          arr[1] = "Anil";
          arr[2] = "Raja";
          arr[3] = "Somu";
          for (int i = 0; i <= arr.Length; i++)
          {
              string element = arr[i];
              Console.WriteLine(element);
          }

Solution 1

It means that you are trying to get an element from the array at an index that exceeds the array's bounds. In this case, the maximum index is 3 (the array indices of C# are zero-based, that is, the first element has index 0), but because your condition is i <= arr.Length, i will be 4 at the last iteration of the loop, because the array length is 4. Change the condition to i < arr.Length and then your loop will work fine.
