How to convert a string to an integral number type array in C#?

Question

I want to convert the following string to an array of an integral number type.

string str = "-9007199254740985";

I tried str.ToArray().ToString(); but did not get the right conversion.

Answer 1

If you want to convert the string to an array, you can do it like this.

var array = new string[] { str };

However, if you want an array of long , you have to convert your string first.

var number = long.Parse(str);

Then you can add it to an array.

var array = new long[] { number };

Note that you cannot use an int here, because your number exceeds its range .

Answer 2

Below code will convert the string to character array.

string input = "welcome";
char[] chars = input.ToCharArray();
