感谢您阅读我的问题。我对 C# 和 mono 非常非常陌生。我想为 .Net 学习 C#，但由于我有 Mac 并且没有 Windows，我无法下载 Visual Studio Express 等。我听说过 mono 并安装了它，但这些说明对我来说很难遵循，而且不是确定我是否还没有下载所有内容，是否将内容存储在错误的位置，或者什么，但我无法编译一个简单的 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)

    GC:            Included Boehm (with typed GC)

为了测试安装，我按照http://www.mono-project.com/Mono_Basics上的 Hello World 说明进行操作

然后我得到了82个错误！

这是我在终端 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提供的内容复制并粘贴到 TextEdit 中，并将文件创建为 .rtf，然后将扩展名更改为 .cs

有人能告诉我我做了什么（或没做什么）来制造这个烂摊子吗？谢谢。

是的，不要那样做。将其创建为纯文本文件。RTF 不是纯文本。在 RTF 查看器/编辑器中显示时，它可能看起来像纯文本，但您所做的基本上与在 Word 中创建文件，然后期望gmcs读取 Word 文档相同。

它必须是纯文本文件，其内容如示例中所示。

我认为这是问题所在：

as an .rtf then changed the extension to .cs

尝试在一些基本的文本编辑器中编辑 cs 文件。
