Retrieve WSP from Sharepoint CentralAdmin

I am a sharepoint devloper,but there are times when I have to jump into deployment activity and obviously I have to struggle even to do simple things.So recently my requirement was to get a wsp from one server and deploy it to another server.Sounds very simple but It wasn't for me unless I found the right way to do it.So thanks to powershell which helped me with it.Here is what  I did

So all you you need to do is open the Powershell and run the following command in order to get the WSP file.

$myFarm = Get-SPFarm
$myWSP = $myFarm.Solutions.Item(“mywsp.wsp”).SolutionFile
$myWSP.SaveAs(“C:\wspFolder\mywsp.wsp”)

This simple piece of command will get you the WSP File.and if you don't want to use powershell and love writing code then write following pience of code on a button click or execute it the way  you want it to work.

void getWSP_Click(object sender, EventArgs e)
        {
            SPSolutionCollection allSolutions = SPFarm.Local.Solutions;
            foreach (SPSolution solution in allSolutions)
            {
                SPPersistedFile wsp= solution.SolutionFile;
                if (wsp.Name == "mywsp.wsp")
                {
                    wsp.SaveAs("c:\\wspFolder\\" + solution.Name);
                }
            }
        }

Thanks for Reading and Hope this works for you.
