c# foreach array in array code example

Example 1: c# loop through array

//iterate the array
for (int i = 0; i < arr.Length; i++)
{
  // loop ...
}
// or
foreach (var element in arr)
{
  // loop ...
}

Example 2: c# loop through array

int[] numberArray = { 4, 5, 6, 1, 2, 3, -2, -1, 0 };
foreach (int number in numberArray)
{
    System.Console.Write("{0} ", number);
}

Example 3: c# foreach arra

int[,] numbers2D = new int[3, 2] { { 9, 99 }, { 3, 33 }, { 5, 55 } };
// Or use the short form:
// int[,] numbers2D = { { 9, 99 }, { 3, 33 }, { 5, 55 } };

foreach (int i in numbers2D)
{
    System.Console.Write("{0} ", i);
}
// Output: 9 99 3 33 5 55

Example 4: c# foreach arra

int[] numbers = { 4, 5, 6, 1, 2, 3, -2, -1, 0 };
foreach (int i in numbers)
{
    System.Console.Write("{0} ", i);
}
// Output: 4 5 6 1 2 3 -2 -1 0
