Hello, I am getting some difficulty to remove the comma from a textBox.
The textBox receives a value (1,250) but I need it to show (1250) instead.

textBoxResult.Text = value1.ToString();

Any ideas?

Thanks a lot.

What I have tried:

Tried to use

textBoxResult.Text = value1.ToString("N0");

Please, read these:
Custom numeric format strings | Microsoft Docs[^]
Standard numeric format strings | Microsoft Docs[^]

You need to understand that displaying numbers in specific format depends on regional settings!

C#

double dblValue = -12445.6789;
Console.WriteLine(dblValue.ToString("N", CultureInfo.InvariantCulture));
// Displays -12,445.68
Console.WriteLine(dblValue.ToString("N1",
                  CultureInfo.CreateSpecificCulture("sv-SE")));
// Displays -12 445,7

I fully agree with you on this Maciej; not knowing which culture the OP is actually using, I just assumed the invariant culture, for which the floating format does not have any thousand separator.

Worked perfectly, thanks a lot!

But it covers your real issues...
See, solution #3.

How does it cover his real issues?

Maciej Los 21-Apr-20 2:18am

Well, the shortest way to explain it is to use example...

var myvalue = 1000.50;

//defult regional settings
//"En-us"
Console.WriteLine(myvalue.ToString("F1").Replace(",", ""));
//result: 1000.5

CultureInfo prs = new CultureInfo("Pl-pl");
//Polish regional stettings
Console.WriteLine(myvalue.ToString("F1", prs).Replace(",", ""));
//result: 10005

Conclusion?

Cheers!

His "real issue" was removing a comma from a string. His question didn't mention or imply the desire to make it culture specific. His example was to go from "1,250" to "1250". My solution is precisely what he asked for, and he marked it as "the answer".

Called to the board...
To be honest - if solution is getting marked by the questioner as an answer, that doesn't prove that it resolves issue at all.
I was trying to explain (on example) that removing comma while converting numer of 1,250 to string is proper way to resolve issue in His OS. When His program will be used on machine with different regional settings, the method you provided will be a cause of several problems.

Don't get me wrong. I'm not going to verbal skirmish with you.

Cheers,
Maciej
