c# - 在linux上使用mono运行VS编译的C#(串行连接)文件

Question

据我所知，应该可以使用 C# mono 在 Linux 上运行 Visual Studio 编译的 C# 文件。我使用 apt-get install mono-complete 安装了它，所以所有内容都应该包含在内

但是，我确实遇到了一些未处理的异常错误，我自己也不明白，我希望有人能够帮助我。我应该注意到，一切都在 Windows 机器上按预期工作，并且我已经补偿了端口等，因此它应该适合 Linux。

我的设置如下:

_serialPort = new SerialPort();
_serialPort.PortName = SetPortName(_serialPort.PortName);
_serialPort.BaudRate = 115200;
_serialPort.StopBits = StopBits.One;   
_serialPort.Parity = Parity.None;
_serialPort.DataBits = 8;
_serialPort.Handshake = 0;
_serialPort.ReadTimeout = 500; 
_serialPort.WriteTimeout = 500;
_serialPort.Open();

我得到的错误是:

If someone could help me out I would be very grateful

首先，您的 VS C# exe 很可能是使用 Windows 依赖项编译的，尤其是在谈论 USB 和串行端口等硬件时，平台之间存在大量差异。如果您有源代码，那么您可以尝试此线程 How to convert a .NET exe to native Win32 exe? 中建议的方法，编译代码而不编译原生部分。

如果您没有源代码并且只有 exe，则需要使用 wine 方法在 wine 中运行代码。关于如何设置linux串口设备和wine(windows COMXX设备)的对应关系可以引用下面的帖子http://ubuntuforums.org/showthread.php?t=1335098 。如果您使用的是最新的 Linux 发行版，则必须通过将用户添加到拨出组来允许用户访问 ttySXX 端口。
