C# 试图在我的WPF应用程序中从SQL获取数据

我正在尝试从我的SQL Server获取数据，但它不起作用

在我的应用程序中，我有两个项目，一个叫Db，一个叫App。 在数据库中，我使用dbml访问数据库，我可以找到用于插入、更新和删除的代码，但没有得到它

在我的xaml代码中，我有这个调用。

DbEstimatorDataContext conn = new DbEstimatorDataContext();

        List<Company_Control> Company_Controls = (from s in  conn.Company_Controls () 
                                                  select s).ToList();

<telerik:RadGridView.Columns>
                            <telerik:GridViewDataColumn  DataMemberBinding="{Binding Parent_Company}" Header="Parent Company"/>
                            <telerik:GridViewDataColumn  DataMemberBinding="{Binding Company_Id}"  Header="Company Id"/>
                            <telerik:GridViewDataColumn  DataMemberBinding="{Binding Company_Name}"  Header="Company Name"/>
                            <telerik:GridViewDataColumn  DataMemberBinding="{Binding Company_address_1}"  Header="Company Address 1"/>
                            <telerik:GridViewDataColumn  DataMemberBinding="{Binding Company_address_2}"  Header="Company Address 2"/>
                            <telerik:GridViewDataColumn  DataMemberBinding="{Binding Company_city}"  Header="Company City"/>
                            <telerik:GridViewDataColumn  DataMemberBinding="{Binding State}"  Header="State"/>
                            <telerik:GridViewDataColumn  DataMemberBinding="{Binding Postal_Code}"  Header="Postal Code"/>
                            <telerik:GridViewDataColumn  DataMemberBinding="{Binding Accounting_Code}"  Header="Accounting Code"/>
                            <telerik:GridViewDataColumn  DataMemberBinding="{Binding Active}"  Header="Active"/>
                            <telerik:GridViewDataColumn  DataMemberBinding="{Binding Control_Key}"  Header="Control Key"/>
                            <telerik:GridViewDataColumn  DataMemberBinding="{Binding Credit_Check}"  Header="Credit Check"/>
                            <telerik:GridViewDataColumn  DataMemberBinding="{Binding Customer_Account_Source}"  Header="Customer Account Source"/>
                            <telerik:GridViewDataColumn  DataMemberBinding="{Binding Customer_Account_Format}"  Header="Customer Account Format"/>
                            <telerik:GridViewDataColumn  DataMemberBinding="{Binding Overrun_Percent}"  Header="Overrun Percent"/>
                            <telerik:GridViewDataColumn  DataMemberBinding="{Binding Switches}"  Header="Switches"/>
                        </telerik:RadGridView.Columns>

DbEstimatorDataContext conn=new DbEstimatorDataContext（）；
列出公司控制=（来自conn.Company\U Controls（）中的s）
选择s.ToList（）；

我收到以下错误 *不可开票成员“dbBusiness.DbEstimatorDataContext.Company_Controls”不能像方法一样使用*

我在XAML中的绑定看起来像这样，但我甚至还没能尝试引用它。

DbEstimatorDataContext conn = new DbEstimatorDataContext();

        List<Company_Control> Company_Controls = (from s in  conn.Company_Controls () 
                                                  select s).ToList();

<telerik:RadGridView.Columns>
                            <telerik:GridViewDataColumn  DataMemberBinding="{Binding Parent_Company}" Header="Parent Company"/>
                            <telerik:GridViewDataColumn  DataMemberBinding="{Binding Company_Id}"  Header="Company Id"/>
                            <telerik:GridViewDataColumn  DataMemberBinding="{Binding Company_Name}"  Header="Company Name"/>
                            <telerik:GridViewDataColumn  DataMemberBinding="{Binding Company_address_1}"  Header="Company Address 1"/>
                            <telerik:GridViewDataColumn  DataMemberBinding="{Binding Company_address_2}"  Header="Company Address 2"/>
                            <telerik:GridViewDataColumn  DataMemberBinding="{Binding Company_city}"  Header="Company City"/>
                            <telerik:GridViewDataColumn  DataMemberBinding="{Binding State}"  Header="State"/>
                            <telerik:GridViewDataColumn  DataMemberBinding="{Binding Postal_Code}"  Header="Postal Code"/>
                            <telerik:GridViewDataColumn  DataMemberBinding="{Binding Accounting_Code}"  Header="Accounting Code"/>
                            <telerik:GridViewDataColumn  DataMemberBinding="{Binding Active}"  Header="Active"/>
                            <telerik:GridViewDataColumn  DataMemberBinding="{Binding Control_Key}"  Header="Control Key"/>

                            <telerik:GridViewDataColumn  DataMemberBinding="{Binding Overrun_Percent}"  Header="Overrun Percent"/>
                            <telerik:GridViewDataColumn  DataMemberBinding="{Binding Switches}"  Header="Switches"/>
                        </telerik:RadGridView.Columns>

get在哪里，应该是“select*from Company\u Control”？

错误指示您应该在conn.Company\u Controls之后删除（）-它是一个属性，而不是一个方法。

谢谢，我开始认为我必须创建一个存储过程来获取数据
