By "smallest" what do you mean? Does your homework need the fewest number of characters? The shortest IL? The quickest execution? Or what?
Real men don't use instructions. They are only the manufacturers opinion on how to put the thing together. Manfred R. Bihy: "Looks as if OP is learning resistant."

The only way you're going to "have" is to write it yourself. We're not going to write it for you, and frankly, this can be done in a single line of code. ...and this reeks of being a homework assignment.

(anti)hint: NumberFormat.DecimalSeparator does not accept an empty string. :)

That is an unusual requirement. However:
double d = 12.010;
string s = Math.Truncate(d * 100).ToString();

Or
d.ToString().Replace('.', string.Empty);
So many ways to do it, and as usual, the requirements exist in a fug of inadequacy.
I'm not a stalker, I just know things. Oh by the way, you're out of milk.
Forgive your enemies - it messes with their heads

I'm sorry to say, I see two problems with that: 1. it doesn't compile as Replace needs (char,char) or (string,string); 2. cultural differences may cause some other character to act as decimal point, a comma for instance. So I'd suggest
d.ToString(NumberFormatInfo.InvariantInfo).Replace(".", "");as the proper way to do it, and possibly""+(int)(100*d)as the shortest code (with overflow risks). :)Luc Pattyn [Forum Guidelines] [My Articles] Nil Volentibus Arduum

Don't be sorry. You are right after all.

Well, I do am sorry in a different way, as I didn't find a way to signal your code's weakness without violating Dave's hint not to answer homework questions in any detail. That must be the price to pay when coming late to a thread. :)

You might need a file for that.

Dave KreskowiakWhat... You need a WHOLE line. I could do it in 1/3 of a line... :)
I wasn't, now I am, then I won't be anymore.

Not as silly as you may think. I worked on a project once where the client provided long lists of products with decimal based prices, but where the database was setup to hold prices based in cents, not decimal dollars. A crappy design it was, but hands were tied they were.
I wasn't, now I am, then I won't be anymore.

I'll do it in a 1/3 of a line at 640x480. If you want to beat that, you'll have to "name that tune"!

The reason I posted mine is because, weaknesses from typing it up on a phone keyboard notwithstanding, it's a poor way of solving the problem - and then you went and corrected it. I ignored various edge cases, which you started to correct - shame on you ;P .

thank u for all, u really let me laughing very much with all u jokes responses :laugh: that is the real help I found a solution my self:
double x = 1458752.10254000;
string s = x.ToString(System.Globalization.CultureInfo.InvariantCulture).Replace(".",string.Empty);
Console.WriteLine(s);
Console.ReadLine();the output is :145875210254 thank u very much for u big effort in creating jokes. :laugh:
