Converting char to ASCII symbol

March 21, 2022

So I want to make "hello world!" in a creative way and I came up with and idea to use ASCII but I don’t realy now how to convert from char to ASCII symbol (neither from string). Here is my code:

public static void Main()
{
    List<string> imie = new List<string>();

    greet();
}
public static string greet()
{
    string s = "";
    string nums = "104 101 108 108 111 32 119 111 114 108 100 33";
    char[] numbers = nums.ToCharArray();
    foreach (char l in numbers)
    {
        s += Encoding.ASCII.GetChars(new byte[] {l});
    }

    return s;
}

Also in line "s += Encoding.ASCII.GetChars(new byte[] {l});" I am getting error "Cannot implicitly convert type ‘char’ to ‘byte’. An explicit conversion exists (are you missing a cast?)"

>Solution :

here you go

   public static string greet() {
        string s = "";
        string nums = "104 101 108 108 111 32 119 111 114 108 100 33";
        var numbers = nums.Split(" ");
        foreach (var nstr in numbers) {
            int k = Int32.Parse(nstr);
            s += Convert.ToChar(k);

        }

        return s;
    }

or better (appending to a string is very ineffiecint)

  public static string greet() {
        StringBuilder s = "";
        string nums = "104 101 108 108 111 32 119 111 114 108 100 33";
        var numbers = nums.Split(" ");
        foreach (var nstr in numbers) {
            int k = Int32.Parse(nstr);
            s.Append(Convert.ToChar(k));

        }

        return s.ToString();
    }
