Running Commands from C#

Question

Worst topic but can't really say much more.

Thing is, i am trying to run a certain command from cmd, if i do this normally in windows, it's flawless, in C# it doesn't work, even though it's the exact same string.

Here is how i do it:

        Process cwebp = new Process();
        cwebp.StartInfo.FileName=("cmd.exe");
       cwebp.StartInfo.Arguments = Settings.EncoderSettings[0];
       cwebp.Start();

And well arguments is pretty much anything, for example:

opusenc --bitrate 100 input.wav output.opus

Is there any fundamental issue here? Been searching a lot and can't find any information, everything says (use Arguments), and i do, and it doesn't work as expected.

Answer 1

除了史蒂夫的答案，您可以直接启动命令，而无需首先使用cmd ：

Process.Start("opusenc", "--bitrate 100 input.wav output.opus");

Answer 2

To execute a shell command you need to add the parameter /C (/K) on the arguments line

 Process cwebp = new Process();
 cwebp.StartInfo.FileName=("cmd.exe");
 cwebp.StartInfo.Arguments = "/C " + Settings.EncoderSettings[0];
 cwebp.Start();

Without it, the Process.Start method starts the cmd command processor, but, this one, exits immediately without processing the passed arguments.
