我正在用CustomControls制作一个WPF CustomControlLibrary,它继承了Label、TextBox等标准控件。当我试图制作另一个从TextBlock继承的CustomControl时,我会遇到奇怪的错误。CustomControl似乎无法从TextBlock继承。
但为什么呢?
提前感谢!
我刚刚创建了从TextBlock:继承的自定义控件
using System.Windows.Controls;
namespace WpfApplication1
{
public class CustomTextBlock : TextBlock
{
}
}
并在同一项目中使用:
<Window x:Class="WpfApplication1.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="clr-namespace:WpfApplication1">
<Grid>
<local:CustomTextBlock Text="Hello" />
</Grid>
</Window>
因此答案是:
您可以从TextBlock继承
但是,为了在xaml中使用它,您必须首先编译项目。你的代码中可能有其他错误,阻止了项目的编译,因此你可能也会遇到类似的错误
The type 'local:CustomTextBlock' was not found. Verify that you are not missing an assembly reference and that all referenced assemblies have been built
或simmilar错误:
The name "CustomTextBlock" does not exist in the namespace "clr-namespace:WpfApplication1".
一旦你修复了其他错误,这些错误也会消失。
