Create a site collection policy programmatically

Question

I have a requirement to create a site collection policy (retention policy) programmatically. It can be either a powershell script or in C# using Visual Studio 2010. I did a lot of research and am not able to find a solution. Can anybody please help.

Thanks & Regards,

Vishnu

Answer 1

In SharePoint 2010 you can apply the retention policy to a content type, to a list or document library or to a folder.

by reading that I don't think you can apply it to site collection, did you tried any procedure manually that you want to do using coding or script ?

EDIT

try this then

there is a Retention policy class at MSDN article

for example

 public static void AddPolicyToContentType()
 { 
            using(SPSite site = new SPSite("http://basesmcdev2/sites/tester1"))
            {
                using(SPWeb web = site.OpenWeb())
                {
                    SPList list = web.Lists["tester2"];
                    SPContentType ctype = list.ContentTypes["Document"];

                    if (Policy.CanHavePolicy(ctype))
                    {
                        PolicyCatalog pc = new PolicyCatalog(site);
                        var policy = (from p in pc.PolicyList.OfType<Policy>() where p.Name == "expireme" select p).First();
                        Policy.CreatePolicy(ctype, policy);
                        Policy.ProcessChanges(site);

                    }
                }

 }

The documentation is a little thin for creating retention policies. Hopefully this will get you started:
