Question

我是一名开发人员，试图将旧的ASP.Net StoreFront网站更新到足以让我在本地计算机上运行。但是，我得到了这个问题：

[AccessViolationException: Attempted to read or write protected memory. This is often an indication that other memory is corrupt.]

我试过了：

禁用JIT
禁用编译器优化
强制x86平台目标
注释掉所有已加载的程序集
我已更新为ASP.Net 4.5.2

该网站不仅在我的计算机上损坏，而且在生产网站上也出现了相同的错误。

我正在处理的网站是专有的，我受到保密协议的约束，因此我无法发布代码段。有没有人有任何建议？

编辑：我可以访问源代码。如果我运行该项目，它会在Global.asax.cs文件中运行方法时抛出错误。如果我对此进行评论，它只会抛出相同的错误而没有目标。

编辑：1。代码中没有找到DllImport或unsafe。

我正在使用IISExpress，我可以附加到IISExpress进程

[AccessViolationException：尝试读取或写入受保护的内存。这通常表明其他内存已损坏。 c：\ Dev \ Web \ App_Code \ Global.asax.cs：222中的AspDotNetStorefront.Global.InitializeComponent（）] c：\ Dev \ Web \ App_Code \ Global.asax.cs中的AspDotNetStorefront.Global..ctor（）：35 ASP.global_asax..ctor（）在c：\ AppData \ Local \ Temp \ Temporary ASP.NET Files \ root \ 47c1f925 \ 38c0005 \ App_global.asax.inuh90ct.0.cs：0

如果我将当前被指向的函数调用注释为源，这是我得到的错误：

解决方案：ASPDNSF 7.0与ASP.Net＆gt;不兼容2.0

他们都指向asp.net 3.5 sp1和.net 3.5 sp1，这是导致尝试阅读的错误.....错误

Answer 2

正如@JonSaunders在评论中暗示的那样，这似乎是由于不正确地调用本机代码造成的。这将是第一个检查的地方 - 在解决方案中寻找潜在问题点的[DllImport和unsafe。我已经看到这个错误弹出，例如，使用非线程安全的非托管库。
更重要的是，将调试器附加到w3wp.exe IIS工作进程，在构造函数的第一个语句处设置断点，访问有问题的页面，然后开始单步调试。使用此选项可以找出导致访问冲突的呼叫或呼叫。

要将调试程序附加到w3wp，您必须确保以管理员身份运行Visual Studio，并且必须在部署网站的计算机上运行它至。这个过程应该让您更好地了解导致AccessViolation的原因，并允许更好的研究/提问。
