Arrays in c# code example

Example 1: c# array

int[] array = new int[]{1, 2, 3, 4, 5};
foreach (string i in array) 
{
  Console.WriteLine(i);
}

//or

for(int i=0; i<array.Length; i++){
	  Console.WriteLine(array[i]);
}

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# array

int[] array = new int[]{1, 2, 3, 4, 5};
for(int i=0; i<array.Length; i++){
	  Console.WriteLine(array[i]);
}

Example 4: 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 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: array syntax c#

class TestArraysClass
{
    static void Main()
    {
        // Declare a single-dimensional array of 5 integers.
        int[] array1 = new int[5];

        // Declare and set array element values.
        int[] array2 = new int[] { 1, 3, 5, 7, 9 };

        // Alternative syntax.
        int[] array3 = { 1, 2, 3, 4, 5, 6 };

        // Declare a two dimensional array.
        int[,] multiDimensionalArray1 = new int[2, 3];

        // Declare and set array element values.
        int[,] multiDimensionalArray2 = { { 1, 2, 3 }, { 4, 5, 6 } };

        // Declare a jagged array.
        int[][] jaggedArray = new int[6][];

        // Set the values of the first array in the jagged array structure.
        jaggedArray[0] = new int[4] { 1, 2, 3, 4 };
    }
}
