将 VB6 应用程序迁移到 .NET 平台几乎就像重写，无论是 VB.NET 还是 C#。与 .NET 平台相比，您是否认为在 Java 平台上需要付出更多的努力，因为它无论如何都是重写的？请分享您的想法!
最佳答案
没有冒犯，但你错了。移植到 .Net 通常比重写远容易。
这是来自 Microsoft UK 的官方建议:
Performing a complete rewrite to .NET is far more costly and difficult to do well [than converting] ... we would only recommend this approach for a small number of situations.
来自blog post由咨询重写的 Microsoft 人员提供:
Many companies I worked with in the early days of .NET looked first at rewriting driven in part by a strong desire to improve the underlying architecture and code structures at the same time as they moved to .NET. Unfortunately many of those projects ran into difficulty and several were never completed. The problem they were trying to solve was too large
我建议按顺序执行以下两个步骤。
- 写下迁移或重写的原因。 它会带来什么好处？好处可能只是让开发团队开心 - 这甚至可能是一个足够好的理由，我不知道。确保你知道，并且你的经理/用户同意。
- 查看 Microsoft UK advice用screencast解释 .Net 迁移的 5 个基本选项。决定哪个最好。它可能正在重写，但请睁大眼睛进入它。
回答您的实际问题:在 .Net 或 Java 中完全重写会更容易吗？那mainly depends on你的团队最了解哪一个。它还在一定程度上取决于应用程序是否与 COM 交互，就像 SLaks 所说的那样。
