Hi, I got a scenario to create the anonymous list from the anonymous types, and i achieved that using public static List<T> MakeList<T>(T itemOftype) { List<T> newList = new List<T>(); return newList; } static void Main(string[] args) { //anonymos type var xx = new { ...
Greetings all, I am working on redesigning my personal Web site using VS 2008 and have chosen to use LINQ to create by data-access layer. Part of my site will be a little app to help manage my budget better. My first LINQ query does successfully execute and display in a GridView, but when I try to use a RowDataBound event to work with t...
This simple Linq query: from c in mycontext.Customers join o in mycontext.Orders on c.CustomerId equals o.CustomerId where o.Status == 1 select new {c, o} will result in List<{c:Customer, o:Order}> after calling ToList(). What's the easiest way of converting this anonymously typed list into a list of customers (List<Customer>)? E...
As the name of the anonymous type is compiler generated, so is it accessible through reflection? ...
Consider a scenario where a block of code is trying to pass an anonymous object to another method in C#. Here's an example: ThreadPool.QueueUserWorkItem(new WaitCallback(RpvService.GetRpvDailyResults), new { req = request, rpvDic = rpvDictionary } ); How can you receive the ano...
In Java, I know that it is possible to do something like this: public class Greeter { public void greetEventually() { final String greeting = "Hello!"; Job j = new Job() { public void run() { System.out.println(greeting); } }; j.schedule(); } } This would ...
Instinctively, I would say that this is impossible, as NHibernate needs to know some mapping information on how to persist a given type. Thus, I encountered some situations in which I could use such a feature. For instance, through a named query or something like so. On the other hand, using a named query would require me to make an addi...
I am trying to figure out how to get at an anonymous typed object's properties, when that anonymous type isn't created in the current function. Specifically, I am binding an ASP.NET ListView to LINQ resultset, then trying to process each item in the ItemDataBound event. Option Explicit On Option Strict On Class MyPageClass Privat...
I have a rather complicated query that I'd like to have return some particular types. Mostly concerning date / time calculations or string values, the Entity Framework seems to be spitting the dummy when I try anything further than a System.DateTime type: The specified type member 'Date' is not supported in LINQ to Entities. Onl...
I'm having a problem instantiating an anonymous type in my code. For some reason, TResponse response = default(TResponse); returns null, even though TResponse has a constructor for it. Am I being dumb?! Class: public class MyClass { public MyResponse GetResponse(MyRequest request) { return Service<MyRequest, MyResponse>.MakeR...
There doesn't seem to be any way as anonymous types derive from object. But I thought I'd ask since much of the time we use anonymous types in simple query expressions to extract subsets of data to be used in those anonymous types we create. It just seems to me they should be structs (value types) for greater memory efficiency vs. refere...
I'm creating an anonymous List<> here: var pip = new { MCP = "", Measure = "", Year = "", url1 = "", url2 = "", url3 = "" }; var PipList = (new[] { pip }).ToList(); The I loop through my code and load that list with items and bind it to my gridview: PipList.RemoveAt(0); gvReport.DataSource = PipList; gvReport.DataBind(); When I de...
I have a Dictionary(TKey, TValue) like Dictionary<int, ArrayList> Deduction_Employees = new Dictionary<int, ArrayList>(); and later I add to that array list an anonymous type like this var day_and_type = new { TheDay = myDay, EntranceOrExit = isEntranceDelay }; Deduction_Employees[Employee_ID].Add(day_and_type); Now h...
According to the MSDN: Because the Equals and GetHashCode methods on anonymous types are defined in terms of the Equals and GetHashcode of the properties, two instances of the same anonymous type are equal only if all their properties are equal. However, the following code demonstrates the compiler generated implementatio...
I have a WCF service method that expects an object and then retrieves its properties using reflection. On the client side I create an anonymous type object var obj = new {FirstName="John", LastName="Doe"} and pass it to the method. I'm getting an exception: Type '<>f__AnonymousType0`2[System.String,System.String]' cannot be serial...
Is there any way to declare a list object of anonymous type. I mean List<var> someVariable = new List<var>(); someVariable.Add( new{Name="Krishna", Phones = new[] {"555-555-5555", "666-666-6666"}} ); This is because I need to create a collection at runtime. Thanks in advance ...
I have a WinForms combobox to which I bind a list of anonymous objects (printer descriptions and locations). The goal here is a to select a default printer (which matches printer location). But within a foreach loop below, I am having trouble accessing the anonymous object's properties. I know of a work-around (I tried a private nes...
I am new in the functional side of C#, sorry if the question is lame. Given the following WRONG code: var jobSummaries = from job in jobs where ... select new { ID = job.ID, Description = job.Description, Fi...
I understood that anonymous types are marked private by the compiler and the properties are read-only. Is there a way to serialize them to xml (without deserialize) ? It works with JSON, how can I do it with XML? ...
Ok everyone, I must be missing something here. Every LINQ example I have seen for VB.NET anonymous types claims I can do something like this: Dim Info As EnumerableRowCollection = pDataSet.Tables(0).AsEnumerable Dim Infos = From a In Info _ Select New With {.Prop1 = a("P...
