Question

我已经四处寻找并且还没有真正找到问题的答案。

我正在尝试浏览文件以获取图像文件并使用其路径作为变量传递到我的qr函数，但是当使用文件对话框时它给了我这个

＆lt; _io.TextIOWrapper name ='C：/ Users / Elias / Desktop / New folder / IMG_2635.JPG'mode ='r'noding ='cp1252'＆gt;

而不是这个 C：/ Users / Elias / Desktop / New folder / IMG_2635.JPG

有没有办法更好地做到这一点？

您正在使用var smtc = _player.SystemMediaTransportControls; smtc.ButtonPressed += OnSMTCButtonPressed; smtc.IsEnabled = true; smtc.IsNextEnabled = true; smtc.IsRecordEnabled = true;。这会为您提供文件句柄。如果您只想要文件 name ，请使用filedialog.askopenfile()。
