Question

感谢您阅读我的问题。我对C＃和单声道非常非常新。我想为.Net学习C＃，但由于我有一台Mac而且没有窗户，我无法下载Visual Studio Express等。我听说过单声道并安装了它，但说明书很难让我遵循，而不是确定如果我没有下载所有内容，如果我将内容存储在错误的位置，或者是什么，但我无法编译简单的Hello World。

我下载然后安装了MonoFramework-MDK-2.10.9_11.macos10.xamarin.x86

My-MacBook-Pro:~$ gmcs --version
Mono C# compiler version 2.10.9.0

My-MacBook-Pro:~$ mono --version
Mono JIT compiler version 2.10.9 (tarball Mon May  7 20:25:51 EDT 2012)

为了测试安装，我按照http://www.mono-project.com/Mono_Basics

的Hello World说明进行操作

然后我收到了82个错误！

这是我在terminal-bash窗口中输入的内容：

这是我的hello.cs文件包含的内容：

using System;
 
public class HelloWorld
{
    static public void Main ()
    {
        Console.WriteLine ("Hello Mono World");
    }
 
}

我将http://www.mono-project.com/Mono_Basics提供的内容完全复制并粘贴到TextEdit中，然后将文件创建为.rtf，然后将扩展名更改为.cs

有人能告诉我我做了什么（或没做过）创造这个混乱？谢谢。

Answer 1

我将http://www.mono-project.com/Mono_Basics提供的内容完全复制并粘贴到TextEdit中，然后将文件创建为.rtf，然后将扩展名更改为.cs

是的，不要那样做。将其创建为纯文本文件。 RTF不是纯文本。当在RTF查看器/编辑器中显示时，它可能看起来像一样纯文本，但你所做的是本质上与在Word中创建文件相同，然后期待{{ 1}}阅读Word文档。

它必须是纯文本文件，其内容如示例所示。

Answer 2

我认为这是问题所在：

as an .rtf then changed the extension to .cs

尝试在某些基本文本编辑器中编辑cs文件。

c＃hello world没有编译
