C # Process.Start: spaces don't work even in quotes

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 the escaped ", it still displays the error:

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

What's wrong?

You need to use two spaces in the program path:



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

Your 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

This is why he complains about mistakes.



You will need to wrap the whole node.exe command with a double quote again.

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

so the node.exe command would be "C:/Program Files/nodejs/node.exe" "C:/rc/rainingchain/app.js"

By the way, why not just call node.exe directly?

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