DataContractJsonSerializer and maxItemsInObjectGraph

由 天大地大妈咪最大 提交于 2019-12-11 11:34:43
问题 How can I set the maxItemsInObjectGraph for the DataContractJsonSerializer? I get an error saying "Maximum number of items that can be serialized or deserialized in an object graph is '65536'. Change the object graph or increase the MaxItemsInObjectGraph quota." Where does the number 65536 come from. The documentation for DataContractJsonSerializer says the default is Int32.MaxValue. I tried to set it in the behavior configuration: <endpointBehaviors> <behavior name="WebBehavior"> <webHttp />

Using DataContractJsonSerializer to create a Non XML Json file

问题 I want to use the DataContractJsonSerializer to serialize to file in JsonFormat. The problem is that the WriteObject method only has 3 options XmlWriter, XmlDictionaryWriter and Stream. To get what I want I used the following code: var js = new DataContractJsonSerializer(typeof(T), _knownTypes); using (var ms = new MemoryStream()) { js.WriteObject(ms, item); ms.Position = 0; using (var sr = new StreamReader(ms)) { using (var writer = new StreamWriter(path, false)) { string jsonData = sr

How do I get DataContractJsonSerializer to use concrete type in type hint when serializing generic class from interface

问题 I have a set of classes as follows: a Command, which Executes and stores a Result; a Response, which is created as in order to return the Result in a serialized form (plus extra metadata which I've left out). The Response.Result must be of type object, as it is used for a bunch of different commands, each of which can have a Result of any type at all. The Command is generic, and I'd like it to accept an interface rather than concrete type, but when I do, the serialized response contains the

问题 When I try and deserialize a JSON string which contains a £ symbol I get the exception. There was an error deserializing the object of type RD.Details. '�19.95 Per Person' contains invalid UTF8 bytes. The string which I log is as below: { "Promotions":[ { "Name":"Traditional Afternoon Tea £19.95 Per Person", "PromotionId":20175, "Quantity":2 } ] } This is how I am deserializing: var responseJsonSerializer = new DataContractJsonSerializer(typeof(TR)); Stream serializedStream; string

Deserialization of JSON object by using DataContractJsonSerializer in C#

问题 I'm sure this question has been asked over and over again, but for some reason, I still can't manage to get this to work. I want to deserialize a JSON object that contains a single member; a string array: [{"idTercero":"cod_Tercero"}] This is the class that I'm trying to deserialize into: [DataContract] public class rptaOk { [DataMember] public string idTercero { get; set; } public rptaOk() { } public rptaOk(string idTercero) { this.idTercero = idTercero; } } This is the method that I try to

Can DataContractJsonSerializer handle cyclic references?

由 夙愿已清 提交于 2019-12-10 10:47:59
问题 Are there any serialization/deserialization scenarios that DataContractSerializer can handle, while DataContractJsonSerializer can't ? In particular, I am thinking of circular references: this MSDN page explains how circular references can be managed by DataContractSerializer via the use of IsReference = true in the DataContractAttribute constructor. On the other hand, the DataContractAttribute.IsReference documentation does not explicitly state that its applicability is limited to
