Constructor to call on derived classes to skip initialization and merely allocate the object. CXCall(IntPtr) A constructor used when creating managed representations of unmanaged objects; Called by the runtime. CXCall(NSObjectFlag) Constructor to call on derived classes to skip initialization and...
The base keyword can be used to call the constructor of the base class from the constructor of the child class in C#.
Constructor chaining in C# is sharing initialization code across constructors in the same class or from the base class.
This constructor should be called by derived classes when they completely construct the object in managed code and merely want the runtime to allocate and initialize the NSObject. This is required to implement the two-step initialization process that Objective-C uses, the first step is to perform...

I have tried myself by making virtual constructor but compiler say that you cant make virtual cobstructors...I am literally confused..Kindly tell me..
嗷嗷按,今天被问到在constructor/destructor中调用virtual member function的问题。答错了,很羞耻。 依稀记得在constructor/destructor调用virtual member function不好,就随口答道不能调用,可能会出错。 后来仔细想想不对,羞耻呀。调用是可以的,从语言角度没错,只不过和其他情况下调用虚函数有些不同。

In general, if the developer's constructor invokes the NSObjectFlag.Empty base implementation, then it should be calling an Objective-C init method. If this is not the case, developers should instead chain to the proper constructor in their class. The argument value is ignored and merely ensur...
