Sending arguments to the command line

Question

I need to unzip a compressed file with the command line version of 7zip. This one liner should to the trick:

Process.Start("cmd", @"C:\Users\cw\Downloads\7za920\7za e C:\UPDATED.zip -oc:\");

I'm specifying the path to the 7zip command line executable, and telling it which file to unzip. If I copy and paste those arguments into my command line window, it will work. In C#, it will bring up a command line window, and nothing will happen. What gives?

Answer 1

尝试：

Process.Start("cmd", @"/c C:\Users\cw\Downloads\7za920\7za e C:\UPDATED.zip -oc:\"); 

Answer 2

It's because you're running cmd.exe, and not 7za directly. You can do either of the two:

Process.Start(@"C:\users\...\7za", "e c:\updated.zip -oc:\");

or

Process.Start("cmd", @"/c c:\users\...\7za e c:\updated.zip -oc:\");

The /c flag tells cmd to run the arguments after starting.

Answer 3

尝试

Process.Start(@"C:\Users\cw\Downloads\7za920\7za.exe", @"e C:\UPDATED.zip -oc:\");
