In this article i share with you a sample function that provide us code impersonation.For example you have login to sharepoint as system account and what to add an item to a custom list but you impersonate it by another user. As you know SPSecurity.RunWithElevatedPrivileges can provide us to run code as Sharepoint\system account.
So what if you impersonate with another user. The main key point is SPSite object constructor has parameter as SPUserToken, if you pass this token to the constructor,
it provide execute code with related user rights as defined with SPUserToken. For a real code impersonation you should better to use some native dll references (AdvApi32 DLL) . but this is also work for simple operations well.
Here the RunAsAdmin static class that contains ImpersonateRun fuction getting 2 parameters .
1) Account : the account to use rights
2) RunWithAdminDelegate : which is a delegate that provide us writing less codding for our implementations using lambda functions
the usage is very simple , Less coded less simple .
see you next time.
