c＃hello world not compiling

问题描述：

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＃，但由于我有一个Mac，没有窗口，我无法下载Visual Studio Express等。我听说过单声道并安装了它，但指令很难跟踪，而且我也没有如果我没有下载任何东西，如果我把东西存储在错误的地方，或者是什么，但是我不能得到一个简单的Hello World来编译。c＃hello world not compiling

我下载了再装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

要测试安装，我也跟着在http://www.mono-project.com/Mono_Basics

为你好世界的说明，然后我得到了82错误！

下面是我在终端的bash窗口中键入：

这是我的hello.cs中文件包含：

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

我复制并粘贴正是在http://www.mono-project.com/Mono_Basics提供到TextEdit并将文件创建为.rtf，然后将扩展名更改为.cs

有人可以告诉我我已经完成（或未完成）创建混乱吗？谢谢。

奇怪，但通常我们用命名空间编写C＃，但这可能不是相关的... – 2012-07-24 06:30:23

也许.rtf是罪魁祸首 – V4Vendetta 2012-07-24 06:31:07

我复制并粘贴正是在http://www.mono-project.com/Mono_Basics提供到文本编辑和创建的文件为.rtf再变扩展.CS

是的，不这样做。将其创建为纯文本文件。 RTF不是纯文本。它可能看起来像在RTF查看器/编辑器中显示时显示为纯文本，但您所做的是本质上与在Word中创建文件相同，然后期望gmcs读取Word文档。

它必须是纯文本文件，其内容如示例所示。

打开终端，然后'猫> Hello.cs' – 2012-07-24 06:32:10

，我认为这就是问题所在：

as an .rtf then changed the extension to .cs

尝试编辑CS文件中的一些基本的文本编辑器。
