Convert number into culture specific

Question

I have a number like 202667.4. I want to convert this to number based on culture.

For Ex:

In "de"(German) the number should be in 202.667,40.

Any help will be greatly appreciated.

Thanks.

If you want to represent existing number (say, double) in culture specific format, try formatting:

https://learn.microsoft.com/en-us/dotnet/standard/base-types/standard-numeric-format-strings

double source = 202667.4;

// "n"  - ... group separators, and a decimal separator with optional negative sign  
// "de" - German culture
string result = source.ToString("n", CultureInfo.GetCultureInfo("de"));

Console.WriteLine(result);

Outcome

202.667,40

If you are given a string and you want a number, put Parse (TryParse):

string data = "202.667,40";

double result = double.Parse(data, CultureInfo.GetCultureInfo("de"));

Console.WriteLine(data.ToString(CultureInfo.InvariantCulture));

If you don't want to specify the culture each time you work with formatting, you can set the culture as a current one:

CultureInfo.CurrentCulture = CultureInfo.GetCultureInfo("de");

...

double source = 202667.4;

Console.WriteLine($"{source:n}");
