c# declare int array code example

Example 1: c# initialize array

string[] stringArray = new string[6];
//or
int[] array1 = new int[] { 1, 3, 5, 7, 9 };
//
string[] weekDays = new string[] { "Sun", "Mon", "Tue", "Wed", "Thu", "Fri", "Sat" };
//etc

Example 2: c# create array of int

int[] array = new int[]; // []
int[] array = new int[5]; // [0, 0, 0, 0, 0]
int[] array1 = new int[] { 1, 3, 5, 7, 9 };

Example 3: c# create array

// Define and Initialize
int[] arr = {1, 2, 3};

// Buuuut:
// Initial defining
int[] arr;

// This works
arr = new int[] {1, 2, 3};   

// This will cause an error
// arr = {1, 2, 3};

Example 4: C# int array

int[,] array = new int[4, 2];
int[,] array2D_1 = new int[,] { { 1, 2 }, { 3, 4 }, { 5, 6 }, { 7, 8 } };
int[,] array2D_2 = new int[4, 2] { { 1, 2 }, { 3, 4 }, { 5, 6 }, { 7, 8 } };
int[,,] array3D = new int[2, 3, 4] { 
  									 { { 1, 2, 3, 4 }, { 5, 6, 7, 8 }, { 9, 10, 11, 12 } },
                                     { { 13, 14, 15, 16 }, { 17, 18, 19, 20 }, { 21, 22, 23, 24 } } 
                                   };

// array2D_1[0,1] = 2  
// array2D_2[1,0] = 3
// array3D[1,2,3] = 24

Example 5: hwo to make an array in C#

int[] Nameofarray = new int[how much is the max];

for example:
int[] X = new int[5];

Example 6: make new array in c#

string[] stringArray = new string[6];
