any design pattern can use in dynamic permission assignment for specific role

See more:

C#

.NET

MVC

Actually many times I create code
For permission assessment for role

Like
Admin role have permission like add user view user delete user

If you select add user then by default view user permission added in your list
Add if you remove view user then all releted add delete edit permission will gone from list
Some times both approval permission and verifier permission cant assign to single role this type of checking


For different roles many permission near about 30 are there

I added hell lot of if else conditions

If this add this etc looking very bad


So I am searching for easy way to do this
