C # - Replacing "." to "," in double meaning
I need to read a .txt and display it. Double values in data are written with ".". When I use German it doesn't interpret it as a comma. Now I tried to check if the language is set to German and replace all "." from ",". The values are stored in an array named "_value", but that doesn't work. Here is the code:
if ((System.Threading.Thread.CurrentThread.CurrentUICulture.TwoLetterISOLanguageName) == "de")
{
for (int i = 0; i < _value.Length; i++)
{
String temp_var = Convert.ToString(_value[i]);
temp_var.Replace(".", ",");
_value[i] = Convert.ToDouble(temp_var);
}
}

Instead of checking the language, you can also specify the culture from which the conversion is performed:
// Convert string to double from the invariant culture, which treats "." as decimal:
double d = Convert.ToDouble(_value[i], CultureInfo.InvariantCulture);
// Convert double to string using the current culture, which may happen to be German and uses a ",":
string s = Convert.ToString(d);
// Or convert double to string using the specific German culture:
string s = Convert.ToString(d, new CultureInfo("de-DE"));
I don't understand that apparently the array is _value
already double[]
, so these changes must be made earlier in your code where the conversion from string to double actually occurs.

Any reason you don't just temporarily install the appropriate culture
using System.Threading;
using System.Globalization;
Thread.CurrentThread.CurrentCulture = new CultureInfo("en-US");
