WPF 内置命令

Question

我正在寻找内置 WPF 命令的完整列表。

目前我找到的最好的列表是here，但它并没有列出所有命令。

一些不错的细节是：

• 支持命令的控件/组件（例如，TextBox 支持粘贴、复制、剪切、重做和撤消等编辑命令）；

• 默认按键手势和 UI 文本（可从 MSDN Library 提取）。

Answer 1

在所有加载的程序集中显示所有命令的完整列表很容易：

  public string[] GetAllCommands()
  {
    return (
      from assembly in AppDomain.CurrentDomain.GetAssemblies()
      from type in assembly.GetTypes()
      from prop in type.GetProperties()
      where
        typeof(ICommand).IsAssignableFrom(prop.PropertyType) &&
        prop.GetAccessors()[0].IsStatic
      orderby type.Name, prop.Name
      select type.Name + "." + prop.Name
    ).ToArray();
  }

PresentationFramework 加载后，我得到了这个答案底部的列表，你会看到它是绝对完整的。

如果您还想查看命令类型（例如 RoutedUIComand）和手势，可以将其添加到 LINQ：

      let commandType = prop.PropertyType

      let gestures =
        typeof(UIElement).IsAssignableFrom(commandType) ?
          ((UIElement)prop.GetValue(null)).InputGestures :
        null

那么你的选择可能是这样的：

      select type.Name + "." + prop.Name + " " + commandType.Name + " " + gestures

以编程方式找出哪些控件对给定命令执行某些操作也是可能的。基本上这样的事情应该可以工作（没有尝试过，但这会给你这个想法）：

var allCommands = (
  from assembly in AppDomain.CurrentDomain.GetAssemblies()
  from type in assembly.GetTypes()
  from prop in type.GetProperties()
  where
    typeof(ICommand).IsAssignableFrom(prop.PropertyType) &&
    prop.GetAccessors()[0].IsStatic
  orderby type.Name, prop.Name
  select new
  {
    typeName = type.Name,
    propName = prop.Name,
    displayAs = type.Name + "." + prop.Name,
  }
).ToArray();

var classesReferencingCommand = (
  from assembly in AppDomain.CurrentDomain.GetAssemblies()
  from type in assembly.GetTypes()
  from method in type.GetMethods()
  let methodBodyString = ConvertILToString(method.MethodBody.GetILAsByteArray())
  let info = new
  {
    typeName = type.FullName,
    referencedCommands =
      from cmd in allCommands
      where
        methodBodyString.Contains(cmd.typeName) &&
        methodBodyString.Contains(cmd.propName)
      select cmd
  }
  where info.commands.Any()
  select info
).ToArray();

ConvertILToString 可能是这样的：

static string ConvertILToString(byte[] bytes)
{
  return new string(bytes.Where(b => b!=0).Select(b => (char)b).ToArray());
}

结果可以以任何你喜欢的方式使用，例如它们可以使用 ItemsControl 显示：

<ItemsControl Source="{Binding classesReferencingCommand}">
  <ItemsControl.ItemTemplate>
    <DataTemplate>
      <StackPanel>
        <TextBox Text="{Binding typeName}" FontWeight="Bold">
        <ItemsControl Source="{Binding referencedCommands}" Margin="10 0 0 0">
          <ItemsControl.ItemTemplate>
            <DataTemplate>
                <TextBox Text="{Binding displayAs}" />
      ... close all tags ...

或者，您可以以文本或 XML 格式输出数据或将其添加到数据库中。另请注意，如果您更喜欢按命令列出，则可以使用外部的命令迭代来翻转第二个查询。

上面的代码将为您提供准确的事实并且不会说谎，因为它正在查看 NET Framework 本身。

如果主题中有任何其他手势，可以通过加载主题资源字典并对其执行一些 LINQ 轻松提取它们。查询很简单：只需搜索<InputGesture>。 更新：我认为主题中没有任何手势，因为默认手势是从资源加载的。所以这部分可能没有必要。

Answer 2

查看ApplicationCommands、ComponentCommands 和NavigationCommands 类。这些类都包含代表各种标准路由命令的静态属性，您可以在自己的应用程序中使用它们并与框架内的内部控件进行交互。
