Delphi for .NET Developer’s Guide

User-Defined Types

Integers, strings, and floating-point numbers often are not enough to adequately represent variables in the real-world problems that programmers must try to solve. In cases like these, you must create your own types to better represent variables in the current problem. In Delphi, these user-defined types usually come in the form of records or classes; you declare these types using the Type keyword.

Arrays

The Delphi language enables you to create arrays of any type of variable. For example, a variable declared as an array of eight integers reads like this:

var
  A: Array[0..7] of Integer;

This statement is equivalent to the following C# declaration:

int A[8];

It’s also equivalent to this Visual Basic .NET statement:

Dim A(8) ...
