C# 让datagrid使用反射创建具有未知类型的列

我有两个模型

Case1ViewModel : ViewModelBase, ITestInterface
Case2ViewModel : ViewModelBase, ITestInterface

它们都继承自ITestInterface，该接口为空

然后我有一个

ObservableCollection<ITestInterface>

XAML

_嗯
_取消

本例中的结果是，我获得了对应字符串，但不会显示来自批发商DialogTradeItemViewModel的所有其他属性，如果我从界面中删除对应项，则不会显示任何内容

另一个示例（右键单击以显示全尺寸）

答案以替换结束

public ObservableCollection<ITestInterface> Transactions

显然，这迫使编译器使用反射来找出要显示的内容，如果我使用该接口，它也会将该
