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]);
}

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}; 

c# array

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

hwo to make an array in C#

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

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

arrays in c#

// There are actually many ways to create an array in C#

// The worst method
int[] array1 = new int[3];
array1[0] = 1;
array1[1] = 2;
array1[2] = 3;

// Declare a single-dimensional array of 5 integers
int[] array1 = new int[5];

// Declare and set array element values
int[] array2 = new int[5] { 1, 2, 3, 4, 5 };

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

// 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 };

c# arrays

ArrayList arlist = new ArrayList()
                {
                    1,
                    "Bill",
                    300,
                    4.5f
                };

arlist.Insert(1, "Second Item");

foreach (var val in arlist)
    Console.WriteLine(val); 

array declaration in c#

// Syntax: data_type[] variable_name = new data_type[size];

// Decalring array of integers of length 5
int[] intArr = new int[5];

// Declaring array of strings of length 5
string[] names = new string[5];

// We can also populate the array, if we know the elements in advance
int[] evenDigits = new int[] {0,2,4,6,8}; // notice that in this, we don't need explicit size declaration.

how to make a c# array

// Syntax: 
datatype_variable[dimension] = new datatype[size]{array};

// For example:
string MyArray[] = new string[1]{"Hello","World"};

// or just:
string MyArray[]={"Hello","world"};

// for multidimensions:
// 2D array:
         	  // 2 arrays, 3 values //
int MyArray=[,]=new int[1,2]{
  {1,2,3},
  {1,2,3}
}

// 3D array:
              // 2 arrays, 3 arrays, 4 values //
int MyArray=[,,]=new int[1,2,3]{
  {
    {1,2,3,4},
    {1,2,3,4},
    {1,2,3,4}
  },
  {
    {1,2,3,4},
    {1,2,3,4},
    {1,2,3,4}
  }
}

C# creating an array

//Creating an empty array
string[] myString;

//Creating an occupied array
int[] myNumbers = {3,7,9,12};
