在控制台应用程序中，防止转义命令行参数中特殊序列的最佳方法是什么？

Question

I wrote this console app that reads a sequence of command line arguments and does something with them. 我编写了这个控制台应用程序，它读取一系列命令行参数并对其进行处理。

The problem is that if the user enters something like: 问题是，如果用户输入如下内容：

 --folder "C:\my folder\" --username john

the args String array of the Main function will have 2 elements rather than 4: Main函数的args String数组将包含2个元素，而不是4个：

1st element: "--folder"
2nd element: "C:\my folder\" --username john"

(the \\" sequence is escaped as a double quote.) （\\“序列以双引号转义。）

Since not using quotes would result in 5 elements... 由于不使用引号将导致5个元素...

--folder C:\my folder\ --username john

1st element: --folder
2nd element: C:\my
3rd element: folder\
4th element: --username
5th element: john

... what's the best way to get around this problem? ...解决这个问题的最佳方法是什么？

This is a consequence of the weird command line parsing rules on Windows. 这是Windows上奇怪的命令行解析规则的结果。 See here http://msdn.microsoft.com/en-us/library/windows/desktop/17w5ykft(v=vs.85).aspx . 请参阅http://msdn.microsoft.com/zh-CN/library/windows/desktop/17w5ykft(v=vs.85).aspx 。 The command line should actually be: --folder "C:\\my folder\\\\" --username john 命令行实际上应该是：-- --folder "C:\\my folder\\\\" --username john

This is a user input error. 这是用户输入错误。 You shouldn't try to correct it code; 您不应该尝试更正它的代码。 just fail gracefully. 只是优雅地失败。
