  "contentMarkdown": "# C#调用Shell命令\n\n> 创建时间：2020/10/23 12:10\n\n使用C#在Windows系统上调用命令行，在MacOS上调用bash，笔者在实现时遇到了很多坑，记录下来。\n以下代码亲测直接可用。在某些版本中，使用某个方法可能会出问题，选一个使用即可。\n\n## 类Unix系统上调用bash\n\n通过StartInfo.Arguments参数，只执行一行命令。\n\n```xml\npublic class UsingEnum<T> where T : System.Enum { }\npublic class UsingDelegate<T> where T : System.Delegate { }\npublic class Multicaster<T> where T : System.MulticastDelegate { }\n\n```\n\n通过重定向标准输入输出流，一行一行执行命令\n\n```xml\npublic class UsingEnum<T> where T : System.Enum { }\npublic class UsingDelegate<T> where T : System.Delegate { }\npublic class Multicaster<T> where T : System.MulticastDelegate { }\n\n```\n\n标准输入输出的方式也可以写一行，在行末尾加exit 命令，退出。\n如果不执行exit命令，调用StandardOutput.ReadToEnd，会由于无法读到终止符而阻塞进程。\n\n```xml\npublic class UsingEnum<T> where T : System.Enum { }\npublic class UsingDelegate<T> where T : System.Delegate { }\npublic class Multicaster<T> where T : System.MulticastDelegate { }\n\n```\n\n## windows系统调用CMD\n\n理论上与UNIX-like系统调用shell命令方式相同\n以下为一行命令执行完的方法。由于在CMD中ReadToEnd会读出多余信息，这里提供一个CMDOutputFilter函数过滤多余的信息。\n\n```xml\npublic class UsingEnum<T> where T : System.Enum { }\npublic class UsingDelegate<T> where T : System.Delegate { }\npublic class Multicaster<T> where T : System.MulticastDelegate { }\n\n```\n\n以luacheck工具为例，测试以上函数\n\n```csharp\nclass MyClass<T, U>\n    where T : class\n    where U : struct\n{ }\n\n```\n"
