sscanf in c#

AMP
Hello,
Anybody know if anything exists like sscanf in c.
I found a few things OL but most were pretty old. Maybe something has
come along since 2004?
Thanks
Mike

Yup, regular expressions :) Regex library.

Search the doc's for String.Format, this is the closest you can get.

If I remember correctly, sscanf doesn't format output, it reads input from a
pre-formatted string. For that, you can use regular expressions.

Sorry I misread the OP's post, was thinking of scanf, anyway you don't need
regex.

You can also use a StringReader

Ignore my previous post.
Using Parse and TryParse methods you can achieve the same (and more) results
as sscanf in C.
Consider following sample....

static void Main()
{
string tokenString = "12 25 56 4";
string [] split = tokenString.Spl it(new Char [] {' '});
int Int32Val;
char charVal;
float floatVal;
bool result = Int32.TryParse( split[0], NumberStyles.In teger, null, out
Int32Val);
if(result)
Console.WriteLi ne(Int32Val);
result = Char.TryParse(s plit[1][0].ToString(), out charVal);
if(result)
Console.WriteLi ne(charVal);
result = Single.TryParse (split[2], NumberStyles.Fl oat, null, out
floatVal);
if(result)
Console.WriteLi ne("{0:f}", floatVal);
}
This should output:

12
2
56,00

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.Spl it(new Char [] {' '});
bool result = Decimal.TryPars e(split[7], NumberStyles.Cu rrency, null,
out decVal);
if(result)
Console.WriteLi ne("Sub-total: {0:c}", decVal);

Not really tricky IMO.

Willy.

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 :)
