The key to this question is aiding unit-testing. If I have a busy __init__ (i.e. __init__ that does complex initialization), I cannot simply instantiate an object of a class, but I need to mock/stu...

I have used auto properties a lot but I have gone more and more away from that setting up classes with readonly backing fields initialized in the constructor. I remove all setters and only add the ...

Why is it possible to use an object initializer to set a private set auto property, when the initializer is called from within the class which owns the auto property? I have included two class as a...

Im trying to use DynamicObject in c#, and I needed an array of dynamic: var d = new dynamic[]; which works fine. EDIT : See ExpandoObject below. But I also like to fill that array with some d...

say that I have an class that has a property that is a dictionary<string,bool>, using a object initializer I can use this syntax (which I think looks pretty clean): new MyClass() { Table = ...

C# does not allow an instance field initializer to reference another field. For instance this code is not valid : class A { string s1 = ""; string s2 = s1; } because "s2" references "s1". But...

This code compiles successfully, but I think it should fail to compile. Also, when you run it you get a NullReferenceException. The missing code is the "new Bar" in the initialization of the Bar pr...

Can I somehow get a reference to the instance I am creating using object initialiser var x = new TestClass { Id = 1, SomeProperty = SomeMethod(this) } "this" should point to the new TestClas...

I was too excited when object initializer appeared in C#. MyClass a = new MyClass(); a.Field1 = Value1; a.Field2 = Value2; can be rewritten shorter: MyClass a = new MyClass { Field1 = Value1, ...

At face value, it would seem that object initializers present a problem for .net 4.0 "code contracts", where normally the invariant should be established by the time the object constructor is finis...

With an object initializer, is it possible to optionally include setting of property? For example: Request request = new Request { Property1 = something1, if(something) Property2 = someting2, ...

I have a simple question about creating multiple initialisers within an objective-c class. Basically I have a class that represents a single row in my database (users). I currently have an initiali...

I like the C# 3 initializer syntax and use it a lot, but today while looking in Reflector, the following came up: var binding = new WSHttpBinding { ReaderQuotas = { MaxArrayLength = 100000 }, Ma...

In C#, you can do something like this: SomeClass someClass = new SomeClass () { SomeProperty = someValue }; What is this syntax called?

When i initialize an object using the new object initializers in C# I cannot use one of the properties within the class to perform a further action and I do not know why. My example code: Person ...

Does the order in which I set properties using the object initializer syntax get executed in the exact same order? For instance if I do this: var s = new Person { FirstName = "Micah", LastName =...
