Convert string to decimal keeping fractions

Question

I am trying to convert 1200 00 to decimal  but Decimal Parse   removes  00  I ve tried some different methods  but it always removes  00  except when I supply a fraction different than 0   string value    1200 00     Method 1   var convertDecimal   Decimal Parse value    NumberStyles AllowThousands          NumberStyles AllowDecimalPoint   NumberStyles AllowCurrencySymbol     Method 2   var convertDecimal   Convert ToDecimal value     Method 3  var convertDecimal   Decimal Parse value         NumberStyles AllowDecimalPoint  CultureInfo InvariantCulture     How can I convert a string containing 1200 00 to a decimal containing 1200 00

I think your problem is when displaying the decimal, not the contents of it.

If you try

string value = "1200.00";
decimal d = decimal.Parse(s);
string s = d.ToString();

s will contain the string "1200".

However if you change your code to this

string value = "1200.00";
decimal d = decimal.Parse(s);
string s = d.ToString("0.00");

s will contain the string "1200.00" as you want it to do.

EDIT

Seems I'm braindead early in the morning today. I added the Parse statements now. However even my first code will output "1200.00", even if I expected it to output "1200". Seems like I'm learning something each day, and in this case obviously something that is quite basic.

So disregard this a an proper answer. We will probably need more code to identify your problem in this case.

You can try calling this method in you program   static double string double string s                double temp   0          double dtemp   0          int b   0          for  int i   0  i  lt  s Length  i                          if  s i                                        i                    while  i  lt  s Length                                        dtemp    dtemp   10     int char GetNumericValue s i                        i                        b                                      temp   temp    dtemp   Math Pow 10  -b                    return temp                            else                               temp    temp   10     int char GetNumericValue s i                                    return -1    if somehow failed         Example   string s    12 3   double d   string double  s            d   12 3

decimal d   3 00 is still 3  I guess you want to show it some where on screen or print it on log file as 3 00  You can do following  string str   d ToString  F2      or if you are using database to store the decimal then you can set pricision value in database

Hmm    I can t reproduce this   using System   class Test       static void Main                         decimal d   decimal Parse  1200 00            Console WriteLine d      Prints 1200 00           Are you sure it s not some other part of your code normalizing the decimal value later   Just in case it s cultural issues  try this version which shouldn t depend on your locale at all   using System  using System Globalization   class Test       static void Main                         decimal d   decimal Parse  1200 00   CultureInfo InvariantCulture           Console WriteLine d ToString CultureInfo InvariantCulture
