Taking string Input and making a int array

Question

How do I take an string input and make it into an int array?

string input = Console.ReadLine();
int numb = Convert.Toint32(input);          
int[] intArray = // what do i write here to make it take the "input" length, and put the input into an int array?

Can you give example of input string and what the output should be for that string? — Floremin, Apr 15 '13 at 21:22

You don't give much detail, but if the input is a comma-delimited list of numbers you could do:

string input = "1,2, 3,4  ,5 ,6";  // string to simulate input
int[] numbers = input.Split(new char[] {','})
                     .Select(s => int.Parse(s))
                     .ToArray();

this will obviously blow up if any string between commas is not a valid integer.

You can get an array from a string in two different ways.

You can either use the split method, which breaks the string into an array of substrings - and then you'd have to parse each element of this array. This is probably what you want, since it seems you want an array of integers;

Or you can convert the string to a byte array. Means to do so have been discussed in this question. Then you convert those values to integers as you see fit.

string input = Console.ReadLine();
int numb = Convert.ToInt32(input);
int[] intArray = new int[numb];
for (int i; i < intArray.length; i++)
{
   intArray[i] = numb;
}

For obtaining the length of the input you can do the following:

    string input = Console.ReadLine();
    int numb = input.Length;
    int[] intArray = new int[1];
    intArray[0] = numb;
