问题 I have the following XML generated using a function FreezeAllAccountsForUser. I need to serialize only the following two columns for this function. How can I restrict the serialization to two columns? BankAccountID Status Note: The key point is that the scope of making this restriction should be only within the function FreezeAllAccountsForUser; not global .

问题 Can someone give me good explanation why this has to fail? const int bufferSize = 2 * 1024, testValue = 123456; var buffer = new byte[bufferSize]; var serializer = new DataContractSerializer(typeof(int)); //Serialize value using (var memStream = new MemoryStream(buffer)) using (XmlDictionaryWriter writer = XmlDictionaryWriter.CreateBinaryWriter(memStream)) serializer.WriteObject(writer, testValue); //Deserialize value using (var memStream = new MemoryStream(buffer)) using (XmlDictionaryReader

问题 I'm trying to map GeoJSON to DataContracts for use in some WCF-services at work. GeoJSON has a field called "type" and the DataContracts-serialization depends on the field " _ _type" to support de/serializing to the correct subtypes. My DataContracts are all named after the GeoJSON spec and I've set the Namespace of the DataContracts to "", so basically I have managed to implement GeoJSON <==> DataContracts if only i could tell the (de)serializer to use the field "type" instead of the field "

问题 I create xsd's based upon client's documentation and all of the xsd's have attributes. I have been using xsd.exe to generate the classes from the xsd's, but I read that attributes aren't supported for the DataContractSerializer. Why not? Does this mean that I can only have an soap+xml file with just elements? This is not possible because I don't create the requests. Is there a way to specify to svcutil to recognize attributes? 回答1: DataContractSerializer was created with a "code-first"

问题 I have some code something like this: [DataContract] class Foo { [OnSerializing] private void BeforeSerialize(StreamingContext ctx) { ((MtType)ctx.Context).DoStuff() } ... } var reader = new XmlTextReader(filename); var serializer = new DataContractSerializer(typeof(Type)); Type type = (Type)serializer.ReadObject(reader); and I need to provide the StreamingContext structure. I have found several references that this can be done for NetDataContractSerializer but none for DataContractSerializer
