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 to the array bounds minus one as we did in the above 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] = j;



Arrays in C# are dynamic and space can be reallocated at any time. To create a reference to an array and allocate it later within the class, use the syntax:


float z[]; //declare here

z = new float[20]; //create later
