Question

I am beginner to programming and c# , I want to convert a value which has minimum 6 digits into alphabetic form which also have the same number of Alphabets.I do not want to make it simple for user who have numerical value but he will not be able to guess its alphabetic value.that is the code i am trying to use.

   string a = input.Text;
   string temp = "ABCDEFGHIJKL";
   string ans = "";
   for (int i = 0; i < a.Length; i++)
   ans += temp[a[i] - 48];
   output.Text = ans;

Answer 1

So here is a method for you, solving what I’ve understand your problem is:

public string ConvertNumToAlpha(string numbers)
{
    string result = string.Empty;
    for (int i = 0; i < numbers.Length; i++)
    {
        result += Convert.ToChar(int.Parse(numbers.Substring(i, 1)) + 64);
    }
    return result;
}

And another “high-sophisticated encrypt” method:

public string EncryptNum(string numbers, string encryptString)
{
    string result = string.Empty;
    for (int i = 0; i < numbers.Length; i++)
    {
        result += encryptString.Substring(Math.Min(int.Parse(numbers.Substring(i, 1)), encryptString.Length) - 1, 1);
    }
    return result;
}
