Question

SqlException: The conversion of a datetime2 data type to a datetime data type resulted in an out-of-range value.

my code is like this:

        using (var contxt = new realtydbEntities())
        {
            var status = GetStatus();

            var repIssue = new RepairIssue()
            {
                CreaterId = AuthorId,
                RepairItemDesc = this.txtDescription.Text,
                CreateDate = DateTime.Now,//here's the problem
                RepairIssueStatu = status
            };

            contxt.AddObject("RepairIssues", repIssue);
            contxt.SaveChanges();
        }

the CreateDate property mapping to a column which type is smalldatetime.

how to make this code run?

Answer 1

The root of your problem is that the C# DateTime object is “bigger” than SQL’s smalldatetime type. Here’s a good overview of the differences: http://karaszi.com/the-ultimate-guide-to-the-datetime-datatypes

So really your options are:

1. Change the column type from smalldatetime to datetime (or datetime2)
2. Instead of using EF, construct your own SQL Command (and you can use SqlDateTime)
