容易接触非专用物体
原标题:Cross-thread access to non-ui object in wpf

I m在WPF评估中利用背景工作者存在一些问题。 这里的情况:

我试图做两件事。 首先扫描一些图像,然后在扫描图像上使用条码识别。 我把扫描图像作为比特马锡物体清单,应当提供给我的背景工作者阅读。

在有些争执之后,似乎多数解决办法都是与主线上的自成分子沟通的,因为我所发现的任何解决办法都没有为我工作。 我先尝试使用代表和发送人,但徒劳无益。

我需要“比图斯”与它们共同制定比图,这是对条码确认的投入。

感谢

在计生联中,所有<代码> 异构体(而不仅仅是信标成分)只能从产生这些内容的深层中获取。 <代码>BitmapSource 继承(间接继承) 目标,因此遵循这一规则。 但是,如果冻结<>/>,也可从<代码>上继承。

因此,在您的<代码>BitmapSource启动后,您可打电话Freeze,并可从其他校对查阅。
