What are the permission levels in SharePoint? /Can we create our own custom permission levels?

SharePoint - Create Custom Permission Level and List All available Permission

I am going to show programmatically how we can list all available permission in a SharePoint site and how we can show the detail of any permission ie. name, description, base permission etc..

I am also showing how we can create our own custom permission in SharePoint programmatically.

For this I created Blank SharePoint Solution and mapped it with our SharePoint site. I added 2 pages here..

1. GetAllPermission.aspx (To show all permission)

2. AddNewPermission (To add a custom permission).

I deployed the solution and my functionality is:

To Add a new custom Permission...

After Creating New Permission you can check in SharePoint Site:
