migrating to C# from Java_问答_开发者_运维开发者技术经验分享

I saw a thread similar to this, but the reason I'm asking this is because my situation is different.

I've been a tester (automated and manual) but I have a good Java programming knowledge although I haven't worked as a programmer.

My company is considering to move me to a C# programming role. Will it be hard for me to learn C# without an开发者_开发问答y prior experience in programming?

Thanks

My 2 cents is that once you understand core concepts of programming you can move to any programming language. Try and remain as language agnostic as possible.

Specific to your question, you should be able to make the transition without much effort at all.

C# and Java are so similar you won't have any problems at all. That said, there are a few differences, this page does a pretty thorough job of demonstrating them.

One thing it doesn't mention is LINQ, which is definitely different as we're seeing the two languages start to diverge a bit more.

I have difficulties combining the statements "I have good Java programming knowledge" with "without any prior experience in programming". How can you have good Java programming knowledge without any experience in programming?

That said, if you are an able Java programmer, moving to C# should not be very difficult.

Speaking strictly about syntax, C# pretty similar to Java so you should have no problems there (at least it will feel familiar at first).

Moving to C# will not be a problem at all.

Since you already know Java, you'll find many concepts in C# easy to understand.

In fact, it's always a great thing to learn and work on multiple languages throughout your career, especially if they cover different paradigms.

I've had 4 programming jobs in my life, and for 3 of them I had no experience at all with the language before starting the job. The 1 for which I did have experience ended up being a complete disaster of a workplace.

If there's any correlation between how well you know a specific programming language before taking a job, and how you can get/do a job at a place where they use that language, I have yet to see it in my 10+ years. I'd say it's probably one of the least important factors contributing to your success.

Unless you plan to work at a company for a very short period of time, you'll learn many new things, and probably new languages, while working there. Whether you happen to know the one they're using now is like how tall Michael Jordan was when he was in high school: after a few dozen/hundred/thousand hours of practice, completely irrelevant.

Without any industry experience in Java it won't be easy to work in... Java. What I mean is you will have exactly the same difficulties in C# as you would have in Java. The language change won't be the problem -the big difference will be working with real world requirements and practices.

Don't take me wrong, I don't mean you will have problems: you'll just learn a lot of new things. If you have a solid "conceptual" base switching from Java to C# will be easy, I did the same pretty much effortless.

Read a good book (for ex. Troelson's Pro C#) and you'll quickly pick up the most important differences. Then with time you'll learn the other stuff that is really different from Java (for ex. WPF, Linq, etc.).

In conclusion, don't be afraid and go for it!

C# should be trivial to learn if you know Java. The differences at the programming level are largely syntactic for the most part.

The difficulty (and this is the same with Java) is the language is just an enabler for a large number of libraries and technologies. So you could have no trouble picking up C# but you might hit a brick wall learning WPF because there is no analog in Java. etc. Or you might be trying to write ASP.NET but you have never learned JSP / Spring in Java so have nothing to relate to.

The best strategy is start small, get familiar with the constructs and then try to implement something useful. e.g. in WPF, you could write a simple Twitter client using webservices. In ASP.NET you might write a simple blog app hooked up to database app.

Once you get the basics and assuming you follow best practice, it should be easy enough to expand outwards.

If you have programming knowledge skills it would be not very difficult to move into c#. In my experience coming from PHP I suggest you the following steps,

Books:

1- C# 4.0 in a Nutshell The Definitive Reference

2- Apress.Pro.ASP.NET.MVC.Framework

Tutorials:

1- check the website http://www.asp.net and probably the best thing could be to move directly into MVC

2- check the nerddinner tutorial http://nerddinnerbook.s3.amazonaws.com/Part1.htm in order to get in knowledge of how this work.

3- Download Nerddinner code http://nerddinner.codeplex.com/

4- use entity framework instead of linq based on MS election for the future

5- Download some starter-kits from http://www.asp.net/mvc/samples/mvc-music-store to check the way it work.

Hope it helps. brgds,
