How Can I Call One Constructor from Another to Avoid Duplicating Code in C#?

Efficient Constructor Chaining in C#

This example demonstrates a common C# coding challenge: avoiding redundant code within multiple constructors while preserving readonly field integrity. The solution leverages constructor chaining to elegantly address this issue.

The provided code features a constructor accepting a string argument. Instead of directly assigning and calculating field values within this constructor, it cleverly delegates this responsibility to another constructor using the this(int.Parse(str)) syntax. This calls the constructor that accepts an integer argument.

This technique promotes code reuse and ensures consistent field initialization, regardless of the constructor used. The field initialization logic is separated from the data source, resulting in cleaner, more maintainable, and extensible code. Constructor chaining offers a superior approach to managing constructor logic in such scenarios.
