WPF內置命令

Question

我正在查找內置WPF命令的完整列表。

到目前爲止我發現的最好名單是here，但它沒有列出所有的命令。

一些可有可無具有細節將是：

• 控制/與所述命令的支持組件（例如，TextBox支持編輯命令，如粘貼，複製，剪切，重做，和撤消） ;

• 默認鍵手勢和UI文本（可從MSDN Library中提取）。

Answer 1

這是很容易顯示在所有加載的程序集的所有命令的完整列表：

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(); 
    } 

隨着PresentationFramework的加載，我得到這個答案的底部列表，你會看到它是絕對完整的。這樣

 let commandType = prop.PropertyType 

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

那麼你的選擇可能是這樣：

如果您還希望看到命令類型（例如RoutedUIComand）和手勢，你可以添加這對LINQ

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

以編程方式查找哪些控件對給定命令執行某些操作也是可能的。基本上，這樣的事情應該工作（沒試過，但是這會給你的想法）：

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(); 

其中ConvertILToString很可能是這樣的：

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

結果可以使用任何方式你喜歡，例如他們可以使用一個ItemsControl顯示：

<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 ... 

另外，您可以輸出文本或XML格式的數據或將其添加到數據庫。另外請注意，如果您更喜歡使用列表命令，則可以使用外部的命令迭代轉換此第二個查詢。

上面的代碼會給你確切的事實，不會撒謊，因爲它正在看着.NET Framework本身。

這個列表是完整的。

如果在主題中有任何額外的手勢，可以通過加載主題資源字典並對其進行一些LINQ來輕鬆提取它們。查詢很簡單：只需搜索<InputGesture>。 更新：我不認爲主題中有任何手勢，因爲默認手勢是從資源中加載的。所以這部分可能不是必需的。

Answer 2

退房的ApplicationCommands，ComponentCommands和NavigationCommands類。這些類都包含表示各種標準路由命令的靜態屬性，您可以在自己的應用程序中使用這些命令，並與框架內的內部控件進行交互。
