用PowerShell批量收回wsp包

转：http://www.xuebuyuan.com/168334.html

提供wsp部署的参数：$wspnames：路径下的所有wsp文件名用逗号隔开，如“sumhtestwsp.wsp,sumhtestwsp123.wsp,sumhtestwsp456.wsp,sumhtestwsp789.wsp”

方法：
#收回解决方案，并删除解决方案管理区的解决方案
function recoverWSP([string] $wspnames)
{
    $PSSnapinSharePoin = Get-PSSnapin Microsoft.SharePoint.PowerShell -ErrorAction silentlycontinue
    if( $PSSnapinSharePoin -eq $Null)
    {
         Add-PSSnapin Microsoft.SharePoint.PowerShell;
    }
    foreach($wspname in $wspnames.split(','))
    {
        $gspsolution = Get-SPSolution -Identity $wspname
        if($gspsolution -ne $null)
        {
            #1.收回解决方案
            if($gspsolution.Deployed)  
            {
                Uninstall-SPSolution -AllWebApplications -Identity $wspname
            }
            #2.删除解决方案管理区的解决方案
            Remove-SPSolution -Identity $wspname -Confirm:$false
        }
    }
}

例如：
recoverWSP -wspnames  “sumhtestwsp.wsp,sumhtestwsp123.wsp,sumhtestwsp456.wsp”
