标签和文本块之间的区别 [英] Difference between Label and TextBlock

问题描述

根据 与 Microsoft 合作开发 Windows 应用程序.NET 4 70-511 培训套件

Label 控件和 TextBlock 控件之间有什么区别，因为它们都是内容控件并且只显示文本?

What is the difference between the Label control and TextBlock control since both are content controls and just displaying text?

推荐答案

TextBlock 不是控件

即使 TextBlock 位于 System.Windows.Controls 命名空间中，它也不是控件.它直接派生自 FrameworkElement.另一方面，标签派生自 ContentControl.这意味着 Label 可以:

TextBlock is not a control

Even though TextBlock lives in the System.Windows.Controls namespace, it is not a control. It derives directly from FrameworkElement. Label, on the other hand, derives from ContentControl. This means that Label can:

1. 获得一个自定义控件模板(通过 Template 属性).
2. 显示除字符串以外的数据(通过 Content 属性).
3. 将 DataTemplate 应用到其内容(通过 ContentTemplate 属性).

4. 做任何 ContentControl 可以做而 FrameworkElement 做不到的事情.

1. Be given a custom control template (via the Template property).
2. Display data other than just a string (via the Content property).
3. Apply a DataTemplate to its content (via the ContentTemplate property).

4. Do whatever else a ContentControl can do that a FrameworkElement cannot.

• Label文字在禁用时变灰
