在 Dynamics AX 中 无论版本是2009还是2012或者D365，总是会遇到下面这两个报错：
- Object ‘CLRObject’ could not be created
- ClrObject static method invocation error
而且系统给出的日志实在是太简短了，让人摸不着头脑。不过一般出现这两个问题都是在AX中处理 .net 相关的 dll 或者在调用 web service、WCF。那么剩下的问题就是我们该怎么样得知在调用 .net 框架的时候究竟出了什么问题呢，一旦知道了具体原因就好办了。
好，那我们通过一个 Job 演示一下吧：

//Necessary if executed on the AOS
new InteropPermission(InteropKind::ClrInterop).assert();
try
{
//This will cause an exception
System.Int32::Parse("abc");
}
catch(Exception::CLRError)
{
//Access the last CLR Exception
info(CLRInterop::getLastException().ToString());
//See AifUtil::getClrErrorMessage for another alternative
//how to parse the Exception object
}
//Revert CAS back to normal
CodeAccessPermission::revertAssert();
}

执行上面代码我们可以得到如下信息：

从这一段就可以看出到底是哪里出问题了。
