问题 I was troubleshooting a (de)serialization issue with the following class using Json.Net: public class CoinsWithdrawn { public DateTimeOffset WithdrawlDate { get; private set; } public Dictionary<CoinType, int> NumberOfCoinsByType { get; private set; } public CoinsWithdrawn(DateTimeOffset withdrawDate, Dictionary<CoinType, int> numberOfCoinsByType) { WithdrawlDate = withdrawDate; NumberOfCoinsByType = numberOfCoinsByType; } } The problem is that the constructor argument "withdrawDate" is named

问题 I am implementing a user control that has a method that takes an Action delegate as a parm. Attempting to store the delegate in Control State yields a serialization error. Is it even possible to serialize a delegate into Control State? BP 回答1: Not easily - and it could open the door for potential problems. It is theoretically possible to use reflection to determine which method of an object the delegate is invoking, and write a custom serialization process for it. Upon deserialization you

问题 I have a simple JSON statement which type is very per need. like this { actor:{name:"kumar",mbox:"kumar@gmail.com"} verb :"completed" } or { actor:{name:["kumar","manish"],mbox:["kumar@gmail.com","manish@gmail.com"]} verb :{ "id" : "http://adlnet.gov/expapi/verbs/completed", "display" : { "en-US" : "completed" } } I am using using POJO class to map this json string and pojo class code is given bleow @JsonProperty("actor") Actor actor; @JsonProperty("verb") Verb objVerb; @JsonProperty("verb")

问题 In Java it is strongly recommended that all serializable classes explicitly declare serialVersionUID since the default serialVersionUID computation is highly sensitive to class details and compiler implementation is unreliable. What's so special about serialization in C#? 回答1: In .Net Serialization is less cranky than in Java. By default it supports new fields just defaulting them, and it just ignore any data it doesn't expect. You can still implement the same kind of version control by

问题 I have trouble deserializing the result from my WCF webservice. The method returns a List<RecipeEntity> , which is serialized to XML as shown below. When I try to deserialize I just get an exception, shown below. It seems I cannot deserialize <ArrayOfRecipe> to List<RecipeEntity> . Note that RecipeEntity is mapped by contract name to Recipe . After searching I see many propose XmlArray and XmlElement attributes, but as far as I can tell they do not apply here on the GetRecipes() method. I
