WPF InitializeComponent无法识别

Question

WPF完全不熟悉，并且遵循Microsoft演练的要求，将XML替换为以下内容：

Index  12/13/2018  12/14/2018  12/15/2018  12/16/2018  12/17/2018
   0   Carol       Peter       Alice       Peter       John
   1   John        Carol       null        Alice       Peter
   2   null        John        null        null        null
   3   null        Alice       null        null        null

所以我替换了它，但是现在如果我转到文件<Window x:Class="Window1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="Northwind Orders" Height="335" Width="425" Name="OrdersWindow" Loaded="Window1_Loaded"> <Grid Name="orderItemsGrid"> <Grid.ColumnDefinitions> <ColumnDefinition Width="258*"/> <ColumnDefinition Width="161*"/> </Grid.ColumnDefinitions> <ComboBox DisplayMemberPath="OrderID" ItemsSource="{Binding}" IsSynchronizedWithCurrentItem="true" Height="23" Margin="92,12,37.703,0" Name="comboBoxOrder" VerticalAlignment="Top"/> <DataGrid ItemsSource="{Binding Path=Order_Details}" CanUserAddRows="False" CanUserDeleteRows="False" Name="orderItemsDataGrid" Margin="34,46,34.4,49.6" AutoGenerateColumns="False" Grid.ColumnSpan="2"> <DataGrid.Columns> <DataGridTextColumn Header="Product" Binding="{Binding ProductID, Mode=OneWay}" /> <DataGridTextColumn Header="Quantity" Binding="{Binding Quantity, Mode=TwoWay}" /> <DataGridTextColumn Header="Price" Binding="{Binding UnitPrice, Mode=TwoWay}" /> <DataGridTextColumn Header="Discount" Binding="{Binding Discount, Mode=TwoWay}" /> </DataGrid.Columns> </DataGrid> <Label Height="28" Margin="34,12,0,0" Name="orderLabel" VerticalAlignment="Top" HorizontalAlignment="Left" Width="65">Order:</Label> <StackPanel Name="Buttons" Orientation="Horizontal" HorizontalAlignment="Right" Height="40" Margin="0,261,22.4,4.6" Grid.ColumnSpan="2"> <Button Height="23" HorizontalAlignment="Right" Margin="0,0,12,12" Name="buttonSave" VerticalAlignment="Bottom" Width="75" Click="buttonSaveChanges_Click">Save Changes </Button> <Button Height="23" Margin="0,0,12,12" Name="buttonClose" VerticalAlignment="Bottom" Width="75" Click="buttonClose_Click">Close</Button> </StackPanel> </Grid> </Window> ，则MainWindow.xmal.cs的代码将突出显示为不存在。

这是为什么，我该如何纠正？

您必须将XAML中的x:Class="Window1"与类class MainWindow后面的代码进行匹配。

将XAML从x:Class="Window1"更改为x:Class="NorthwindClient.MainWindow"
