Instead of replace we can force culture like  var x   decimal Parse  18 285   new NumberFormatInfo     NumberDecimalSeparator             it will give output 18 285

All this is about cultures  If you have any other culture than  US English   and also as good manners of development   you should use something like this   var d   Convert ToDecimal  1 2345   new CultureInfo  en-US         or 1 2345 with your local culture  for instance     obviously  you should replace the  en-US  with the culture of your number local culture   the same way  if you want to do ToString    d ToString new CultureInfo  en-US

You are viewing your decimal or double values in Visual Studio  That doesn t respect the culture settings you have on your code   Change the Region and Language settings on your Control Panel if you want to see decimal and double values having the comma as the decimal separator
