How to Unzip the .7zip file extension in C#?

public static void Extractallfiles(string srcPath, string destPath)
      {
          ZipForge archiver = new ZipForge();            
          archiver.FileName = srcPath;
              // Open an existing archive
              archiver.OpenArchive(System.IO.FileMode.Open);
              // Default path for all operations             
              archiver.BaseDir = destPath;
              // Extract all files from the archive to C:\Temp folder
              archiver.ExtractFiles("*.*");
              // Close archive
              archiver.CloseArchive();
      }

This code is doesn't support for .7zip format file, No issue with .zip file extension.
