All that is needed is    0 00   c  does the rest   Num ToString    0 00       The    0  formats the thousand separators  0 00  forces two decimal points

I had the same problem   I wanted to format numbers like the  quot General quot  format in spreadsheets  meaning show decimals if they re significant  but chop them off if not   In other words   1234 56   gt  1 234 56 1234       gt  1 234  It needs to support a maximum number of places after the decimal  but don t put trailing zeros or dots if not required  and of course  it needs to be culture friendly   I never really figured out a clean way to do it using String Format alone  but a combination of String Format and Regex Replace with some culture help from NumberFormatInfo CurrentInfo did the job  LinqPad C  Program   string FormatNumber lt T gt  T number  int maxDecimals   4        return Regex Replace String Format  quot  0 n quot    maxDecimals    quot   quot   number                              quot   quot    System Globalization NumberFormatInfo CurrentInfo NumberDecimalSeparator    quot   0   quot    quot  quot          void Main        foreach  var test in new     123  1234  1234 56  123456 789  1234 56789123             Console WriteLine test    quot     quot    FormatNumber test       Produces  123   123 1234   1 234 1234 56   1 234 56 123456 789   123 456 789 1234 56789123   1 234 5679

Maybe you simply want the standard format string  N   as in  number ToString  N     It will use thousand separators  and a fixed number of fractional decimals  The symbol for thousands separators and the symbol for the decimal point depend on the format provider  typically CultureInfo  you use  as does the number of decimals  which will normally by 2  as you require    If the format provider specifies a different number of decimals  and if you don t want to change the format provider  you can give the number of decimals after the N  as in  ToString  N2     Edit  The sizes of the groups between the commas are governed by the  CultureInfo CurrentCulture NumberFormat NumberGroupSizes   array  given that you don t specify a special format provider

Try with  ToString      0 00     From MSDN   The  0  custom format specifier serves as a zero-placeholder symbol  If the value that is being formatted has a digit in the position where the zero appears in the format string  that digit is copied to the result string  otherwise  a zero appears in the result string  The position of the leftmost zero before the decimal point and the rightmost zero after the decimal point determines the range of digits that are always present in the result string   The  00  specifier causes the value to be rounded to the nearest digit preceding the decimal  where rounding away from zero is always used  For example  formatting 34 5 with  00  would result in the value 35
