Is it possible to initialize a Control's List<T> property in markup?

由 一世执手 提交于 2020-01-05 03:35:56
问题 Let's say we have the following: public enum RenderBehaviors { A, B, C, } public class MyControl : Control { public List<RenderBehaviors> Behaviors { get; set; } protected override void Render(HtmlTextWriter writer) { // output different markup based on behaviors that are set } } Is it possible to initialize the Behaviors property in the ASPX/ASCX markup? i.e.: <ns:MyControl runat="server" ID="ctl1" Behaviors="A,B,C" /> Subclassing is not an option in this case (the actual intent of the

问题 I am using Struts 2 and I created a simple application following a tutorial I found. I've created a <MyActionClass>-validation.xml file and I wonder how can I display the validation messages based on multiple languages? <field name="password"> <field-validator type="requiredstring"> <param name="trim">true</param> <message>You have to enter a password.</message> </field-validator> </field> Can I get the messages from a localized .properties file or do I have to use some other kind of

SpringBoot 实践-外部化配置优先级问题

由 对着背影说爱祢 提交于 2020-01-04 13:33:42
本文主要针对 spring.profiles.active 、 spring.config.location 以及 spring.config.additional-location 的作用机制及优先级问题进行实践对比。 本文案例工程已上传 github 仓库：https://github.com/glmapper/springboot-series-guides/tree/master/guides-properties spring.profiles.active 除了 application.properties 文件之外，profile-specific 配置也可以通过以下命名方式来定义:application-{profile}.properties。在没有使用 active 指定 profiles 的情况下，Environment 会指定一组默认的 profiles（默认情况下是[default])，换句话说就是，如果没有显示的激活 profiles 配置文件，则默认加载的是 application-default.properties 配置文件。 profile-specific 配置文件的属性与标准 application.properties 从相同的位置加载（一般是 classpath 下）；profile-specific 指定的 properties

How to name a property when the preferred name is also the name of the type [duplicate]

问题 This question already has answers here : Closed 9 years ago . Possible Duplicate: Giving a property the same name as its class In working on a solution where I was struggling to "add" properties to a sealed class, someone pointed out that my naming of a property with the same name as a type was asking for trouble. Here's a snippet of my code: class BackupFileInfo : IEquatable<BackupFileInfo> { public FileInfo FileInfo { get; set; } } I would have preferred to just inherit FileInfo , but I can

Dynamically adding a property to a class

由 落花浮王杯 提交于 2020-01-04 06:25:25
问题 This has been previously asked on Stack Overflow, but none of the answers seem to address exactly what I need to do. In my case, I want these dynamically-added properties to be a shortcut to store and read values from a database, so unfortunately it's not as easy as in this answer (where a lambda function was used) or this one (where values where stored in a dictionary): I must call other methods of the class. This is my attempt: import operator class Foo(object): def get_value(self, name): #

Representing a C# accessor property in a UML Class Diagram?

由 有些话、适合烂在心里 提交于 2020-01-04 05:39:16
问题 How does one represent a C# property (setter and getter accessors) in a UML Class diagram? Do you just write it as regular setter and getter methods? Or is there some other way of representing it? I'm interested in how accessors are represented in a class and interface in a UML Class diagram. 回答1: Some developers / analysts: (1) show properties as a very conceptual thing, and only show a single row per property. (2) Others, are more specific, and display 3 rows, the property, the "getter"

Why does PyCharm raise a warning when using @property here?

由 风流意气都作罢 提交于 2020-01-04 05:27:18
问题 In tutorials I have seen two types of instance attribute naming for the purpose of using @property. Here is code showing examples of both. They also seem to work differently. class A: def __init__(self, x): self.x = x @property def x(self): return self.__x @x.setter def x(self, x): if x > 1000: self.__x = 1000 else: self.__x = x # Instance attribute __x defined outside __init__ class B: def __init__(self, x): self._x = x @property def x(self): return self._x @x.setter def x(self, x): if x >

Do you use Data Members or Public Properties from within the Class itself?

由 家住魔仙堡 提交于 2020-01-04 04:44:06
问题 If I have a simple class setup like this: class MyClass { private string _myName = string.Empty; public string MyName { get { return _myName; } } public void DoSomething() { // Get the name... string name = string.Empty; name = _myName; // OR name = MyName; // ...and do something with it... } } Which should I use, the public property, or the data member? Obviously, in this example it doesn't make a difference, since they both just reference the same variable. But what about real world uses of
