我有一個用於選擇行的LS應用程序的域服務，並且該行中的許多字段都是datetime字段。我不斷收到LINQ到了日期時間轉換實體錯誤，當我試着做下面的代碼：在linq選擇期間將實體字段賦值日期
public IQueryable<riaProjectItem> FilterProjectItems(int? projID)
{
var FilteredProjectItems = _
from pi in this.Context.ProjectItems
where (pi.Project.Id == projID)
orderby pi.ItemCode ascending
select new riaProjectItem
{
// Note we turn the ID of the Internal Products to
// A negative number so we don't have duplicates
// with the External products
Id = pi.Id,
ItemCode = pi.ItemCode,
ItemName = pi.ItemName,
TechnicalStartDate = pi.TechnicalStartDate.GetValueOrDefault().Date,
TechnicalWeeks = Convert.ToDecimal(pi.TechnicalWeeks.ToString()),
TechnicalPercentComplete = Convert.ToDecimal(pi.TechnicalPercentComplete.ToString()),
EditingStartProjected = pi.EditingStartProjected.GetValueOrDefault().Date,
EditingStartActual = pi.EditingStartActual.GetValueOrDefault().Date,
EditingWordWeeks = Convert.ToDecimal(pi.EditingWordWeeks.ToString()),
EditingEditPercent = Convert.ToDecimal(pi.EditingEditPercent.ToString()),
EditingReview = Convert.ToDecimal(pi.EditingReview.ToString()),
ClientReviewStartProjected = pi.ClientReviewStartProjected.GetValueOrDefault().Date,
ClientReviewStartActual = pi.ClientReviewStartActual.GetValueOrDefault().Date,
TranslationPercent = Convert.ToDecimal(pi.TranslationPercent.ToString()),
ClientReview = Convert.ToDecimal(pi.ClientReview.ToString()),
FinalStartProjected = pi.FinalStartProjected.GetValueOrDefault().Date,
FinalStartActual = pi.FinalStartActual.GetValueOrDefault().Date,
FinalForm = Convert.ToDecimal(pi.FinalForm.ToString()),
FinalReview = Convert.ToDecimal(pi.FinalReview.ToString()),
CBTStartDateProjected = pi.CBTStartDateProjected.GetValueOrDefault().Date,
CBTStartDateActual = pi.CBTStartDateActual.GetValueOrDefault().Date,
CBTWeeks = Convert.ToDecimal(pi.CBTWeeks.ToString()),
CBTPercent = Convert.ToDecimal(pi.CBTPercent.ToString()),
DeliveryDate = pi.DeliveryDate.GetValueOrDefault().Date,
ActualDeliveryDate = pi.ActualDeliveryDate.GetValueOrDefault().Date,
Comments = pi.Comments
} ;
return FilteredProjectItems;
}
// Override the Count method in order for paging to work correctly
protected override int Count<T>(IQueryable<T> query)
{
return query.Count();
}
}
類riaProjectItem
public class riaProjectItem
{
[Key]
public int Id { get; set; }
public int ItemCode { get; set; }
public string ItemName { get; set; }
public DateTime TechnicalStartDate { get; set; }
public Decimal TechnicalWeeks { get; set; }
public decimal TechnicalPercentComplete { get; set; }
public DateTime EditingStartProjected { get; set; }
public DateTime EditingStartActual { get; set; }
public decimal EditingWordWeeks { get; set; }
public decimal EditingEditPercent { get; set; }
public decimal EditingReview { get; set; }
public DateTime ClientReviewStartProjected { get; set; }
public DateTime ClientReviewStartActual { get; set; }
public decimal TranslationPercent { get; set; }
public decimal ClientReview { get; set; }
public DateTime FinalStartProjected { get; set; }
public DateTime FinalStartActual { get; set; }
public decimal FinalForm { get; set; }
public decimal FinalReview { get; set; }
public DateTime CBTStartDateProjected { get; set; }
public DateTime CBTStartDateActual { get; set; }
public decimal CBTWeeks { get; set; }
public decimal CBTPercent { get; set; }
public DateTime DeliveryDate { get; set; }
public DateTime ActualDeliveryDate { get; set; }
public string Comments { get; set; }
}
如何分配日期到實體領域？
