c# - Format of Convert.ToDateTime(string) method -

when execute convert.todatetime('08/01/2014') how convert 1-aug-2014 (ignore format) , not 8-jan-2014?

as far saw, there no mention of format string parameter being passed on method.

first of all, convert.todatetime("08/01/2014") not convert.todatetime('08/01/2014'). strings represents double quotes, not single quotes.

convert.todatetime(string) method uses currentculture iformatprovider default. here how it's implemented;

public static datetime todatetime(string value) {      if (value == null)          return new datetime(0);      return datetime.parse(value, cultureinfo.currentculture); } 

and datetime.parse(string, iformatprovider) implemented as;

public static datetime parse(string s, iformatprovider provider) {     return (datetimeparse.parse(s, datetimeformatinfo.getinstance(provider), datetimestyles.none)); } 

from documentation;

if value not null, return value result of invoking datetime.parse method on value using formatting information in datetimeformatinfo object initialized current culture. the value argument must contain representation of date , time in 1 of formats described in datetimeformatinfo topic.

so, datetimeformatinfo topic here exactly? datetimeformatinfo's information datetimeformatinfo.getalldatetimepatterns method.

most current thread culture has mm/dd/yyyy not dd/mm/yyyy (or character dateseparator of currentculture because "/" custom format specifier has special meaning replace me current culture or specified culture date separator) standard date , time format.

you can see standard date , time formats of currentculture with;

var patterns = cultureinfo.currentculture.                            datetimeformat.                            getalldatetimepatterns(); foreach (var format in patterns) {     console.writeline(format); } 

let me give example; current thread culture turkish (tr-tr). , has dd.mm.yyyy standard date , time format.

that's why when write convert.todatetime("02.01.2014") in code, parses string january 2nd not february 1st.

@sonergönül currentculture "en-us"! – salihdeen 3 mins ago

exactly said, en-us has mm/dd/yyyy not dd/mm/yyyy standard date , time format. that's why 08/01/2014 string parsed mm/dd/yyyy pattern not dd/mm/yyyy.

var patterns = cultureinfo.getcultureinfo("en-us").                        datetimeformat.                        getalldatetimepatterns(); foreach (var format in patterns) {     console.writeline(format); } 

result be;

m/d/yyyy m/d/yy mm/dd/yy mm/dd/yyyy <-- here! yy/mm/dd yyyy-mm-dd dd-mmm-yy dddd, mmmm dd, yyyy mmmm dd, yyyy dddd, dd mmmm, yyyy dd mmmm, yyyy dddd, mmmm dd, yyyy h:mm tt dddd, mmmm dd, yyyy hh:mm tt dddd, mmmm dd, yyyy h:mm dddd, mmmm dd, yyyy hh:mm mmmm dd, yyyy h:mm tt mmmm dd, yyyy hh:mm tt mmmm dd, yyyy h:mm mmmm dd, yyyy hh:mm dddd, dd mmmm, yyyy h:mm tt dddd, dd mmmm, yyyy hh:mm tt dddd, dd mmmm, yyyy h:mm dddd, dd mmmm, yyyy hh:mm dd mmmm, yyyy h:mm tt dd mmmm, yyyy hh:mm tt dd mmmm, yyyy h:mm dd mmmm, yyyy hh:mm dddd, mmmm dd, yyyy h:mm:ss tt dddd, mmmm dd, yyyy hh:mm:ss tt dddd, mmmm dd, yyyy h:mm:ss dddd, mmmm dd, yyyy hh:mm:ss mmmm dd, yyyy h:mm:ss tt mmmm dd, yyyy hh:mm:ss tt mmmm dd, yyyy h:mm:ss mmmm dd, yyyy hh:mm:ss dddd, dd mmmm, yyyy h:mm:ss tt dddd, dd mmmm, yyyy hh:mm:ss tt dddd, dd mmmm, yyyy h:mm:ss dddd, dd mmmm, yyyy hh:mm:ss dd mmmm, yyyy h:mm:ss tt dd mmmm, yyyy hh:mm:ss tt dd mmmm, yyyy h:mm:ss dd mmmm, yyyy hh:mm:ss m/d/yyyy h:mm tt m/d/yyyy hh:mm tt m/d/yyyy h:mm m/d/yyyy hh:mm m/d/yy h:mm tt m/d/yy hh:mm tt m/d/yy h:mm m/d/yy hh:mm mm/dd/yy h:mm tt mm/dd/yy hh:mm tt mm/dd/yy h:mm mm/dd/yy hh:mm mm/dd/yyyy h:mm tt mm/dd/yyyy hh:mm tt mm/dd/yyyy h:mm mm/dd/yyyy hh:mm yy/mm/dd h:mm tt yy/mm/dd hh:mm tt yy/mm/dd h:mm yy/mm/dd hh:mm yyyy-mm-dd h:mm tt yyyy-mm-dd hh:mm tt yyyy-mm-dd h:mm yyyy-mm-dd hh:mm dd-mmm-yy h:mm tt dd-mmm-yy hh:mm tt dd-mmm-yy h:mm dd-mmm-yy hh:mm m/d/yyyy h:mm:ss tt m/d/yyyy hh:mm:ss tt m/d/yyyy h:mm:ss m/d/yyyy hh:mm:ss m/d/yy h:mm:ss tt m/d/yy hh:mm:ss tt m/d/yy h:mm:ss m/d/yy hh:mm:ss mm/dd/yy h:mm:ss tt mm/dd/yy hh:mm:ss tt mm/dd/yy h:mm:ss mm/dd/yy hh:mm:ss mm/dd/yyyy h:mm:ss tt mm/dd/yyyy hh:mm:ss tt mm/dd/yyyy h:mm:ss mm/dd/yyyy hh:mm:ss yy/mm/dd h:mm:ss tt yy/mm/dd hh:mm:ss tt yy/mm/dd h:mm:ss yy/mm/dd hh:mm:ss yyyy-mm-dd h:mm:ss tt yyyy-mm-dd hh:mm:ss tt yyyy-mm-dd h:mm:ss yyyy-mm-dd hh:mm:ss dd-mmm-yy h:mm:ss tt dd-mmm-yy hh:mm:ss tt dd-mmm-yy h:mm:ss dd-mmm-yy hh:mm:ss mmmm dd mmmm dd yyyy'-'mm'-'dd't'hh':'mm':'ss.fffffffk yyyy'-'mm'-'dd't'hh':'mm':'ss.fffffffk ddd, dd mmm yyyy hh':'mm':'ss 'gmt' ddd, dd mmm yyyy hh':'mm':'ss 'gmt' yyyy'-'mm'-'dd't'hh':'mm':'ss h:mm tt hh:mm tt h:mm hh:mm h:mm:ss tt hh:mm:ss tt h:mm:ss hh:mm:ss yyyy'-'mm'-'dd hh':'mm':'ss'z' dddd, mmmm dd, yyyy h:mm:ss tt dddd, mmmm dd, yyyy hh:mm:ss tt dddd, mmmm dd, yyyy h:mm:ss dddd, mmmm dd, yyyy hh:mm:ss mmmm dd, yyyy h:mm:ss tt mmmm dd, yyyy hh:mm:ss tt mmmm dd, yyyy h:mm:ss mmmm dd, yyyy hh:mm:ss dddd, dd mmmm, yyyy h:mm:ss tt dddd, dd mmmm, yyyy hh:mm:ss tt dddd, dd mmmm, yyyy h:mm:ss dddd, dd mmmm, yyyy hh:mm:ss dd mmmm, yyyy h:mm:ss tt dd mmmm, yyyy hh:mm:ss tt dd mmmm, yyyy h:mm:ss dd mmmm, yyyy hh:mm:ss mmmm, yyyy mmmm, yyyy
