用我的實體框架填充我的文本框

Question

是否可以通過這種方式填充我的文本框？ 在選擇「無法隱式轉換類型system.Linq.Querable」時收到錯誤

基本上我試圖讓所有的數據庫，然後使用此連接來填充我的文本框在Web窗體上的其餘部分。

任何幫助或指針非常讚賞。

private void Loadorder() 
     { 
      using (tyrescannerdatabaseEntities dbcontext = new tyrescannerdatabaseEntities()) 

       query = (from Orders in dbcontext.Orders 

         join customer in dbcontext.Customers on Orders.CustomerID equals customer.CustomerID 

         join link_orderproduct in dbcontext.Link_OrderProduct on Orders.OrderID equals link_orderproduct.OrderID 

         join product in dbcontext.Products on link_orderproduct.ProductID equals product.ProductID 

         join garage in dbcontext.Garages on link_orderproduct.GarageID equals garage.GarageID 

         where Orders.OrderID == orderId.Value 

         select new DataMode 
         { 
         OrderID = Orders.OrderID, 
         Name = customer.Name 
         }; 


    private void SetControlsWithRecord() 
    { 
     txtOrderID.Text = query.OrderID.ToString(); 
     txtCustomer.Text = query.Customer.Name.ToString(); 
    } 

class DataMode 
{ 
    public int OrderID { get; set; } 
    public string Name { get; set; } 
    public string ContactNo { get; set; } 
    public string Registration { get; set; } 
    public string Brand { get; set; } 
    public string TyreModel { get; set; } 
    public decimal Width { get; set; } 
    public string Profile { get; set; } 
    public string Diamete { get; set; } 
    public string Speed { get; set; } 
    public string FittingDate { get; set; } 
    public decimal ProductUnitSalePrice { get; set; } 
    public string ProductQuantity { get; set; } 
    public string TotalProductSaleCost { get; set; } 
    public string MOT { get; set; } 
    public string AirConRecharge { get; set; } 
    public string WheelTracking { get; set; } 
    public string MOTS { get; set; } 

}

query = (from Orders in dbcontext.Orders 

        join customer in dbcontext.Customers on Orders.CustomerID equals customer.CustomerID 

        join link_orderproduct in dbcontext.Link_OrderProduct on Orders.OrderID equals link_orderproduct.OrderID 

        join product in dbcontext.Products on link_orderproduct.ProductID equals product.ProductID 

        join garage in dbcontext.Garages on link_orderproduct.GarageID equals garage.GarageID 

        where Orders.OrderID == orderId.Value 

        select new DataMode 
        { 
        OrderID = Orders.OrderID, 
        Name = customer.Name 
        }).ToList(); 

在查詢的末尾添加此ToList()。從這裏

txtOrderID.Text = query.OrderID.ToString(); 
    txtCustomer.Text = query.Customer.Name.ToString();
