将数据库中的日期与DateTime.Now比较

Question

I have database table in which the dates are stored in the following format

I need to compare the current system date with the date stored in the db. I get the system date using DateTime.Now

But since these 2 dates are in different formatting... how can i convert and compare so that i can select only the required values.

Answer 1

Try this: Get only date from system datetime and compare with database date column value

You also get only date from database

//Database
SELECT CONVERT(date, Transaction_Date) FROM TableName

//Application
if(DateTime.Now.Date==databasedate)

Answer 2

If your database column is datetime format then after pull out data and store in a datetime type variable both will be a C# DateTime instance, So you can compare them without any format specification

DateTime date1 = DateTimeFromDb;
DateTime date2 = DateTime.Now;
int result = DateTime.Compare(date1, date2);

if(result == 0 )
  Console.WriteLine("Same")
