C Sharp (C#) - Inheritance

Which of the following is the correct syntax to chain constructors in C#?

Apublic MyClass() : base() { }

Bpublic MyClass() : this() { }

Cpublic MyClass() : this(5) { }

Dpublic MyClass() { this(); }

Step-by-Step Solution

Solution:

Step 1: Recall constructor chaining syntax
Constructor chaining uses : this(parameters) after the constructor signature to call another constructor in the same class.
Step 2: Analyze options
public MyClass() : this(5) { } uses : this(5) which correctly calls another constructor with an int parameter. public MyClass() : this() { } calls itself recursively causing error. public MyClass() : base() { } calls base class constructor, not chaining. public MyClass() { this(); } tries to call constructor inside body, which is invalid.
Final Answer:
public MyClass() : this(5) { } -> Option C
Quick Check:
Constructor chaining syntax = : this(...) [OK]

Quick Trick: Use ': this(...)' after constructor signature to chain [OK]
