Zip multiple files using 7zip.exe in C#

Question

I have to zip multiple files together using 7zip.exe. I have paths of two files say file1 and file2. I append the two paths using the following. string filetozip = file1+ "\"" + file2+" "; and do the below

        Process proc = new Process();
        proc.StartInfo.FileName = @"C:\Freedom\7-Zip\7z.exe";
        proc.StartInfo.UseShellExecute = false;
        proc.StartInfo.RedirectStandardError = true;
        proc.StartInfo.RedirectStandardInput = true;
        proc.StartInfo.RedirectStandardOutput = true;

       proc.StartInfo.Arguments = string.Format("    a -tzip \"{0}\" \"{1}\" -mx=9 -mem=AES256 -p\"{2}\"    ", destZipFile, filetozip , zipPassword);
        proc.Start();

        proc.WaitForExit();

        if (proc.ExitCode != 0)
        {
           throw new Exception("Error Zipping Data File : " + proc.StandardError.ReadToEnd());
        }

filetozip is passed as an argument above. The above code does not work properly. I am getting proc.ExitCode=1. Which is the right way to append the file paths.Is string filetozip = file1+ "\"" + file2+" "; the right way? I can have one or more files. What is the separator used?

Do you have to use 7zip.exe? As of .Net 3.0, a zip class is built in: http://stackoverflow.com/questions/940582/how-do-i-zip-a-file-in-c-using-no-3rd-party-apis — Steve Wellens, Mar 15 '15 at 14:39

The command line that you want to create looks like

plus the required switches (arguments quoted and space delimited).

String.Join or StringBuilder are some coding things that may be helpful
