Question

VS中的xaml编辑器一直在给我＆＃34;无效标记＆＃34; MESSG。

我添加了一个类CustomCommands.cs，在xaml等中添加了Windows.CommandBindings，但VS中的输出错误是：

[失败]无法找到文件＆c; \ users \ bart \ documents \ visual studio 2015 \项目\ examentest200 \ examentest200 \ CustomCommands.cs＆＃39;

然而，如果我在资源管理器中检查文件，那就在那里。

提前致谢

＆＃34; CustomCommands.cs＆＃34;

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Input;

namespace examentest200
{
public static class CustomCommands
{
    public static readonly RoutedUICommand Change = new RoutedUICommand
 (
           "Change",
        "Change",
        typeof(CustomCommands),
        new InputGestureCollection()
        {
             new KeyGesture(Key.F6, ModifierKeys.Alt)
        }
    );

    }
}

Answer 1

如果您收到此错误：

[失败]无法找到文件'c：\ users \ bart \ documents \ visual studio 2015 \项目\ examentest200 \ examentest200 \ CustomCommands.cs'。

...它可能表明CustomCommands.cs尚未编译。在项目构建之前，XAML设计师不会看到您的课程。
