为项目提供了一种完整的感觉。例如，我将有所有相关的项目文件在单一视图。 提供了更高的代码生产力，如 语法高亮显示 程序集引用 智能感知 数据库和相关UI文件的集中视图。 调试特性

最后，它帮助我更快地编写代码，而不是在记事本或写字板上。这是我更喜欢IDE的一个很好的理由。

我喜欢IDE，因为它能在我的指尖提供很多功能。编辑/编译/项目中文件的可见性是我在IDE中所看重的一切。我现在使用Visual Studio，但在以前我使用slikedit，并发现它使我的开发过程比我不使用它时更流畅。

我从相反的方向来回答这个问题。我从小就在Makefile+Emacs的环境中编程。从我最早的DOS编译器，微软的Quick C，我有一个IDE自动化的事情。我在Visual c++ 6.0上工作了很多年，当我毕业到Enterprise Java时，我使用Borland JBuilder，然后决定使用Eclipse，这对我来说已经变得非常高效。

Throughout my initial self-teaching, college, and now professional career, I have come to learn that any major software development done solely within the IDE becomes counterproductive. I say this because most IDE's wants you to work in their peculiar I-control-how-the-world-works style. You have to slice and dice your projects along their lines. You have manage your project builds using their odd dialog boxes. Most IDE's manage complex build dependencies between projects poorly, and dependencies can be difficult to get working 100%. I have been in situations where IDE's would not produce a working build of my code unless I did a Clean/Rebuild All. Finally, there's rarely a clean way to move your software out of development and into other environments like QA or Production from an IDE. It's usually a clicky fest to get all your deployment units built, or you've got some awkward tool that the IDE vendor gives you to bundle stuff up. But again, that tool usually demands that your project and build structure absolutely conforms to their rules - and sometimes that just won't work for your projects' requirements.

我了解到，要与团队一起进行大规模开发，如果我们使用IDE开发代码，并使用手动编写的命令行脚本进行所有构建，那么我们可以获得最高的效率。(我们喜欢用Apache Ant进行Java开发。)我们发现在IDE中运行我们的脚本对于复杂的构建来说只是一个点击或者自动化的噩梦，用alt+tab到一个shell并在那里运行脚本要容易得多(而且破坏性更小)。

Manual builds requires us to miss out on some of the niceties in the modern IDE like background compilation, but what we gain is much more critical: clean and easy builds that can live in multiple environments. The "one click build" all those agile guys talk about? We have it. Our build scripts can be directly invoked by continuous integration systems as well. Having builds managed through continuous integration allows us to more formally stage and migrate your code deployments to different environments, and lets us know almost immediately when someone checks in bad code that breaks the build or unit tests.

In truth, my taking the role of build away from the IDE hasn't hurt us too badly. The intellisense and refactoring tools in Eclipse are still completely useful and valid - the background compilation simply serves to support those tools. And, Eclipse's peculiar slicing of projects has served as a very nice way to mentally break down our problem sets in a way everyone can understand (still a tad bit verbose for my tastes though). I think one of the most important things about Eclipse is the excellent SCM integrations, that's what makes team development so enjoyable. We use Subversion+Eclipse, and that has been very productive and very easy to train our people to become experts at.

我使用它的主要原因是当代码超过100个文件时。

虽然ctags可以完成这项工作，但一些ide有一种非常好的方法来轻松快速地浏览文件。

当你有很多工作要做的时候，这样可以节省时间。

使用ide的一个很好的理由是，它们是生产现代软件的公认方式。如果您不使用，那么您可能会使用“老式”的东西，如vi和emacs。这可能会导致人们得出结论——可能是错误的——你被困在自己的方式中，无法适应新的工作方式。在软件开发这样的行业——创意可能在短短几个月内就会过时——这是一种危险的状态。这可能会严重损害你未来的工作前景。
