C\# is a general purpose object-oriented [programming language][] developed at Microsoft and released in 2002. It is similar to Java in its syntax. The purpose of C\# is to precisely define a series of operations that a computer can perform to accomplish a task.

C＃是由Microsoft开发并于2002年发布的一种通用的面向对象的[编程语言][programming language] 。它的语法类似于Java。 C＃的目的是精确定义计算机可以执行以完成任务的一系列操作。

Most C\# operations involve manipulating numbers and text, but anything that the computer can physically do can be programmed in C\#. Computers have no intelligence—they have to be told exactly what to do, and their actions are defined by the programming language you use. Once programmed, they can repeat the steps as many times as needed at high speed. Modern PCs are so fast they can count to a billion in seconds.

大多数C＃操作涉及操纵数字和文本，但是计算机可以实际执行的任何操作都可以使用C＃进行编程。 计算机没有智能，必须告诉他们确切的操作方法，并且它们的操作由您使用的编程语言定义。 编程后，它们可以根据需要以高速重复多次。 现代PC如此之快，以至于数秒之内就可以达到十亿。

## C＃程序可以做什么？ **(** What Can a C\# Program Do? **)** ##

Typical programming tasks include putting data into a [database][] or pulling it out, displaying high-speed graphics in a game or video, controlling electronic devices attached to the PC and playing music or sound effects. You can even use it to write software to generate music or help you compose.

典型的编程任务包括将数据放入[数据库][database]或将其提取出来，在游戏或视频中显示高速图形，控制连接到PC的电子设备以及播放音乐或音效。 您甚至可以使用它来编写软件来生成音乐或帮助您作曲。

Some developers believe that C\# is too slow for games because it is [interpreted][] rather than compiled. However the .NET Framework compiles the interpreted code the first time it runs.

一些开发人员认为C＃对于游戏来说太慢了，因为它是[解释][interpreted]而不是编译的。 但是，.NET Framework首次运行时会编译解释后的代码。

## C＃是最好的编程语言吗？ **(** Is C\# the Best Programming Language? **)** ##

C\# is a highly ranked program language. Many computer languages are written for a specific purpose, but C\# is a general purpose language with features to make programs more robust.

C＃是一种高级程序语言。 许多计算机语言是为特定目的而编写的，但是C＃是具有使程序更强大的功能的通用语言。

Unlike C++ and to a lesser extent Java, the screen handling in C\# is excellent on both desktops and the web. In this role, C\# overtook languages such as Visual Basic and Delphi.

与C ++和Java(在较小程度上)不同，C＃的屏幕处理在台式机和Web上均非常出色。 在这个角色中，C＃取代了诸如Visual Basic和Delphi之类的语言。

## 哪些计算机可以运行C＃？ **(** Which Computers Can Run C\#? **)** ##

Any PC that can run the [.NET Framework ][.NET Framework]can run the C\# programming language. Linux supports C\# using the Mono C\# compiler.

任何可以运行[.NET Framework的][.NET Framework] PC都可以运行C＃编程语言。 Linux使用Mono C＃编译器支持C＃。

## 我如何开始使用C＃？ **(** How Do I Get Started With C\#? **)** ##

You need a C\# compiler. There are a number of commercial and free ones available. The professional version of Visual Studio can compile C\# code. Mono is a free and open-source C\# compiler.

您需要一个C＃编译器。 有许多商业和免费的。 专业版的Visual Studio可以编译C＃代码。 Mono是一个免费的开源C＃编译器。

## 我如何开始编写C＃应用程序？ **(** How Do I Begin Writing C\# Applications? **)** ##

C\# is written using a text editor. You write a computer program as a series of instructions (called [statements][]) in a notation that looks a little like mathematical formulas.

C＃是使用文本编辑器编写的。 您将计算机程序编写为一系列指令(称为[语句][statements] )，其符号看起来有点像数学公式。

This is saved as a [text file][] and then compiled and linked to generate machine code which you then can run. Most applications you use on a computer were written and compiled like this, many of them in C\#.

该[文件][text file]将另存为[文本文件][text file] ，然后进行编译和链接以生成可以运行的机器代码。 您在计算机上使用的大多数应用程序都是这样编写和编译的，其中许多都是用C＃编写的。

## 有大量的C＃开源代码吗？ **(** Is There Plenty of C\# Open Source Code? **)** ##

Not as much as in Java, C or C++ but it is starting to become popular. Unlike commercial applications, where the source code is owned by a business and never made available, open source code can be viewed and used by anyone. It's an excellent way to learn coding techniques.

虽然不像Java，C或C ++那样多，但是它开始流行起来。 与商业应用程序不同，在商业应用程序中，源代码归企业所有，并且从未公开使用，任何人都可以查看和使用开放源代码。 这是学习编码技术的绝佳方法。

## C＃程序员的就业市场 **(** The Job Market for C\# Programmers **)** ##

There are plenty of C\# jobs out there, and C\# has the backing of Microsoft, so is likely to be around for a while.

有大量的C＃作业，并且C＃在Microsoft的支持下，因此可能会出现一段时间。

You could write your own games, but you'd need to be artistic or need an artist friend because you also need music and sound effects. Perhaps you'd prefer a career as a business software developer creating business applications or as a software engineer.

您可以编写自己的游戏，但由于需要音乐和声音效果，因此需要具有艺术性或需要艺术家朋友。 也许您更喜欢从事创建业务应用程序的业务软件开发人员或软件工程师的职业。
