鑄造字符串UITestControl

爲了保持簡潔，我可以這樣做：鑄造字符串UITestControl

UIRvWindow AppWin = new UIRvWindow(); 

UITestControl path = new UITestControl(); 

path = AppWin.UnderlyingClass1.UnderLyingClass2; 

IEnumerable<WpfButton> collection = path.GetChildren().OfType<WpfButton>(); 

foreach(WpfButton button in collection) 
{ 
    System.Diagnostics.Trace.WriteLine(button.FriendlyName + " - " + button.DisplayText + " - " + button.Name + " - " + button.AutomationId); 
}

這工作得很好，但我希望能夠做到這一點：

UIRvWindow AppWin = new UIRvWindow(); 

UITestControl path = new UITestControl(); 

string x = "AppWin.UnderlyingClass1.UnderLyingClass2"; 

path = x; 

IEnumerable<WpfButton> collection = path.GetChildren().OfType<WpfButton>(); 

foreach(WpfButton button in collection) 
{ 
    System.Diagnostics.Trace.WriteLine(button.FriendlyName + " - " + button.DisplayText + " - " + button.Name + " - " + button.AutomationId); 
}

基本上，我有一個字符串列表，我想通過一個接一個地運行它們。有沒有辦法做到這一點？

你可能想標記這裏使用的語言 – pcnate

發佈示例代碼：AppWin.UnderlyingClass1.UnderLyingClass2'會有幫助。嘗試加載反射？ –

反射是一種實現動態調用的方式。假設你的類型名稱作爲字符串列表，那麼你可以做一些類似以下內容：如果所有的類都從具有它的虛擬GetChildren()方法的基類繼承

List<string> classes = new List<string> { "WindowsFormsApplication1.MyClass1", "WindowsFormsApplication1.MyClass2" }; 
foreach (var typeName in classes) 
{ 
    Type type = Type.GetType(typeName); 
    var instance = Activator.CreateInstance(type); 

    var result = (type.GetMethod("GetChildren").Invoke(instance, null) as IEnumerable<object>).OfType<WpfButton>(); 

}

，那麼你就可以減少一點如下反思：

foreach (var typeName in classes) 
{ 
    Type type = Type.GetType(typeName); 
    var instance = Activator.CreateInstance(type); 

    IEnumerable<WpfButton> myButtons = null; 
    if(instance is MyBase) //MyBase is base class having virtual GetChildren() and this base class is derived by MyClass1, MyClass2... 
    { 
      myButtons = (instance as MyBase).GetChildren().OfType<WpfButton>(); 
    } 
}

PS反射可能有性能問題，如果你打算使用過的種類太多，請謹慎和適當的設計目標使用它。希望這對你有所幫助...
