您可以使用日期比较方法是时候检查日期了.
例如:

you can use the Compare method of date time to check the date.
for example:

DateTime date1 =  Convert.ToDateTime(txtbox1.Text);
DateTime dt = DateTime.Now;
int result = DateTime.Compare(date1, dt );
string relationship;

if (result < 0)
   relationship = "is earlier than";
else if (result == 0)
   relationship = "is the same time as";         
else
   relationship = "is later than";
