does foreach iterate through all dimensions of a list 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# loop through array

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

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

    }
