使用包含换行符的字符串参数启动外部程序

Question

From a .Net WinForms C# application I need to invoke another program (which is also a .Net WinForms C# application if that makes any difference) with string arguments containing line break / new line characters.

If I use Process.Start() method (in the calling program ) and Environment.GetCommandLineArgs() (in the called program ) to do this, it is equivalent to running the program from the command line. In this case, will be able to pass string arguments containing line break / new line characters without running into issues on either side?

Process.Start() calls CreateProcess() . There is no command line interpreter involved. This is not at all the same as running a process from the command line. The command line interpreter imposes restrictions on valid characters in a command line. You cannot pass a newline character through the command line (but you can through a call to CreateProcess() ).
