If you provide your own get/set then you need to provide your own storage for the variable. private float _inverseMass; public float inverseMass { get { return _inverseMass; } set { _inverseMass = value; onMassChanged(); } }
It´s not supported for auto implemented properties. You have to use a backing field and set the NonSerializedAttribute on it. public class ClassWithNonSerializedProperty { [NonSerialized] private object _data; // Backing field of Property Data that is not serialized public object Data{ get { return _data; } set { _data = value; } } }
At first I thought it was a beta version bug, but today I saw that this type of errors occur on the XCode 6 GM Seed also, though I’m yet to discover in which particular cases. Anyway, the fix is to add a synthesize statement in the @implementation block, explicitly declaring the name of the … Read more
The compiler treats this as below; basically, the code in the constructor writes to the original backing field, in TestBase. It seems that yours is not a supported scenario, but… I do wonder whether the language team have considered this case. BTW: if you ever want to see what the compiler does with code: sharplab.io … Read more
What’s happening here is the deserializer is trying to guess the name of your backing fields. You can solve this by adding explicit mappings (DataContract/DataMember attributes) like this: [DataContract] public class Cat { [DataMember] public string Name { get; set; } [DataMember] public string Breed { get; set; } }
Because you might want a read-only property: public int Foo { get; private set; } Or Write-only property: public int Foo { private get; set; }
Properties can have code put into them without breaking contract, fields can’t have code put into them without changing them to properties (and breaking the interface). Properties can be read only or write only, fields can’t. Properties can be data bound, fields can’t.
Note: as of C# 6, this isn’t required – but you should be using read-only automatically-implemented properties with C# 6 anyway… this() makes sure that the fields are definitely assigned as far as the compiler is concerned – it sets all fields to their default values. You have to have a fully constructed struct before … Read more
From C# 6 onward: this is no longer a problem Becore C# 6, you need to call the default constructor for this to work: public MyStruct(int size) : this() { Size = size; } A bigger problem here is that you have a mutable struct. This is never a good idea. I would make it: … Read more
Properties don’t need backing variables (fields) at all. While they can be used for encapsulating simple fields you can also use them to access other data. public Decimal GrandTotal { get { return FreightTotal + TaxTotal + LineTotal; } } or public string SomeStatus { get { return SomeMethodCall(); } } If the goal is … Read more
