Question

string sequence = "12345";
int[] ziffern = new int[sequence.Count()];
for (int i = 0; i < sequence.Count(); i++)
{
    ziffern[i] =  Convert.ToInt32(sequence.ElementAt(i));
}

It does not work like that. How can I access every single number?

Answer 1

ElementAt will return a char.

When you convert a char to an Int32, you will get the ASCII code of the character.

Try this:

 string sequence = "12345";
 int[] ziffern = new int[sequence.Length];
 for (int i = 0; i < sequence.Length; i++)
 {
       ziffern[i] = Convert.ToInt32(sequence.Substring(i, 1));
 }
