Reduces the loss caused by NullReferenceException

Reduces the loss caused by NullReferenceException

I wrote a blog by ILoveSleep a few days ago. "I criticized many bloggers, but I don't think I should say something ugly to a blog. After all, ILoveSleep just shared his thoughts, if you have any questions, let's say that he is also very modest in his reply to everyone. He must be a person who can accept others' opinions. Today, I also want to say that NullReferenceException can be sprayed on everyone. I am not afraid of this person.

I don't have ILoveSleep so much patience to explain to you. At the same time, the Code is very simple, so I directly paste the code.
