Understanding this code snippet

Question

Can anyone tell me what does this part of the code do? what is meant by 'get set' here? public struct XYZ { public bool A { get ; set ; } public bool B{ get ; set ; } public bool C { get ; set ; } }

Ranjan Dailata · Answer

Setting the default values to properties can be done at constructor level.

ali tuncer · Answer

A test = new A(true true true); //constructor called test.X = false; //set called Console.WriteLine(test.X); //get called

Sahil Dev · Answer

Thanksa lot.Sorry but foolish question can you tell when are the get and set called?

ali tuncer · Answer

public struct A { private bool _X; public bool X { get { return _X; } set { _X = value; } } private bool _Y; public bool Y { get { return _Y; } set { _Y = value; } } private bool _Z; public bool Z { get { return _Z; } set { _Z = value; } } public A(bool x bool y bool z) { _X = x; _Y = y; _Z = z; } } A test = new A(true true true); A test2 = new A(); Console.WriteLine(test.X); //display true Console.WriteLine(test2.X); //display false

Still not working even after defining parameters I get the following error during compilation Error 2 Backing field for automatically implemented property 'MyApplication.XYZ.A' must be fully assigned before control is returned to the caller. Consider calling the default constructor from a constructor initializer.

ali tuncer · Answer

you can't define a constructor without parameters you must have a parameter..

Sahil Dev · Answer

Yes I would like to define a constructor as suggested by ali tuncer public struct A { public bool X { get ; set ; } public bool Y { get ; set ; } public bool Z{ get ; set ;} public A { X=true; } } This doesn't allow. I get an error after compiling saying: Error 1 Invalid token '{' in class struct or interface member declaration .. Please an anyone help?

ali tuncer · Answer

It is possible this way: public struct XYZ { public bool _A; public bool _ATest; public bool A { get { if (!_ATest) { _A =true; _ATest=true; } return _A; } set { _ATest = true; _A = value; } } } XYZ s = new XYZ(); Console.WriteLine(s.A); // this will display true

ali tuncer · Answer

I don't think it is possible you can define a constructor with parameter and set it to true.. http://csharp.2000things.com/2010/10/03/108-defining-a-constructor-for-a-struct/
