thank u for all,
u really let me laughing very much with all u jokes responses 
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.

Let's say that your Double is double lifeSpan.
string ls = lifeSpan.ToString().Replace(".","");

I've created a abstract class that is based upon a BindingList<t>, then I have classes based upon that abstract that should populate the list.
The idea being if you instaniate these secondary classes you have a useable list.
This works in code, creating a new class does populate the list.
However I know want to move to the next step, and use the seconday class as a binding source. But the problem is that binding doesn't seem to call the constructor of the class, and so my list is empty. (apart from that the binding seems to be working)
I can work around this by adding a BindingSource.DataSource = new SecondaryClass(); to the form etc...basically I'd like to avoid this step if possible?
Hopefully that makes sense?!?

Hi,
I write a txt file using streamwriter class :
StreamWriter monStreamWriter = new StreamWriter(myPath, true, System.Text.Encoding.ASCII);
monStreamWriter.WriteLine(strEnteteHead + Inserer_Espaces(8) + entite.NumSIRET + Inserer_Espaces(7) + strDate + domicilationbancaireE + referenceVir + Inserer_Espaces(15) + strEuro + Inserer_Espaces(5) + guichetE + compteE + Inserer_Espaces(20) + agenceE );
monStreamWriter.WriteLine(strEnteteBody +Inserer_Espaces(8) + agenceD + reglement.ID + reglement.Nom + reglement.Banque + Inserer_Espaces(12) + agenceD + compteD + reglement.Montant + agenceD);
monStreamWriter.WriteLine(strEnteteSum + reglement.Montant.ToString());
monStreamWriter.WriteLine();
monStreamWriter.WriteLine ();
the problem that i wanna that i have a new line every monstreamWriter.writeline. That is what i don't have when I open my txt file.
what is the problem??

Not sure what your problem is; this:
string fn="swl.txt";
using (StreamWriter sw=new StreamWriter(fn, true, Encoding.ASCII)) {
sw.WriteLine("line 1");
sw.WriteLine("line 2");
sw.WriteLine();
sw.WriteLine();
sw.WriteLine("line 5");
sw.WriteLine("line 6");
sw.WriteLine();
sw.WriteLine();
}
string[] sa=File.ReadAllLines(fn);
foreach (string s in sa) log(s);
log("done");
works just fine for me, as it generates:
16:14:29.329 CPTest.log-59 line 1
16:14:29.335 CPTest.log-59 line 2
16:14:29.341 CPTest.log-59
16:14:29.347 CPTest.log-59
16:14:29.353 CPTest.log-59 line 5
16:14:29.358 CPTest.log-59 line 6
16:14:29.364 CPTest.log-59
16:14:29.369 CPTest.log-59
16:14:29.375 CPTest.log-59 done
The obvious way to make things fail would be by reassigning the streamwriter's NewLine property.

Hi Luc,
I don't understand u answer "The obvious way to make things fail would be by reassigning the streamwriter's NewLine property"
Ty

For a StreamWriter sw
sw.WriteLine(something);
is equivalent to
sw.Write(something);
sw.Write(sw.NewLine);
and NewLine by default equals Environment.NewLine, which holds "\r\n" on Windows.
So if you set sw.NewLine=""; then there will not be any line breaks.
BTW: as usual, it is all in the documentation.

I don't think the problem is your code but with notepad.
Notepad (which I think you're using) doesn't accept newline characters very well or simply doesn't show.
Try opening it with wordpad or word, that might 'fix' your problem.

hi,
U answer works well in first use (opening with word pad) but when I repeat the action (opening file with wordpad) still the same problem (all lignes in same ligne).This what I have

absolutely not.
"have a coffee" would be better advice.

Why not? He doesn't seem to be closing the stream. Maybe those missing lines are still in the buffer?
|

flush does not close.
close (or dispose) does flush. (hence: the sequence flush+close does not make sense).
if the file wasn't closed, the file would be most likely be unreadable.
from his (rather incomplete) description, I get it there is data in the file, so it got closed, and an extra flush wouldn't change a thing.
flush is abused a lot; there is exactly one situation where an unnecessary flush does solve a problem that is caused by an entirely different mistake in the code, but there are no signs it applies here.

Data can end up in the file, even if it is not closed. When the StreamWriter buffer fills (default: 4KB), that portion is written to file.
To modify your earlier example (omitting the "using" statement, thereby denying a close):
string fn = "swl.txt";
StreamWriter sw = new StreamWriter(fn, true, Encoding.ASCII);
sw.WriteLine("line 1");
sw.WriteLine("line 2");
sw.WriteLine();
sw.WriteLine();
sw.WriteLine("line 5");
sw.WriteLine("line 6");
sw.WriteLine();
sw.WriteLine();
Nothing is written to the file. However, when I use:
string fn = "swl.txt";
StreamWriter sw = new StreamWriter(fn, true, Encoding.ASCII);
sw.WriteLine("line 1");
sw.WriteLine("line 2");
sw.WriteLine();
sw.WriteLine();
sw.WriteLine("line 5");
sw.WriteLine("line 6");
for (int i = 0; i < 5000; i++) sw.Write("X");
sw.WriteLine();
sw.WriteLine();
sw.Write("Will not go in file.");
I have exceeded the buffer, and the first 4K writes. When I run this code, I get a file with the lines up to the "for" statement, plus many "X" characters, but none of the later lines are "written". The file is readable, just incomplete after the program closes.

I know all that. The logical conclusion is one needs to close, not flush, the file (or better: all objects that are to contribute to the file content, in the reverse order in which they were opened). And that is what I did in my very first reply.

Hi Luc,
I read u discussion but i can't conclude the solution I can adopt even after adding this 2 lines of code
string endOfLine = new string (new char [] { (char)0x0D, '\n' });
monStreamWriter.WriteLine(strEnteteSum + Inserer_Espaces (8) + Inserer_Espaces (6) + Inserer_Espaces (84) + montant + endOfLine);
but still not organized right now

if you want to solve a problem, any problem, the first thing to do it to describe it as accurately as possible. "not organized right" is in no way an accurate description, I can't help any further based on just that.
Use the right tool to look at the output and tell us what it is and what you want it to be. For problems with CR/LF Notepad probably isn't the right tool, at best you'd use a Hex Viewer/Hex Editor as Pete already told you.

Hi Luc,
I want to have a file having as formats DOS/Windows and so its lignes have as end of line the two characters CR+LF.
When I open my file with Excel, all lines are in the same line, no considering of endofline that I added to my code and the use of the stringbulder class like this :
StringBuilder lineBuilder = new StringBuilder ();
lineBuilder .Append (headLine);
lineBuilder.Append (endOfLine);

if you run on Windows, never touch any NewLine property, and simply create a text file in a normal way, with data that is ASCII representable, then the file will be an ASCII file (8b/char) and every WriteLine will insert a CR+LF.
If you aren't getting CR+LF it tells me you are doing something special, I don't know what as there is a lot you still haven't told. If you need any further help, state your operating system, your .NET version, the kind of characters you are having, and all the code of the smallest app that goes wrong.

Pierre besquent wrote: what is the problem??
You are using WriteLine() so in fact you do have a 'new line'.
So you have some other problem.
I suggest that you start with NEW code (not existing code) as a console application which does NOTHING but print some text to a file.
If that does not work then post the entire class that doesn't work and ALSO post
1. The OS you are using
2. The editor you are using.

Hi,
I did what u proposed ( I use windows XP and open txt files with word pad)
still the same problem: nnnnnnnno returning to line
plz help me i am so closed

One of my proposals was specific in the regard to what you should do if you still had a problem.
You did not follow through with that.

Hi,
U advice are so interessant. It helps me sssssssssssso to find a solution of my problem.These is the two steps that solves my problem:
1- using of string builder concept:
StringBuilder lineBuilder = new StringBuilder ();
headLine = strEnteteHead + strNumLine;
lineBuilder .Append (headLine);
lineBuilder.Append (endOfLine);
then englobing it in my streamwriter:
monStreamWriter.WriteLine(lineBuilder.ToString());
monStreamWriter.Close();
return monStreamWriter;
2- Doing one Response.write ( not like I do in the begining) when reading my file with streamreader
StreamReader report = (StreamReader)GGetValue ("_Report");
this.Response.Write (report.ReadToEnd().ToString ());
Now, orpning my file with all (word , wordPad, EXCEL,...),lines are sssssso clear
Thank u for u help
