A foreach loop executes some code for each element of a list or array. Works like this

List<int> list = new() { 1, 2, 3, 4, 5 };

foreach (int element in list)
{
    Console.WriteLine(element);
}

List<int> list = new() { 1, 2, 3, 4, 5 };

foreach (int element in list)
{
    Console.WriteLine(element);
}

Here we create a list, then loop through every element of it and print it to the console.

@thinker227 Oh,just like this in Python

list = [1,2,3,4,5]
for i in list:
  print(list[i])

list = [1,2,3,4,5]
for i in list:
  print(list[i])

thank you
