C＃WPF MenuStrip控制器

Question

我正在嘗試通過創建WindowsFormsHost並添加MenuStrip作為其子級，在C＃中使用WPF制作MenuBar。 請注意，我使用WindowsFormsHost Controller的屬性頁添加菜單和菜單項。

完成后，項目將成功構建並運行，但是在生成的“ xaml”文件中顯示了一些錯誤，並且設計人員沒有加載設計。

這是生成的XAML代碼

<Window
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:Forms="clr-namespace:System.Windows.Forms;assembly=System.Windows.Forms" x:Class="FrontEnd.AppMainWindow"
    Title="AppMainWindow" Height="351" Width="826">
<Grid>
    <WindowsFormsHost x:Name="menuStripHost" HorizontalAlignment="Left" Height="23" VerticalAlignment="Top" Width="818">
        <Forms:MenuStrip Visible="True" Name="appMainMenu">
            <Forms:MenuStrip.Items>
                <Forms:ToolStripMenuItem Text="File">
                    <Forms:ToolStripMenuItem.DropDownItems>
                        <Forms:ToolStripMenuItem ShortcutKeys="Ctrl+N" Text="New Project"/>
                        <Forms:ToolStripMenuItem ShortcutKeys="Ctrl+O" Text="Open Project"/>
                        <Forms:ToolStripMenuItem Text="Exit"/>
                    </Forms:ToolStripMenuItem.DropDownItems>
                </Forms:ToolStripMenuItem>
                <Forms:ToolStripMenuItem Text="View">
                    <Forms:ToolStripMenuItem.DropDownItems>
                        <Forms:ToolStripMenuItem Text="Configuration Window"/>
                    </Forms:ToolStripMenuItem.DropDownItems>
                </Forms:ToolStripMenuItem>
                <Forms:ToolStripMenuItem Text="Help">
                    <Forms:ToolStripMenuItem.DropDownItems>
                        <Forms:ToolStripMenuItem Text="User Manual"/>
                        <Forms:ToolStripMenuItem Text="Help"/>
                    </Forms:ToolStripMenuItem.DropDownItems>
                </Forms:ToolStripMenuItem>
            </Forms:MenuStrip.Items>
        </Forms:MenuStrip>
    </WindowsFormsHost>

</Grid></Window>

這是錯誤

錯誤2無法將指定的值分配給集合。 預期以下類型：“字符串”。

對於具有標簽“ Forms：ToolStripMenuItem”的所有行，都會出現相同的錯誤

更新：試圖刪除ShortcutKeys屬性，並且問題仍然存在（與上述相同的錯誤）。 這是修改后的代碼...

        </Forms:MenuStrip>

我認為在ToolStripMenuItems中，您正在為ShortcutKeys屬性分配一個字符串：ShortcutKeys =“ Ctrl + N” ...根據文檔，這應該是'Keys'類型。 https://msdn.microsoft.com/zh-cn/library/system.windows.forms.toolstripmenuitem.shortcutkeys%28v=vs.110%29.aspx?f=255&MSPPError=-2147217396
