需要将双精度或十进制转换为字符串

Question

我需要将 double 转换为字符串，其中两个十进制数字用“点”分隔我担心点必须始终用作分隔符。

Answer 1

最简单的方法是指定CultureInfo.InvariantCulture作为文化，例如

string text = d.ToString("N2", CultureInfo.InvariantCulture);

Answer 2

Perhaps to avoid messing up with CultureInfo settings on clients systems, we better set a concrete way to force the machine to use dot as decimal separator and not thousand separator ==> regardless of culture! So,

NumberFormatInfo fi= new NumberFormatInfo();
fi.NumberDecimalSeparator = ".";
string doubleDotDecimalNr = doubleNr.ToString(fi);
