wpf 设计元素不同，所以它没有见过设计

Question

我打开了一个项目解决方案，其中 xaml & cs 文件位于不同的位置。而且它不显示该 xaml 文件的设计。xaml 文件以标签开头，就像

abc 意味着它不是窗口也不是用户控件......

Answer 1

它不能只是 abc，因为这会产生编译错误。

它可以是一个自定义控件（从另一个控件或框架元素派生的控件），前缀为 命名空间 像这样：

<local:MyControl>
    <Grid>
       <!-- etc. -->
    </Grid>
</local:MyControl>

命名空间（local:）通常定义在文件的顶部，并指向定义控件的程序集。 （从技术上讲，如果您还在 MyControl 标记上设置 xmlns="your-namespace-uri" ，则可以跳过命名空间前缀，但这会使 < ;Grid> - 其下方的标记非法，除非获得正确的命名空间。）
