[edit] C# Function Overloading
Overloading is the idea of having multiple functons that are the same name. Each function must accept different types or amount of types. This is how the compiler differentiates from overloaded functions.
Example 1:
using System;
class Program
{
static void Function(int x) //Accepts an int
{
x = 12;
Console.WriteLine(x + " is an int");
}
static void Function(long x) //Accepts a long
{
Console.WriteLine(x + " is an long");
}
static void Main()
{
int a = 12;
long b = 12;
Function(a); //passing an int value
Function(b); //passing a long value
Console.Read();
}
}
Output:
12 is an int
12 is a long
Example 2:
using System;
class Program
{
static void Function(int x) //Accepts one parameter
{
x = 12;
Console.WriteLine(x + " is an int");
}
static void Function(int x, int y) //Accepts two parameters
{
Console.WriteLine(x + " and " + y + " are int");
}
static void Main()
{
int a = 12;
int b = 12;
int c = 12;
Function(a); //passing one value
Function(b, c); //passing two values
Console.Read();
}
}
Output:
12 is an int
12 and 12 are int
The are more ways to give the compiler hints that functions are different. These are just a couple of ways I have presented. C# function overloading is a powerful tool. With overloading your code will be somewhat shorter and can decrease development time. Overloading does not have any performance benefits infact it has a minute performance hit because the compiler must choose which function to call. This decision takes a very small amount of time.
