C# make an 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# 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 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: 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}
  }
}
