C＃.net和Visual Basic.net有什么区别？

I have a small experience in VB.net and I would like to learn C#.net

我在VB.net有一点经验,我想学习C#.net

What are the differences between VB.net and C#.net?

VB.net和C#.net之间有什么区别?

Is there any difference in performance between these two?

这两者之间的表现有什么不同吗?

Apart from the syntactical differences, are there any major changes that I have to keep in mind?

除了语法上的差异之外,我还要记住哪些重大变化吗?

The Language Features section of the Wikipedia article offers a good overview. Performance is essentially equivalent in almost every aspect, from what I understand.

*文章的语言功能部分提供了一个很好的概述。从我的理解,几乎在每个方面,性能基本上是等同的。

#2

Performance is equivalent if you write equivalent code, but VB.NET has constructs that are in there for "backward compatibility" which should NEVER be used. C# doesn't have some of these things. I'm thinking specifically of:

如果你编写等效的代码,性能是相同的,但VB.NET的构造在那里是为了“向后兼容”,永远不应该使用。 C#没有这些东西。我特意想到:

Functions which are in the Microsoft.VisualBasic namespace which are members of other standard .NET classes like Trim(). The .NET classes are often faster.

Microsoft.VisualBasic命名空间中的函数,它们是Trim()等其他标准.NET类的成员。 .NET类通常更快。
Redim and Redim Preserve. Never to be used in .NET, but there they are in VB.

Redim和Redim Preserve。永远不要在.NET中使用,但它们在VB中。
On Error ... instead of exceptions. Yuck!

On Error ...而不是异常。呸!
Late binding (sometimes derisively called "Option Slow"). Not a good idea in a non-dynamic .NET language from a performance perspective.

后期绑定(有时被嘲弄地称为“选项慢”)。从性能角度来看,在非动态.NET语言中不是一个好主意。

VB is also missing things like automatic properties which makes it pretty undesirable for me. Not a performance issue, but worth keeping in mind.

VB也缺少像自动属性这样的东西,这对我来说非常不利。不是性能问题,但值得记住。

The first thing to know about learning C# is that it is not pronounced "C#.net", it is just C#. Microsoft tacked on ".NET" to VB, because there was a previous version of VB that didn't work on the .NET Framework. C# was created specifically with the .NET Framework in mind, so the ".net" is implied and unnecessary. Also as a side note putting "C#.NET" on your resume really tips off a knowledgeable manager to your skill level, or lack there of, regarding C#.

学习C#的第一件事是它不是发音为“C#.net”,它只是C#。微软将“.NET”加入VB,因为有一个以前版本的VB无法在.NET Framework上运行。 C#是专门为.NET Framework创建的,因此“.net”是隐含的,不必要的。另外,作为一个侧面说明,在你的简历中加入“C#.NET”真的会让一位知识渊博的经理知道你的技能水平,或者缺乏关于C#的技能水平。

Also this Wikipedia article is really good for showing the pros and cons as well as the differences between C# and VB.NET at a high level.

此*文章也非常适合在高级别上展示C#和VB.NET之间的优缺点以及差异。

In spite of differences as mentioned at http://support.microsoft.com/kb/308470 both C# and VB.Net are first class citizens of .Net world

尽管在http://support.microsoft.com/kb/308470中提到了差异,但C#和VB.Net都是.Net世界的一等公民

Although there are differences between Visual Basic .NET and Visual C# .NET, both are first-class programming languages that are based on the Microsoft .NET Framework, and they are equally powerful. Visual Basic .NET is a true object-oriented programming language that includes new and improved features such as inheritance, polymorphism, interfaces, and overloading. Both Visual Basic .NET and Visual C# .NET use the common language runtime. There are almost no performance issues between Visual Basic .NET and Visual C# .NET. Visual C# .NET may have a few more "power" features such as handling unmanaged code, and Visual Basic .NET may be skewed a little toward ease of use by providing features such as late binding. However, the differences between Visual Basic .NET and Visual C# .NET are very small compared to what they were in earlier versions.

虽然Visual Basic .NET和Visual C#.NET之间存在差异,但它们都是基于Microsoft .NET Framework的一流编程语言,并且它们同样强大。 Visual Basic .NET是一种真正的面向对象的编程语言,包括新的和改进的功能,如继承,多态,接口和重载。 Visual Basic .NET和Visual C#.NET都使用公共语言运行库。 Visual Basic .NET和Visual C#.NET之间几乎没有性能问题。 Visual C#.NET可能具有一些“强大”功能,例如处理非托管代码,而Visual Basic .NET可能会因为提供后端绑定等功能而略微偏向易用性。但是,与早期版本相比,Visual Basic .NET和Visual C#.NET之间的差异非常小。

No matter which language you select based on your personal preference and past experience, both languages are powerful developer tools and first-class programming languages that share the common language runtime in the .NET Framework.

无论您根据个人偏好和过去的经验选择哪种语言,这两种语言都是强大的开发人员工具和一流的编程语言,它们共享.NET Framework中的公共语言运行库。
