Adding site column to the list at any site level

Hi All,

May times we require to add columns defined at root web level to any site at child level.

Here is a simple way to accomplish this :

Make one function like this :

private void AddSiteColumnToList(string sitePath, string listName, string columnName)
{
using (SPSite site = new SPSite(sitePath))
{
using (SPWeb web = site.OpenWeb())
{
using (SPWeb root = site.RootWeb)
{
//Take the site column from the root web
SPField fld = root.Fields[columnName];

//get the list from the site
SPList list = web.Lists[listName];

//add the column
list.Fields.Add(fld);

//update the list
list.Update();
}
}
}

That's it. Your job is done.

Thank you
