你应该经常使用它，我用它来区分私有字段和参数(因为我们的命名约定声明我们不为成员和参数名使用前缀(并且它们是基于在互联网上找到的信息，所以我认为这是一个最佳实践))

我也倾向于在任何地方使用它，只是为了确保我们正在处理的是实例成员。

我并不想这么说，但这并不重要。

认真对待。

看看那些重要的东西:你的项目，你的代码，你的工作，你的个人生活。它们中的任何一个都不会成功依赖于是否使用“this”关键字来限定对字段的访问。这个关键字不会帮助你按时发货。它不会减少bug，也不会对代码质量或可维护性产生明显的影响。它不会让你加薪，也不会让你在办公室花更少的时间。

It's really just a style issue. If you like "this", then use it. If you don't, then don't. If you need it to get correct semantics then use it. The truth is, every programmer has his own unique programing style. That style reflects that particular programmer's notions of what the "most aesthetically pleasing code" should look like. By definition, any other programmer who reads your code is going to have a different programing style. That means there is always going to be something you did that the other guy doesn't like, or would have done differently. At some point some guy is going to read your code and grumble about something.

I wouldn't fret over it. I would just make sure the code is as aesthetically pleasing as possible according to your own tastes. If you ask 10 programmers how to format code, you are going to get about 15 different opinions. A better thing to focus on is how the code is factored. Are things abstracted right? Did I pick meaningful names for things? Is there a lot of code duplication? Are there ways I can simplify stuff? Getting those things right, I think, will have the greatest positive impact on your project, your code, your job, and your life. Coincidentally, it will probably also cause the other guy to grumble the least. If your code works, is easy to read, and is well factored, the other guy isn't going to be scrutinizing how you initialize fields. He's just going to use your code, marvel at it's greatness, and then move on to something else.

除非万不得已，否则不要用this。

不必要的冗长是有惩罚的。您应该努力使代码的长度恰好与需要的长度相同，而不是更长。

就我个人而言，我在引用成员变量时总是尝试使用这个。它有助于澄清代码并使其更具可读性。即使没有歧义，第一次阅读我的代码的人也不知道这一点，但如果他们看到始终使用这个，他们就会知道他们是否在查看成员变量。
