Hi All,
In your day today development you came across situation like you have a group name and you want to know the Permission levels(Role Definition) of that group.



In a following example we are going to have a demo on get the permission levels base on group name.

From the Main() Method:

List<string> role = new List<string>();
                Program obj = new Program();
                role = obj.GetRoleDefinition("MyProject Members");

                if (role != null)
                {
                    if (role.Count > 0)
                    {
                        Console.WriteLine("Role Defination:" + role[0]);
                    }
                }

Method:

        /// <summary>
        /// Used to get the Permission level of a group
        /// </summary>
        /// <param name="groupName">name of the Group</param>
        /// <returns>Permission Levels</returns>
        public List<string> GetRoleDefinition(string groupName)
        {
            try
            {
                using (SPSite oSite = new SPSite("SiteCollectionURL"))
                {
                    using (SPWeb oWeb = oSite.OpenWeb())
                    {
                        List<string> roleDef = new List<string>();
                        SPSecurity.RunWithElevatedPrivileges(delegate()
                        {
                            foreach (SPRoleAssignment roleAssignment in from SPRoleAssignment roleAssignment in oWeb.RoleAssignments where roleAssignment.Member is SPGroup where roleAssignment.Member.Name.Equals(groupName) select roleAssignment)
                            {
                                roleDef.AddRange(from SPRoleDefinition roleDefinition in roleAssignment.RoleDefinitionBindings select roleDefinition.Name);
                            }
                        });
                        return roleDef;
                    }
                }


            }
            catch (Exception ex)
            {
                throw;
            }
        }


Final Output:



Following simple console application will let us know about the requirement. In a attached Console after downloading and opening in VS. Please change the Site Collection Url and Group name and just run.You will see the out put.
