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.

Answer: 
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}");

```
You can use Culture info while parsing number into German format

Try with this approach:

```
string.Format(System.Globalization.CultureInfo.GetCultureInfo("de-DE"), "{0:000,000.00}", <your number>)

```

for example:

```
 string result = string.Format(System.Globalization.CultureInfo.GetCultureInfo("de-DE"), "{0:000,000.00}", 202667.4)

```
