Question

I have an MVC3 app. I make a call to a database, get my data in a dataset and store it in my class. Heres how im storing my data from the dataset

                var dt = ds.Tables[0];
                var i = 0;
                foreach (DataRow dr in dt.Rows)
                {
                    wt = new WorkTasksDto
                             {
                                 Notes = dr["Notes"].ToString(),
                                 DueDate = Convert.ToDateTime(dr["DueDate"])
                 }

This is my class member:

          [DataMember]
            public DateTime? DueDate
            { get; set; }

The field DueDate that comes back from sql server is null and thats fine but when i try to store it in my DueDate field in my class i get the following error:

 "Object cannot be cast from DBNull to other types"

How do fix this error? Thanks

Answer 1

Take a look at DataRow.IsNull

DueDate = dr.IsNull("DueDate")? (DateTime?)null : (DateTime?)dr["DueDate"]
