Converting double to string with N decimals, dot as decimal separator, and no thousand separator

Question

I need to convert a decimal to a string with N decimals (two or four) and NO thousand separator:

\'XXXXXXX (dot) DDDDD\'

The problem with CultureInfo.I

Answer 1

You can simply use decimal.ToString()

For two decimals

myDecimal.ToString("0.00");

For four decimals

myDecimal.ToString("0.0000");

This gives dot as decimal separator, and no thousand separator regardless of culture.
