Hi,


I am getting an issue while converting an object into DateTime. I am getting the following problem :

The getStartDateOfEvent is my stored procedure.

Business Logic :

Object exist = events.getStartDateOfEvent(EventID, OrganizerID);
DateTime dt1 = (DateTime)exist;

The value i get while debugging in exist is : 7/9/2012 12:34:45 PM
and in dt1 i get the value 1/1/0001 12:00:00 AM

So what will be the exact solution. I have tried in many ways but not getting any solution.

推荐答案

做到这一点的方法是

The way to do it would be

string MyString = exist.tostring();
DateTime dt1 = DateTime.ParseExact(MyString, "yyyy-MM-dd HH:mm tt",
                                  null);

如果内部接收到的对象的数据类型为datetime，则将通过显式分配将其转换为Datetime.

看起来，在内部它不是日期时间类型.您需要对其进行显式转换.
此处:

If the object recieved was of datatype datetime internally then it will be converted into Datetime by explicit assignment.

Looks like, internally it is not of datetime type. You need to convert it explicitly.
Here:

Object exist = events.getStartDateOfEvent(EventID, OrganizerID);
DateTime dt1 = Convert.ToDateTime(exist);
