for each in array C# 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# 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 3: c# loop through array

for (int i = 0; i < theData.Length - 2; i+=3) 
    { 

        // use theData[i], theData[i+1], theData[i+2]

    }
