需要帮助:从C ++迁移到C#.NET [英] Help Needed: migrating from C++ to C#.NET

问题描述

当前，我们有一个管理系统，它是一个基于主机的应用程序，用户可以从使用以下技术"开发的基于PC的前端进行访问.

Currently we have an administration system which Is a host-based application, accessible to users from a PC-Based Front-End Developed with Below Technologies.

• 平台包括:Windows XP/7，包括DB/2，MQ系列，Visual C ++，用于NT/XP的LANDP
• 热点:包括MVS，Shandi(MFS)，JCL，OO COBOL，DB/2，Easytrieve
• 前端层和中间层是C ++.

我的问题是

1.       如果将其从C ++迁移到C#.NET，它将如何受益
2.       我们可能面临的挑战
3.         关于性能哪个更好(C ++或C#.NET)

1.        How It’s Going to Benefit if we migrate it from C++ to C#.NET
2.        What we need to consider when we wanted to migrate from C++ to C#.NET,
3.        What Challenges we may FACE
4.        With Respect to Performance which one is Better (C++ or C#.NET)
5.        Where we need to start

或者您对此有何看法.

 请帮助我...

 Please Help me with this…

谢谢.

推荐答案

我假设您的代码当前是标准" C ++，而不是C ++/CLI.

I'm assuming that your code is currently 'standard' C++, and not C++/CLI.

1.对于大多数人来说，最大的好处是使用C ++以外的几乎任何语言(例如C#)进行编程要容易得多. C ++非常困难且令人无法原谅，更不用说当您得到某些东西时可怕的编译器消息了 错误的.  我要大步走出去，建议C ++程序员需要大约10年的经验来精通该语言，而对于C#则需要不到5年.

1. The biggest benefit is that for most people it's far easier to program in almost any language (such as C#) other than C++.  C++ is notoriously difficult and unforgiving, not to mention the horrible compiler messages when you get something wrong.  I'm going to go out on a limb and suggest that a C++ programmer needs about 10 years experience to master the language, while less than 5 years for C#.

2.通常，使用C ++编写多平台代码会更容易，但是从您的技术列表来看，这似乎并不是真正的问题，并且C#非常适合Windows环境.

2. Generally, it's easier to write multi-platform code with C++, but from your list of technologies it looks like that's not really an issue and C# is well-suited to a Windows environment.

3.代码转换并不容易-您可能必须手动重写很多代码.  然后，您应该愿意进行大量测试，以确保新代码具有相同的效果-希望您已经进行了大量的单元测试.

3. Code conversion is not easy - you may have to manually rewrite a lot of code.  Then you should be willing to do a *lot* of testing to ensure the new code has the same effect - hopefully you already have a ton of unit tests.

4.标准C ++可以使您编写性能更好的代码，但这需要您真正了解C ++并完美地完成所有工作-很少有C ++程序员足以做到这一点.  看到我的 在#1中发表评论.

4. Standard C++ has the potential to allow you to write better-performing code, but that requires that you really know C++ well and do everything perfectly - relatively few C++ programmers are good enough to do this.  See my comments in #1.

5.重新检查您为什么要迁移代码.  这不能掉以轻心.

5. Re-examine why you want to migrate the code.  It's not to be taken lightly.
