Question

c# decimal.toString() conversion problem

Answer 1

Then your current culture's NumberDecimalSeparator is , instead of ..

If that's not desired you can force the dot with CultureInfo.InvariantCulture:

decimal num = 0.1m;
string numWithDotAsSeparator = num.ToString(CultureInfo.InvariantCulture);

or NumberFormatInfo.InvariantInfo

string numWithDotAsSeparator = num.ToString(NumberFormatInfo.InvariantInfo)
