取消Date一词：

Take off the word "Date":

customerLoanRecord.CreatedOn = DateTime.Now;

DateTime对象的Date属性删除所有时间信息！

The Date property of a DateTime object removes all time information!

customerLoanRecord.CreatedOn = DateTime.Now.Date;

customerLoanRecord.CreatedOn = DateTime.Now.Date;

这应该是：

This should be:

customerLoanRecord.CreatedOn = DateTime.Now;

（假设 customerLoanRecord.CreatedOn 类型是日期时间 ）

将CreatedOn声明为属性，然后检查。

Declare CreatedOn as a property and then check.

private DateTime _CreatedOn = new DateTime();
public DateTime CreatedOn
{
     get
     {
         _CreatedOn = DateTime.Now;
         return _CreatedOn;
     }
     set
     {
         _CreatedOn = value;
     }
}
