C Formatexception Error String To Datetime Stack Overflow

Sql Server Error Convert String To Datetime Stack Overflow If i had a guess at this, i think you may have a problem with string format of the date time value not being recognised due to the current culture value. the way i've always done datetime conversion is to use datetime.parseexact (). Datetime.parseexact("2021 12 02 05:55:50 pm", "yyyy mm dd hh:mm:ss tt", cultureinfo.invariantculture) works fine for me. but the last screenshot shows that you may get a 1 digit hour, so you probably should use yyyy mm dd h:m:s tt.

When dealing with a textbox that should be an int do not allow invalid entries e.g. disallow non in values then use inttryparse to weed out empty string and decimal double. You can potentially change the datetime to nullable, datetime? or check the strings you're passing in with string.isnullorempty() and add whatever logic you think's best to handle null values.
