XAML编辑器只是一直显示:成员无法识别或不可访问
XAML编辑器只是一直显示:成员无法识别或不可访问
提问于 2016-01-28 23:11:57
我创建了一个UserControl:一个在左侧显示图标的TextBox。我的代码似乎可以工作，但下面的错误仍然显示，并使XAML编辑器将其标记为错误。
成员无法识别或无法访问。
我也没有在我的属性中得到自动补全，我想是因为这个错误吧？我对WPF UserControls不是很熟悉。
我已经清理并重新构建/重新启动了我的项目多次。这并没有什么帮助，XAML编辑器只是在每个自定义属性上不断地显示这个错误。
我使用的是.NET 4.6.1。

我复制了你的问题并找到了解决方案。
您需要在CustomBackgroundProperty中为PropertyMetadata添加一个默认值。
尝尝这个
public string CustomBackground {
get { return (string)GetValue(CustomBackgroundProperty); }
set { SetValue(CustomBackgroundProperty, value); }
}
public static readonly DependencyProperty CustomBackgroundProperty =
DependencyProperty.Register("CustomBackground", typeof(string),
typeof(IconTextBox),new PropertyMetadata(null));Stack Overflow用户

我遇到了这个问题。我最终不得不关闭visual studio并重新启动它。一旦我这样做了，XAML设计时编辑器就会再次工作。

错误显示在哪一行？我已经用vs2010测试过你的代码，它运行正常，没有任何错误。
