c# - Get yesterday's date from the date entered -



c# - Get yesterday's date from the date entered -

i have console application accepts date parameter. however, date passed string in format:

string dt = datetime.now.tostring("yyyymmdd");

once date entered need programmatically day - 1 entered date. since string, cannot calculation.

for example, user enters:

20141023

i need subtract day date get:

20141022

i did quick prepare solve immediate need, however, not right way , has bug:

int yt = int32.parse(dt) - 1;

and turn around , convert yt.tostring()

the above solution not work if it's 1st of month.

is there way can programmatically yesterday's date in format (yyyymmdd) without changing format , perchance not using timespan?

try this...

datetime info = datetime.parseexact("20141023", "yyyymmdd", cultureinfo.invariantculture); console.writeline("{0} - {1}", data, data.adddays(-1).tostring("yyyymmdd"));

c# date console-application
