SPRoleAssignment roleAssignment = new SPRoleAssignment(group);
SPRoleDefinition roleDefinition = site.RootWeb.RoleDefinitions["Read"];
roleAssignment.RoleDefinitionBindings.Add(roleDefinition);

2) ADD NEW GROUP TO SITE COLLECTION:
3) ASSOCIATE THE NEW GROUP TO A WEB:
4) ASSIGNMENT OF THE ROLES:
SPGroup group = web.Groups["MyNewGroup"];
if(user!=null && group!=null)
group.AddUser(user);

{
SPRoleAssColn.Remove(i);
}
The site collection contains a group named “All Members” with “Contributor” privilege.
I want to add this group programmatically to a sub site and modify its roles from “Contributor” to “Read” without modifying the original group.The following are the variables used in the code:
- site: the SPSite object of the site collection being used- web: the SPWeb object of the sub site you want to add the group to.
SOLUTION:
SPGroup group = site.RootWeb.SiteGroups["All Members"];SPRoleAssignment roleAssignment = new SPRoleAssignment(group);
SPRoleDefinition roleDefinition = site.RootWeb.RoleDefinitions["Read"];
roleAssignment.RoleDefinitionBindings.Add(roleDefinition);
if (!web.HasUniqueRoleAssignments)
web.BreakRoleInheritance(true);
web.RoleAssignments.Add(roleAssignment);

Working with Group: quick review:
1) BREAK INHERITANCE 2) ADD NEW GROUP TO SITE COLLECTION
3) ASSOCIATE THE NEW GROUP TO A WEB
4) ASSIGNMENT OF THE ROLES
5) ADD USERS TO THE GROUP
6) REMOVE ALL ROLES
1) BREAK INHERITANCE
if (!web.HasUniqueRoleAssignments)
web.BreakRoleInheritance(true);2) ADD NEW GROUP TO SITE COLLECTION:
web.SiteGroups.Add("MyNewGroup", web.AssociatedOwnerGroup, null, "MyNewGroup description");
web.AssociatedGroups.Add(group);
web.Update();
4) ASSIGNMENT OF THE ROLES:
SPGroup group = web.SiteGroups["MyNewGroup"];
SPRoleAssignment roleAssignment = new SPRoleAssignment(group);
SPRoleDefinition roleDefinition = site.RootWeb.RoleDefinitions["Read"];
roleAssignment.RoleDefinitionBindings.Add(roleDefinition);
web.RoleAssignments.Add(roleAssignment);
5) ADD USERS TO THE GROUP:
SPUser user = web.EnsureUser("domain\MyUser"); SPGroup group = web.Groups["MyNewGroup"];
if(user!=null && group!=null)
group.AddUser(user);
6) REMOVE ALL ROLES:
SPRoleAssignmentCollection SPRoleAssColn = web.RoleAssignments;for (int i = SPRoleAssColn.Count - 1; i >= 0; i--)
{
SPRoleAssColn.Remove(i);
}
