有什么办法找出哪些对象引起的NullReferenceException？ [英] Is there any way to find out which object caused the NullReferenceException?

问题描述

有没有办法找出导致流入catch块从一个NullReferenceException控制对象的名字，这样我们就可以很容易地通过给予警告或日志记录为空对象调试？

Is there any way to find the object name that caused the control to flow into the catch block from a NullReferenceException, so that we can easily debug by giving an alert or logging the object that was null?

推荐答案

没有。结果
你只得到堆栈跟踪，包括行号。结果
这可以帮助你在简单的情况下是这样的：

No.
You only get the stack trace including line numbers.
This helps you in simple cases like this:

var result = myString.Trim();

但它并不像这样行帮助：

But it doesn't help in lines like this:

var result = myObj.Method1().Method2();
