C# Design Patterns: A Tutorial

Chapter 7. Arrays, Files, and Exceptions in C#

C# makes handling arrays and files extremely easy and introduces exceptions to simplify error handling.

Arrays

In C#, all arrays are zero based. If you declare an array as

int[] x = new int[10];

such arrays have 10 elements, numbered from 0 to 9. Thus, arrays are in line with the style used in C, C++, and Java.

const int MAX = 10; float[] xy = new float[MAX]; for (int i = 0; i < MAX; i++ ) {        xy[i] = i; }

You should get into the habit of looping through arrays from zero to the array bounds minus one, as we did in the preceding example.

All array variables have a length property so you can find out how large the array is.

float[] z = new float[20]; for (int j = 0; j< z.Length ; j++) {        z[j] ...
