我有一个用VB编写的解决方案(有一个C#项目),我正在visualstudio 2015中调试。当我命中断点并将鼠标悬停在对象上时,代码会崩溃,并出现以下错误:
The program '[18348] MRS.ProductSupport.UI.vshost.exe' has exited with code -2147023895 (0x800703e9).
我没有找到任何关于这个错误的相关信息,也没有解释为什么会发生这种情况。有一些网站说这是一个IIS问题。我的代码确实使用了Web服务,但这不是从我正在调试的代码部分调用的。
奇怪的是,我可以查看对象的属性而不会崩溃。例如,我有以下对象:
item.FeatureID
我可以在上面徘徊
FeatureID
得到一个值。如果我停留在
item
这以前是一个间歇性的问题,但我的系统已更新到Windows10,现在看来,任何对象都会导致代码崩溃,当我查看它。
只是澄清一下,如果没有断点,代码就会运行。我不是在处理空对象。我确实尝试进入Properties->Debug,并选中“Enable native code debugging”,但没有成功。我的目标是.NET4。
更新:
在我的一次测试过程中,visualstudio崩溃了。当我重新打开它时,我可以访问该对象并查看所有属性。我使用了精确的断点,并像以前一样检查了精确的对象。但是,下一次我运行时,代码再次崩溃。我退出了visualstudio并重新启动,但这次问题没有得到解决。
我确实从一个单独的VS实例附加了一个调试进程,并且能够捕获这些错误:

附加信息
我对正在查看的对象(名为“item”)运行了一个GetType,然后对其进行了扩展,出现了三个可见的异常。老实说,我不知道这是否是问题的原因,但我想我会分享一下,以防它有帮助:
三个都跑了
DirectCast((item.GetType()), System.RuntimeType).DeclaringMethod
三个人都收到了一封信
System.InvalidOperationException
.
