  • Skapa Microsoft Tags på din hemsida

    Något som är riktigt häftigt är Microsoft Tags. Det är små taggar i form av bilder som man kan använda för att t.ex. göra det enkelt att surfa till en viss URL genom att bara peka mobilkameran mot den. Det kan användas i reklamsyfte, man kan ha det på sitt visitkort för att länka till bloggen eller vad man nu önskar.

  • Framtiden för ASP.NET MVC

    Jag har tidigare nämnt att det som finns i ASP.NET MVC 2 Preview 2 (och Preview 1 förstås) är något som är långt ifrån färdigt, och mycket väl kan fungera helt annorlunda när det väl är släppt. Ser man på ASP.NET MVC 1 så var det enorm skillnad på de första preview-versionerna jämfört med den färdiga produkten.

  • Skapa objekt med data dynamiskt med ExpandoObject

    När man arbetar med dynamic i .NET 4.0 så tar man ett befintligt objekt och säger att man vill använda vissa metoder eller egenskaper som finns för det objektet. Det laddas anropas sedan under runtime. Om objektet inte har de metoder som finns så får man under runtime ett fel om det, trots att allt kompilerade utan problem.

    Så hur gör vi nu om vi vill skapa ett dynamiskt objekt och berätta för det vilka egenskaper och värden som finns samt till dela dem värden för att sedan anropa dem?

    I .NET 4.0 under System.Dynamic så finns det ett objekt för detta, kallat ExpandoObject. Det är ett helt tomt objekt utan några egenskaper eller metoder som helst förutom de vanliga Equals(), GetHashCode(), GetType() och ToString(). Det implementerar dock ett antal interfaces, vilka används internt för att hålla reda på de metoder vi lägger på det dynamiska objektet: IDynamicMetaObjectProvider, IDictionary<string, Object>, ICollection<KeyValuePair<string, Object>>, IEnumerable<KeyValuePair<string, Object>> och IEnumerable.

    När vi använder ExpandoObject så kan vi skapa instansen som vanligt:

    ExpandoObject o = new ExpandoObject(); 

    Det här gör dock att vi star där med en instans av ett object som inte kan göra något förutom att visa att det är ett ExpandoObject, ingen höjdare alltså.

    Vi kan däremot skapa en dynamisk instans av detta objekt, och då lägga på några metoder.

    dynamic magic = new ExpandoObject();
     
    magic.IntX = 10;
    magic.IntY = 20;
    magic.Name = "Nisse";
    magic.SayHello = new Action<string>(x => Console.WriteLine("Hello, " + x + "!"));
    magic.Multiply = new Func<int, int, int>((x, y) => x * y);

    Här har vi skapat en dynamisk instans av ett ExpandoObject, och säger att vi har ett antal metoder och egenskaper som ska finnas på det objektet.

    Om det här hade varit en instans av ett vanligt objekt så hade vi fått ett runtime-fel som sager att metoderna inte finns för objektet. Det naturliga vore om detsamma gäller för detta objekt, så vi lägger till de här raderna under:

    Console.WriteLine("X: {0}", magic.IntX);
    Console.WriteLine("Y: {0}", magic.IntY);
    Console.WriteLine("Name: {0}", magic.Name);
    Console.WriteLine("Multiply(X, Y): {0}", magic.Multiply(magic.IntX, magic.IntY));
    magic.SayHello(magic.Name);

    När vi nu startar igång programmet så ser vi att vi inte alls fick något fel, utan istället det här:

    1 - Console

    Vi har alltså skapat upp ett dynamiskt objekt och tilldelat det metoder och egenskaper, på precis samma sätt som vi hade gjort med ett dynamiskt språk som JavaScript eller IronRuby, trots att det är ett statiskt språk vi arbetar med!

    Så hur går det till? Som jag nämnde tidigare så implementerar ExpandoObject ett antal interfaces som används för collections. När vi tilldelar vårt objekt egenskaper med dess värden så lagras dessa i collections internt i objektet, och plockas sedan fram när vi anropar dem.

    Om vi debuggar så ser vi att vi får upp detta:

    2 - Debug Dynamic View

    I Visual Studio 2010 så finns det en ny visualizer som används för att visa vad som finns i dynamiska vyer som denna. Vi kan här se att det har skapats olika metoder för vårt objekt med antingen datan vi har skickat in, eller de delegater som används (Action<string> och Func<int, int, int>).

    Om vi går ännu djupare så kan vi se att det i vårt objekt finns en Dictionary<string, object> som håller reda på våra objekt:

    3 - Dictionary

    Vi kan enkelt se alla nycklar:

    4 - Keys

    Och värden:

    5 - Values

    Om vi analyserar IL-koden så kan vi se att Action<> och Func<> har skrivits om till vanliga void.

    SayHello:

    .method private hidebysig static void <Main>b__12(string x) cil managed
    {
        .custom instance void [mscorlib]System.Runtime.CompilerServices.CompilerGeneratedAttribute::.ctor()
        .maxstack 8
        L_0000: ldstr "Hello, "
        L_0005: ldarg.0 
        L_0006: ldstr "!"
        L_000b: call string [mscorlib]System.String::Concat(string, string, string)
        L_0010: call void [mscorlib]System.Console::WriteLine(string)
        L_0015: nop 
        L_0016: ret 
    }
     
    .field private static class [mscorlib]System.Action`1<string> CS$<>9__CachedAnonymousMethodDelegate14
    {
        .custom instance void [mscorlib]System.Runtime.CompilerServices.CompilerGeneratedAttribute::.ctor()
    }

    Multiply:

    .method private hidebysig static int32 <Main>b__13(int32 x, int32 y) cil managed
    {
        .custom instance void [mscorlib]System.Runtime.CompilerServices.CompilerGeneratedAttribute::.ctor()
        .maxstack 2
        .locals init (
            [0] int32 CS$1$0000)
        L_0000: ldarg.0 
        L_0001: ldarg.1 
        L_0002: mul 
        L_0003: stloc.0 
        L_0004: br.s L_0006
        L_0006: ldloc.0 
        L_0007: ret 
    }
     
    .field private static class [mscorlib]System.Func`3<int32, int32, int32> CS$<>9__CachedAnonymousMethodDelegate15
    {
        .custom instance void [mscorlib]System.Runtime.CompilerServices.CompilerGeneratedAttribute::.ctor()
    }

    Det är inga konstigheter här, utan vid kompilering så sker detta alltid automatiskt.

    Därememot så är Main-metoden mer intressant.

    .method private hidebysig static void Main(string[] args) cil managed
    {
        .entrypoint
        .maxstack 15

    För att göra en lång historia kort... Det som sker är att det först skapas upp en instans av ExpandoObject, vilket ger ett object. Sedan används ett antal CallSites för att skapa upp en dynamisk call site som har hand om alla dynamiska handlingar som sker mot objektet.

    När objektet binds så returneras ett expression tree med data för objektet, vilket sedan används för att arbeta med de metoder och den data som vi tidigare har skapat.

    Då objekten skapas upp under runtime så kan vi även använda dem runt om i applikationen, vilket gör att vi kan göra t.ex. så här:

    static dynamic GetExpendo()
    {
        dynamic magic = new ExpandoObject();
     
        magic.IntX = 10;
        magic.IntY = 20;
        magic.Name = "Nisse";
        magic.SayHello = new Action<string>(x => Console.WriteLine("Hello, " + x + "!"));
        magic.Multiply = new Func<int, int, int>((x, y) => x * y);
     
        return magic;
    }

    Vi kan sedan skapa upp objektet genom:

    dynamic magic = GetExpendo();

    Det här fungerar lika bra som innan. Med andra ord så behandlas dynamiska ExpandoObject-instanser på samma sätt som vanliga statiska instanser.

  • Areor i ASP.NET MVC 2

    När man utvecklar större webbplatser så brukar det underlätta om man kan dela upp dessa i olika areor där varje area kan handla om ett eget ämne. I ASP.NET MVC så har vi tidigare fått skapa upp en större mängd controllers med tillhörande vyer, men med ASP.NET MVC 2 så finns möjligheten att skapa dessa areor enklare.
