C＃Process.Start：Whitespace甚至没有工作

Question

What I got:

Process.Start("cmd.exe", "/K \\"C:/Program Files/nodejs/node.exe\\" \\"C:/rc/rainingchain/app.js\\"");

Even though I wrapped the filename with escaped ", it still displays the error:

'C:/Program' is not recognized as an internal or external command, operable program or batch file.

What is wrong?

Answer 1

您需要在程序路径中使用两个“空格：

Process.Start("cmd.exe", "/K \"\"C:/Program Files/nodejs/node.exe\" \"C:/rc/rainingchain/app.js\"\"");

Answer 2

You code will be translated to

cmd.exe /K "C:/Program Files/nodejs/node.exe" "C:/rc/rainingchain/app.js"

cmd.exe will translate it to

C:/Program Files/nodejs/node.exe" "C:/rc/rainingchain/app.js That's why it complain errors.

What you need is to enclose whole node.exe command with double quote again.

Process.Start("cmd.exe", "/K \\"\\"C:/Program Files/nodejs/node.exe\\" \\"C:/rc/rainingchain/app.js\\"\\""); so the node.exe command will be "C:/Program Files/nodejs/node.exe" "C:/rc/rainingchain/app.js"

BTW, why don't just call node.exe directly?

Process.Start("C:/Program Files/nodejs/node.exe", "C:/rc/rainingchain/app.js");
