Adding “Everyone” Permissions Programmatically in SharePoint 2013

Introduction

Normally, we are having permission level operations in SharePoint. We may assign such kind of permission both manually and programmatically. Here, we will see how to give permission to "Everyone" programmatically

Code

SPUser allUsers = web.AllUsers[@”c:0(.s|true”]; //c:0(.s|true is Everyone

SPRoleDefinitionCollection roleCollection = web.RoleDefinitions;

SPRoleDefinition roleDefinition = roleCollection[“Visitors”];

SPRoleAssignment roleAssignment = newSPRoleAssignment((SPPrincipal)allUsers);

roleAssignment.RoleDefinitionBindings.Add(roleDefinition);

list.BreakRoleInheritance(false);

list.RoleAssignments.Add(roleAssignment);

list.Update();

Powershell script

Set-SPUser -Identity "c:o(.s\true" -web "webUrl" -Group "Visitors"
