Method Overloading
With method overloading, most methods can have the same name and different parameters:
Example
int MyMethod(int x)
float MyMethod(float x)
double MyMethod(double x, double y)Consider the following example, which involves two ways of adding numbers:
Example
static int PlusMethodInt(int x, int y)
{
return x + y;
}
static double PlusMethodDouble(double x, double y)
{
return x + y;
}
static void Main(string[] args)
{
int myNum1 = PlusMethodInt(8, 5);
double myNum2 = PlusMethodDouble(4.3, 6.26);
Console.WriteLine("Int: " + myNum1);
Console.WriteLine("Double: " + myNum2);
}Instead of defining two ways to do the same thing, it is better to overload one.
In the example below, we overload the PlusMethod method to work for both int and double:
Example
static int PlusMethod(int x, int y)
{
return x + y;
}
static double PlusMethod(double x, double y)
{
return x + y;
}
static void Main(string[] args)
{
int myNum1 = PlusMethod(8, 5);
double myNum2 = PlusMethod(4.3, 6.26);
Console.WriteLine("Int: " + myNum1);
Console.WriteLine("Double: " + myNum2);
}
