Give site level permission to user

Question

I want to give site level permission to user programmatically. I want that user can only be able to view the site. How can I do this?

Answer 1

You could use PowerShell to do this:

Set-SPUser -Identity 'domain\user_name' -Web http://siteCollection/site -AddPermissionLevel Read

Answer 2

If you are looking for granting the user permission through SharePoint Object Model Programming then the below code should help you. Not sure how you would prefer executing the below code. But yes you may put this code in an Event Receiver or Console Application, the choice is yours.

SPSecurity.RunWithElevatedPrivileges(delegate()
{
 using(SPSite spSite = new SPSite("yourSite")
 {
 using(SPWeb spWeb = spSite.OpenWeb())
 {
  //get current permission definitions so we can apply permissions
  SPRoleDefinitionCollection roleDefs = spWeb.RoleDefinitions;

  //get a specific user or ad security group by username
  SPUser myUser = web.EnsureUser(@"domain\username");
  SPRoleAssignment addUser = new SPRoleAssignment(myUser);

  //create new roles binding for user or group
  SPRoleDefinitionBindingCollection bindUser = addUser.RoleDefinitionBindings;

  //give read permission to the user
  bindUser.Add(roleDefs[“Read”]);
  spWeb.Update();
  }
 }
});
