add("HELLO"); I was able to serialize this list using protobuf-net, but deserialization always throws the exception: "Additional information: Type is not expected, and no contract can be inferred: System.Object". using (var ms = new MemoryStream()) { Serializer.Serialize(ms, list2); var bytes

问题 I am using protobuf-net for my protocol buffering. I have a dll I am loading dynamically. I can create an instance of a data class contained within the dll, and I can use and modify the created data object. However, When I attempt to serialize/deserialize the data object I get the following crash: {"Unable to identify known-type for ProtoIncludeAttribute: MyDataDLL.MyDataClass, MyDataDLL, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null"} and sometimes a crash saying that MyDataClass is
