将标签值绑定到值 [英] Binding a label value to a value

问题描述

我是WPF的新手。我有app.config的值。我想将标签绑定到此值。

< StackPanel Margin =   10 VerticalAlignment =   Top >  
< DockPanel VerticalAlignment =   Center Margin =   10 >  
< Label DockPanel.Dock =   Left FontWeight =  粗体目标=   {Binding}>连接到服务器：< /  标签 >  
 < /   DockPanel  >  
 

说

  var   value  =系统.Configuration.ConfigurationManager.AppSettings [  Key] 
 .ToString（）;  //   1.1.1.1  

我是什么想要的是标签内容成为：

连接到服务器：1.1.1.1

解决方案

我称之为 CBS（强制性结合综合症）。解决方案是：

 labelKey.Content =  value ; 
  //  我甚至要解释原因吗？ 

当然，您需要在标签声明的XAML行中添加属性 Name =labelKey：< Label Name =labelKey... /> 。

绑定的真正目的是不同的。你可能想读一下这个主题。

我们有一个轶事流传着，其中一个国家有着名的辛辣，辛辣的美食：

一位旅行者在这种辛辣的美食方面遇到了麻烦，几乎无法容忍这么多辣椒。有一天，他坐在一家餐馆里，想着我能订购什么才能避免得到这么多辣椒？。他得到了一个叫做服务员的想法：



- 请，我想要煮鸡蛋。是的，只需煮沸，带壳;将全蛋放入贝壳中。



厨房在一两个小时内没有生产任何东西;人们开始担心。



- 需要这么长时间？



- 外出厨师是与所有人员进行头脑风暴：如何在这些鸡蛋中注入辣椒。

如果你想煮鸡蛋，只需将它们煮沸。

I am pretty new to WPF. I have a value from app.config. I want to binding a label to this value.

<StackPanel Margin="10" VerticalAlignment="Top">
       <DockPanel VerticalAlignment="Center" Margin="10">
           <Label DockPanel.Dock="Left" FontWeight="Bold" Target="{Binding}">Connect to Server:</Label>
       </DockPanel>

Say

var value = System.Configuration.ConfigurationManager.AppSettings["Key"]
               .ToString(); //1.1.1.1

What I want is the label content become:
Connect to Server: 1.1.1.1

解决方案

I call it "CBS" (Compulsory Binding Syndrome). The solution is:

labelKey.Content = value;
// Do I even have to explain why?

Of course, you need to add the attribute Name="labelKey" in XAML line with label declaration: <Label Name="labelKey" ... />.

The real purposes of binding are different. You may want to read on the topic.

We had an anecdote circulating, about one of the countries with notoriously spicy, peppery cuisine:

One traveler had trouble with this peppery cuisine, barely able to tolerate so much pepper. One day, he was sitting in a restaurant, thinking "What can I order to avoid getting so much pepper?". He got an idea an called a waiter:

"— Please, I want boiled eggs. Yes, just boiled, unshelled; serve the whole eggs, in the shells."

The kitchen did not produce anything for an hour or two; people started to worry.

"— What takes so long?"

"— Out chef is brainstorming with all the personnel: how to inject pepper in those eggs."

If you want boiled eggs, just boil them.
