Question

My requirements:

• I need to store a collection of objects inside a class,

• objects must be accessible by their key (which will be unique string), search/remove/replace must work like this

  MyClass somethingNew = new MyClass();
  // set someproperties on somethingNew    
  somethingNew.Id = "FooBar";    
  // theOtherObject already contains an object with the key "FooBar"    
  theOtherObject.Members[somethingNew.Id] = somethingNew;
  

• when new object is inserted no sort should happen,

• the property (collection) must be serializable to XML using DataContractSerializer.

So, what to choose for Members property?
I guess that List and SortedList are out of the question, so I am about to use generic

Dictionary<string, MyClass>.

Is this the right decision? Does it support serialization?

Answer 1

Dictionary<string, MyClass> is the correct option in this case.

And yes, it is Serializable.
