Hello,

I collect a string on my ASP.NET page via Request.QueryString.

For Example:
http://www.site.com/index.aspx?Outlook=BAD

I now want to take this string and convert it to a NUMERICAL string based on
the position within the alphabet.n Spaces OR Dashes between each character
is important

So,

BAD becomes 2-1-4
ADD becomes 1-4-4
AZA becomes 1-26-1
ABC becomes 1-2-3
XYZ becomes 24-25-26

Anyone got any ideas on how best to achieve this? The string needs to be
generated before page load or as the first item on page load.

Thanks for any help offered,

Regards,

Gary.

Loop through the characters in the input string,
Find the position of the character in a "alphabet string" (" ABCD...")
(Note: I added a space at the beginning, so 'A' is at position 1)
Add a '-' plus that position to the output string (maybe use
StringBuilder)
Finally, forget the first character of that output (a '-')

I question the design of whatever it is ur building. It seems
unecessary...but...assuming you know more about what ur building than I do
;) try:

int valueOfA = ((int)'A') - 1;
char[] chars = input.ToCharArray();
foreach (char c in chars)
{
int value = ((int)c) - valueOfA;
//value is now the numeric value
}
