Type conversion and method overloading

In this chapter you will learn:

  1. How is the type conversion affecting the method overloading

Method type and method overloading

The following code shows automatic type conversions can affect overloaded method resolution.

using System; // jav a2 s. c  o m
 
class Overload2 { 
  public void f(int x) { 
    Console.WriteLine("Inside f(int): " + x); 
  } 
 
  public void f(double x) { 
    Console.WriteLine("Inside f(double): " + x); 
  } 
} 
 
class MainClass { 
  public static void Main() { 
    Overload2 ob = new Overload2(); 
 
    int i = 10; 
    double d = 10.1; 
 
    byte b = 99; 
    short s = 10; 
    float f = 11.5F; 
 
 
    ob.f(i); // calls ob.f(int) 
    ob.f(d); // calls ob.f(double) 
 
    ob.f(b); // calls ob.f(int) -- type conversion 
    ob.f(s); // calls ob.f(int) -- type conversion 
    ob.f(f); // calls ob.f(double) -- type conversion 
  } 
}

The code above generates the following result.
