如何通过 代码 关闭 MaterialDesign 的DialogHost 所显示的对话框

There are 3 ways to close a dialog in MDIX:

var dialogResult = await DialogHost.Show(myDialogControl, (sender, args) =>
{
    args.Session.Close(false);
});

or

DialogHost.CloseDialogCommand.Execute(null,null);

or

DialogHostInstance.IsOpen = false;
