Question

I have made an array that take an input say “12345” and splits it down into the following

0 – 1
1 – 2
2 – 3
3 – 4
4 – 5

I then shuffle these numbers up a little to get

0 – 5
1 – 2
2 – 3
3 – 4
4 – 1

Once this is done i want to return the take this array and create an int of the new order , so the output i want is “52341”

I though i had solved this up I an the following error when I run my code ‘Input string was not in a correct format.’

So here is my code and can anyone help?

C#

string result = number[i].ToString();
var intList = result.Select(digit => Int64.Parse(digit.ToString()));
Int64[] Circle = intList.ToArray();

int order = Circle.Length;
int check = 0;
while (check < order)
{
    numholder = Circle[0];
    Array.Copy(Circle, 1, Circle, 0, Circle.Length - 1);

    Circle[order - 1] = numholder;
    //string p = Circle.ToString();
    //string p = Circle.ToString();
    Int64 h = Int64.Parse(Circle.ToString());

Answer 1

I think your problem is in this line:

Int64 h = Int64.Parse(Circle.ToString());

This is because Circle.ToString() returns Int64[], and this isn’t the correct Int64

I think you should use this line with String.Join:

Int64 h = Int64.Parse(String.Join("", Circle));
