Functions in C Sharp

All functions are part of a class, they're usually called methods.

private/public int myMethod (int param);

This method takes an int as input and returns an int.

[modifier] [return type] [founction name](parm)
{
// write code here
}
ie
public int add(int a,int b)
{
int sum=a+b;
return sum;
}

General Syntax :
[Access Modifier][Returned Data Type][function name](Paramters)

Ex :
1)
public int FunctionName (int x,int y)
{
// Your Custom Code go here
}

2)
Private Void Add(int x ,int y)
{
Console.WriteLine (x + y);
}
