i have problem in find the date difference , i want date difference between two dates, one is coming from text box which is in format(dd/mm/yyyy)and other is coming from the Database so here is my problem while coming from data base it is having Datetime so i have to convert the date coming from text box into datetime but i am entering only date so i need to convert the date only in dateformat so is there any function to convert date into only date with date in C# here is my code.

decimal LoanAmt = Convert.ToDecimal(RepayloanAmountLbl.Text);
                        int Tenure = Convert.ToInt32(RepayTenureLbl.Text);
                        DateTime RepayStartDate = Convert.ToDateTime(StartDateTxt.Text);
                        //DateTime DisbursementDate = Convert.ToDateTime(RepayDateLbl.Text);
                        DateTime DisbursementDate = Convert.ToDateTime(dt.Rows[0]["REPAY_START_DATE"].ToString());
                        TimeSpan ts = RepayStartDate.Subtract(DisbursementDate);
                        int days = ts.Days;
                        decimal Rate = Convert.ToDecimal(RepayInterestLbl.Text) / 100;
                        decimal interest = ((LoanAmt * Rate) / 365) * days;
                        decimal X = (decimal)Math.Round(interest);
                        IntAmtTxt.Text = Convert.ToString(X);
                        ActualIntLbl.Text = Convert.ToString(X);
                        PrinAmtTxt.Enabled = false;

推荐答案

看看DateTime.Date

http://msdn.microsoft.com/en-us/library/system.datetime. date.aspx [^ ]

Have a look at DateTime.Date

http://msdn.microsoft.com/en-us/library/system.datetime.date.aspx[^]

// This would be date + time
DateTime now = DateTime.Now;

// This is just date
now.Date

还是总有ToShortDateString

http://msdn.microsoft.com/en-us/library/system.datetime. toshortdatestring.aspx [ ^ ]

Or there''s always ToShortDateString

http://msdn.microsoft.com/en-us/library/system.datetime.toshortdatestring.aspx[^]

您不能仅将日期转换为DateTime.那会是几月几号?您确定要使用默认的月份和年份吗?您可能会假设当前的月份和年份，对吗?

如果假设当前月份和年份，则可以执行以下操作.

You can not convert ONLY date to DateTime. What month and year would that be? Are you sure you want to use the default month and year? You may be assuming the current month and year, are you?

If you are assuming current month and year, you could do something like this.

DateTime RepayStartDate = DateTime.Now;
RepayStartDate .Month = Convert.ToInt32(StartDateTxt.Text);

将文本字符串转换为DateTime对象后，应确保两者包含相同的时间值.将每个中的时间设置为零将确保您的时间为整天.

When you have converted your text string to a DateTime object you should ensure that both contain the same time value. Setting the times in each to zero would ensure that your timespan will be a full number of days.
