using Microsoft.SharePoint.Administration;

namespace Retrive_Solutions

{ 

    class SolutionBackup

    {

        static void Main(string[] args)

        {

            SPSolutionCollection AllSolutions = SPFarm.Local.Solutions;

            foreach (SPSolution Solution in AllSolutions)

            {

                SPPersistedFile wspFile = Solution.SolutionFile;

                wspFile.SaveAs("C:\\Solutions\\" + Solution.Name);
