WPF ListView-列标题不是作为属性，而是作为Dictionary的键(Dictionary是ListViewI

Question

我想在我的WPF应用程序中制作一个MatrixControl。首先，它从ListView开始，并在模型中定义"MatrixLine"。ListView ItemsSource是ObservableCollection。我有一个简单完整的模型，显示了我的目标，还有一张我对创建的模型的预期结果的图片。

我遇到了一个问题，即如何添加Dictionary的"MatrixLine"属性类型，在ListView中添加[Keys]作为列标题，在te ListView上添加[Values](布尔值(作为符号"x"。(图片及以下结果(

我的模型的预期结果我在ViewModel构造函数中创建模型的结果

我认为这是我的解决方案。我还不完全理解这个解决方案，但我必须尝试一下。
