ASP.NET Basics (part 6): Fully Function-al
Modularize your code in C# by abstracting it into functions.

| The Right Spirit |

Let's take a simple example, which demonstrates how to define a function and call it from different places within a C# script:


<script language="c#" runat="server">

// define a function
void guaranteedPickMeUp()
{
   Response.Write("Long Island Iced Tea");
}

void Page_Load()
{  

   // the first question...
   Response.Write("What's the only thing that cheers me up when I'm down?<br>");
  
   // call the function
   guaranteedPickMeUp();
  
   // ... followed by another
   Response.Write("<br>What contains a virtual menagerie of spirits, guaranteed to leave your head banging in the morning?<br>");
  
   // call the function
   guaranteedPickMeUp();
}
</script>
<html>
<head><title>A Few Drinks</title></head>
<body>
</body>
</html>


View it in your browser  - you should see something like this:

Let's take this line by line. The first thing I've done in my C# script is define a new function with the "function" keyword; this keyword is followed by the name of the function and the data type of the return value of the function. I have used "void" here because our function, in its current state does not return any value (more on this at a later date, though). In the example above, the function has been named "guaranteedPickMeUp".

All the program code attached to that function is then placed within a pair of curly braces - this program code could contain loops, conditional statements, calls to other functions, or calls to other C# functions. Function names are case-sensitive in C#, so be careful when invoking them.

Here's the typical format for a function:


return_data_type function_name ( optional function arguments )
{
   statement 1;
   statement 2;
   statement 3;
   .
   .
   .
   statement n;  
}
