Step 2:- Complete Code

using System.Diagnostics;

string SevenZipPath = @"C:\Program Files\7-Zip\7z.exe";

string FilePath = @"D:\Test\Files";

ProcessStartInfo processStartInfo = new ProcessStartInfo(SevenZipPath);

processStartInfo.Arguments = string.Format("a -t7z {0}.7z {0}", FilePath);

processStartInfo.RedirectStandardInput = true;

processStartInfo.UseShellExecute = false;

processStartInfo.CreateNoWindow = true;

processStartInfo.WindowStyle = ProcessWindowStyle.Hidden;

Process process = Process.Start(processStartInfo);

Step 3:-Explanation

Get the 7-Zip installed path
