| Well, suppose you have the following string:
|
| "Item #1: $32.53 Item #2: $32.54 Sub-Total: $65.07"
|
| With sscanf, I believe you can do something like:
|
|
| sscanf(buff, "Item #1: $%d Item #2: $%d Sub-Total: $%d", value1, value2,
| value3);
| printf("Sub-Total: %d", value3);
|
|
| Using regex, you can do something similar...and parsing out yourself
would
| be more trickier...

I prefer using TryParse over RegEx, just a matter of taste, and quite
faster
;-)

// suppose the current culture is en-US...
Decimal decVal;
string tokenString = "Item #1: $32.53 Item #2: $32.54 Sub-Total:
$65.07";
string [] split = tokenString.Split(new Char [] {' '});
bool result = Decimal.TryParse(split[7], NumberStyles.Currency, null,
out decVal);
if(result)
Console.WriteLine("Sub-total: {0:c}", decVal);

Not really tricky IMO.

grr, that's not my point. The OP requested similar functionality to sscanf.
The closest he can get is by using Regex...sure, you can parse it yourself
into an array and access the individual elements, but that's not what the OP
was originally asking AFAIK (even though, it should work for the OP).
Anywho :)
