dynamicobject

问题 I have a requirement that several of my colleagues' configuration files should be displayed uniformly with the PropertyGrid control, which I have implemented with reference to the following post:https://www.codeproject.com/Articles/193462/Using-PropertyGrid-to-Display-and-Edit-Dynamic-Obj. My way is: define a ConfigObject object first, then deserialized json configuration file into ConfigObject object using JsonConvert.Convert(Newtonsoft.Json), and then assigned to the PropertyGrid

问题 I am trying to build a dynamic data container that allows (some of) the dynamically added properties to be bound to WinForm elements. So far, when I bind a regular object property the binding works fine. Sample: public class CompileTimePropertiesDataContainer { public string TestString = "Hello World"; } and then binding within the form works fine: var component = new CompileTimePropertiesDataContainer(); lblTestString.DataBinding.Add( "Text", component, "TestString", false,

问题 I know I can generate a class at runtime by executing $obj = (object)array('foo' => 'bar');+ this way I can use echo $obj->foo; //bar What if want to make $obj inherits from an existing class? What I wanna achive: I'm forking paris project on github (https://github.com/balanza/paris). It's an active record class. I wonder I need to declare a class for every object, even if it's empty: class User extends Model{} I guess I might use dynamic object to avoid this boring stuff. 回答1: You could

问题 If I have a dynamic object, or anonymous object for that matter, whose structure exactly matches that of a strongly typed object, is there a .NET method to build a typed object from the dynamic object? I know I can use a LINQ dynamicList.Select(dynamic => new Typed { .... } type thing, or I can use Automapper, but I'm wondering if there is not something specially built for this? 回答1: You could serialize to an intermediate format, just to deserialize it right thereafter. It's not the most

问题 I have a simple set of JSON that needs to be reformatted since all of the key value pairs are not always output. { "result": [ { "category": "Negative Notification", "event": "open", "result": 2 }, { "category": "Referral", "event": "bounce", "result": 1 }, { "category": "Negative Notification", "event": "delivered", "result": 34 }, { "category": "Negative Notification", "event": "processed", "result": 34 }, { "category": "Positive Notification", "event": "open", "result": 42 }, { "category":

问题 i have a Stored Procedure that returns multiple datatables with dynamic types according to the input and I cannot modify or split it. I actually retrieve the data in this way: var massiveModel = new DynamicModel(dbConn.ConnectionString); var connection = new SqlConnection(@"Data Source=127.0.0.1;Initial Catalog=TEST;User ID=as;Password=;Application Name=BRUCE_WAYNE"); connection.Open(); var massiveConnection = connection; var tmp = massiveModel.Query("exec MY_SP 4412 '20131016' ",

问题 I have a class that derives from DynamicObject class. On calling JsonConvert.SertializeObject, none of the dynamic properties are serialized. Class is defined as, public class Component : DynamicObject { // The inner dictionary. public Dictionary<string, object> dictionary = new Dictionary<string, object>(); [JsonProperty(PropertyName = "id")] public string Id { get; set; } // If you try to get a value of a property // not defined in the class, this method is called. public override bool

问题 I'm trying to create and populate a dynamic object from a dataset that is only known at run time. In the code below, I create my IEnumerable results from my dataset with some known fields (ID, Primary Data, DisplayOrder, IsActive) and one user-define field (Phone Number) which I won't know at design time, and therefore must be built dynamically. The code below works, but only because I've hard-coded the dynamic field Phone Number. How do I build the Lambda expression dynamically to handle

问题 I'm successfully using the JavaScriptSerializer in MVC3 to de-serialize a json string in to a dynamic object. What I can't figure out is how to cast it to something I can enumerate over. The foreach line of code below is my latest attemt but it errors with: "Cannot implicitly convert type 'System.Dynamic.DynamicObject' to 'System.Collections.IEnumerable'. How can I convert or cast so that I can iterate through the dictionary? public dynamic GetEntities(string entityName, string entityField) {

问题 Is it possible to determine what type a dynamic member access expects? I've tried dynamic foo = new MyDynamicObject(); int x = foo.IntValue; int y = (int)foo.IntValue; And in the TryGetMember intercept GetMemberBinder.ReturnType is object either way. I also implemented TryConvert wondering if it might get invoked to do the conversion, but it never is hit. Is there some other override I'm missing that lets me determine what Type the caller wants so that I can do the appropriate conversion? 回答1
