Answer 1

当应用程序尝试创建BitmapImage时，似乎发生了此异常，是否可能是您的系统阻止或锁定对加载图像所需的特定文件的访问？

Answer 2

WIC，您在堆栈跟踪顶部看到的是WPF的基础映像库。它是一个用C ++编写的COM组件。对于使用AccessViolation进行炸弹的非托管代码，不是不常见的。您可以通过启用非托管代码调试并启用Microsoft Symbol Server来从堆栈跟踪中获取更多信息。

然而，在这个问题上施加任何影响的可能性都不大。你可以调整的唯一旋钮是图像本身，它可能会以一种使代码炸弹的方式腐败。并确保在计算机上安装了Service Pack 1。除此之外，您还需要Microsoft支持人员的帮助。他们需要一个崩溃程序的小模块和造成麻烦的图像。

非常感谢 - 非常有帮助。打开非托管代码调试导致我的问题是“这表明内存在其他地方已损坏”。由于我没有太多记忆，我知道它一定是被引用的外部dll之一。事实证明，ICSharpCode.TextEditor.dll是问题的根源，并更新到它的最新版本修复它!!!
