lua - Lua: What's the difference between null and nil?

Question

I'm developing a plugin for Oxide 2. I've been learning from other plugins and I've noticed that some of them use null instead of nil. For example:

if args[1] == null then

Oxide 2 is written in C#, so I assume that null is defined in C# or in Lua Interface.

Is there any difference between them?

Update: I've somewhere read that it can be used for check, if MySQL column is NULL. Is that true?

Answer 1

nil是 Lua 语言中的一个值。

null是一个变量名。它包含什么价值？您可以轻松检查。我们不可以。如果结果是nil，那么 usingnull是没有意义的，可能是某人在 C# 和 Lua 代码之间切换上下文时犯的错误，因为未定义的变量将评估为nil.
