Impersonation in Sharepoint

In a scenario I have to implement the impersonation. In this, user X has to impersonate user Y, so that the user X can access all the functionalities of the user Y. For this implementation, we need to have the user token of the user Y, which can be used when X impersonates user Y.

To achieve this, follow the following code snippet

STEP 1: Retrieve the SPUserToken of the user Y.

SPUserToken UserYtoken;

string URL = SPContext.Current.Site.Url;

using (SPSite objSite = new SPSite(URL))

{

using (SPWeb objWeb = objSite.OpenWeb())

{

SPUser UserY = objWeb.EnsureUser(“@Domain\\UserName”);

UserYtoken = UserY.UserToken;

}

}

STEP 2: User X can impersonate user Y using the following code snippet.

using (SPSite objSite = new SPSite(URL, UserYtoken))

{

using (SPWeb objWeb = objSite.RootWeb)

{

//Now the current context is of User Y and user X can access the contents that User Y can

}

}

Happy Coding..!!!
