问题 This question is an opposite of How to find types that are direct descendants of a base class? If this is the inheritance hierarchy I have, class Base { } class Derived1 : Base { } class Derived1A : Derived1 { } class Derived1B : Derived1 { } class Derived2 : Base { } I need a mechanism to find all the sub types of Base class in a particular assembly which are at the end of the inheritance tree. In other words, SubTypesOf(typeof(Base)) should give me -> { Derived1A, Derived1B, Derived2 } 回答1:

问题 I need to get all types of an assembly that inherits some base class but only the first descendants. For instance if I have: class Base { } class FirstClass : Base { } class SecondClass : FirstClass { } Now var directOnes = assembly.GetTypes().Where(t => t.IsSubclassOf(typeof(Base))); should return only FirstClass and not SecondClass . Is there a way to find out? 回答1: Instead of IsSubclassOf() you can use Type.BaseType e.g. var directOnes = assembly.GetTypes().Where(t => t.BaseType == (typeof

问题 I write a customized item layout for a listview. The layout has many widgets and some will have its own clicklistener. When I click the row, sometimes the listview' s onListItemClick work, but sometimes not. After I spent some time searching, I find a way, setting android:descendantFocusability="blocksDescendants" in the layout' s root. It works, but only one textview cannot work,(the clickable, fucusable attr have been tried). In the list' s adapter, I set the textview' s onClickListener, it

问题 Suppose I have the following XML file: <?xml version="1.0" encoding="UTF-8"?> <response> <project> <ixGroup>105</ixGroup> <sGroup>Place Group</sGroup> </project> <project> ... And I use the following code to extract the distinct <ixGroup> and <sGroup> text values from it: XDocument doc = XDocument.Load(@"C:\temp\xmlParse2.xml"); var projects = (from project in doc.Descendants("project") select new { id = project.Element("ixGroup").Value, name = project.Element("sGroup").Value }).Distinct();

问题 This question already has answers here : CSS “outline” different behavior behavior on Webkit & Gecko (2 answers) Closed last year . I am working with css outline property, and I found that it is working differently between Chrome and Firefox if descendant elements are outside. in Chrome, outline is only for itself range, even though any descendant elements are outside of itself area. in Firefox, outline is all range including all descendant elements. <div style=" margin: 100px; width: 100px;

问题 I have a situation where an element contains n clickable handles and n revealable elements: <div class="revealer"> <div class="hotspot"> <a class="handle" href="javascript:;">A</a> <div class="reveal"> <p>Content A.</p> </div> <div class="reveal"> <p>Content B.</p> </div> </div> </div> When I click 'handle', it shows both 'reveal' elements. This works fine. This chunk of code is dropped into a given document wherever the creator wants. Including... inside another <div class="reveal"></div>

问题 XElement.Descendants () method accepts name of element to be find. But it is case-sensitive is there any way to make it case-insensitive 回答1: You can use this: element.Descendants() .Where(x => string.Compare(x.Name, filter, StringComparison.OrdinalIgnoreCase) == 0); 回答2: This way worked for me.. XElement selectedElement = doc.Descendants().Where(x => String.Equals((string)x.Attribute("name"), filtertext, StringComparison.InvariantCultureIgnoreCase)).FirstOrDefault(); 来源： https:/

问题 Since Python 3.5 you can use Generics and other interesting stuff described in PEP-0484. I tried that and here's a code I have: from typing import TypeVar, Generic, Optional ... _T = TypeVar('T') _S = TypeVar('S') class Pool(Generic[_S, _T]): def __init__(self) -> None: self.pool = dict() ... getters and setters here... This code works perfectly and does what is expected. Then I decided to extend this class to make some additional work. That's how I did that: class PoolEx(Pool[_S, _T]):
