Datacontract Serialization Attributes
Schultz9999 - 1 year ago 210. DataContract XML serialization and XML attributes. Is it possible to deserialize this XML into an object marked with the DataContract attribute? Having read this post - DataContract XML serialization and XML attributes which is most interesting I have attempted to directly convert it to VB.NET, but it does not seem to give me the right results.
The problem isn't the map - protobuf-net would happily support Dictionary, to use the example from your links; it is the 'object'. Protobuf wants to know what it is deserializing. So again: what are the actual values? On 7 March 2016 at 09:14, rebulanyum wrote: Well it's just a collection with items of type KeyValuePair. And KeyValuePair is just a struct with 2 properties: Key and Value. So what should I do about it? And I think, on the contrary, Google.ProtocolBuffers supports map fields with version 3 and even with version 2.

That is expected. It knows that in the general case it doesn't know how to work with 'object', so it isn't happy to start trying, unless it has been specifically configured to treat it as a string-string map. But fundamentally, I would again simply suggest that anything based on this much implementation details rather than data details isn't a good choice for serialization.
The preference here (IMO) would be to create a DTO model specifically intended for serialization, that represents the data you want to serialize, rather than the active object model you happen to be using at the timel On 7 March 2016 at 14:32, rebulanyum wrote: Oh, I'm sorry for my bad understanding. The 'object' is sometimes string, sometimes Microsoft.Xrm.Sdk.EntityReference. It's not a single fixed type. But even strings are not serializing. — Reply to this email directly or view it on GitHub.

Apply the DataContractAttribute attribute to types (classes, structures, or enumerations) that are used in serialization and deserialization operations by the. If you send or receive messages by using the Windows Communication Foundation (WCF) infrastructure, you should also apply the DataContractAttribute to any classes that hold and manipulate data sent in messages.

For more information about data contracts, see. You must also apply the to any field, property, or event that holds values you want to serialize.
By applying the DataContractAttribute, you explicitly enable the to serialize and deserialize the data. A data contract is an abstract description of a set of fields with a name and data type for each field. The data contract exists outside of any single implementation to allow services on different platforms to interoperate. As long as the data passed between the services conforms to the same contract, all the services can process the data.
This processing is also known as a loosely coupled system. A data contract is also similar to an interface in that the contract specifies how data must be delivered so that it can be processed by an application. For example, the data contract may call for a data type named 'Person' that has two text fields, named 'FirstName' and 'LastName'.
To create a data contract, apply the DataContractAttribute to the class and apply the to any fields or properties that must be serialized. When serialized, the data conforms to the data contract that is implicitly built into the type. If you are exchanging data with other services, you must describe the data contract.
For the current version of the, an XML schema can be used to define data contracts. (Other forms of metadata/description could be used for the same purpose.) To create an XML schema from your application, use the with the /dconly command line option. When the input to the tool is an assembly, by default, the tool generates a set of XML schemas that define all the data contract types found in that assembly. Conversely, you can also use the Svcutil.exe tool to create Visual Basic or C# class definitions that conform to the requirements of XML schemas that use constructs that can be expressed by data contracts. In this case, the /dconly command line option is not required. If the input to the Svcutil.exe tool is an XML schema, by default, the tool creates a set of classes. If you examine those classes, you find that the DataContractAttribute has been applied.
