Get numeric value of all characters in a string [duplicate]

Question

I want to get the decimal ASCII value of a string in C#, for instance:

"abc123s" would be: 97 98 99 49 50 51 115 (979899495051115) 'f1c3s1"would be:102 49 99 51 115 49or1024999511549`

I tried Convert.ToInt32 or Int.Parse but they do not result in the desired effect.

What method can I use for this?

Answer 1

Assuming that you're only working with ASCII strings, you can cast each character of the string to a byte to get the ASCII representation. You can roll the results back into a string using ToString on the values:

string str = "abc123s";
string outStr = String.Empty;

foreach (char c in str)
    outStr += ((byte) c).ToString();

You could also get the byte values as an array, and make the results into a string using String.Join:

byte[] asciiVals = System.Text.Encoding.ASCII.GetBytes(str);
outStr = String.Join(String.Empty, asciiVals);

Answer 2

Try

string all = "";

all = String.Join(String.Empty, "abc123s".Select(c => ((int)c).ToString()).ToArray());
