I'm using C#.
I have a string array as follow: "1,2,3,4,5,..."
I'm trying to convert the string array to byte array as follow []{1,2,3,4,5,...}
What is the best way to do that?
Thanks.

Try using Linq:
string source = "1,2,3,4,5";
byte[] result = source
.Split(',')
.Select(item => byte.Parse(item))
.ToArray();

byte[] byteArray = str.Select(s => Convert.ToByte(s, 16)).ToArray();
Str represent string[]. If you have string you should string[] str = string.Split(',');

This doesn't compile because the base argument is only applicable when the first argument is a string. In your code,
s is type char. I get the following error: Argument 2: cannot convert from 'int' to 'System.IFormatProvider' In addition, this will include the commas as arguments.

@ChrisDunaway Str is string array the question is string array to byte array.

I re-read the question and though the OP used the words "string array", I believe they actually had a
string and not a real string[] to begin with. The accepted answer seems to support this assumption. I agree that your answer is valid given that str is really a string[].mybirthname
@ChrisDunaway I edit it, I'm from mobile so I have limited possibilities for formatting.
byte[] result = Array.ConvertAll(str.Split(','), Convert.ToByte);
