Create , Assign and Retrieving Field Permission in C# 2011

In this article , I am explaining how to create Field Security Profile using FieldSecurityProfileClass
and assign profile to team or user using AssociateRequest Class
I next step , I am assigning Role Preveliage to custom entity “new_payment” using AddPrivilegesRoleRequest class and assign
Field permission to specific attribute of “new_payment” entity
In last step , Retrieving user assigned Profile and permission of Security Profile
Namespace need to include

using Microsoft.Xrm.Sdk;
using Microsoft.Xrm.Sdk.Client;
using Microsoft.Xrm.Sdk.Messages;
using Microsoft.Xrm.Sdk.Query;
using Microsoft.Crm.Sdk.Messages;

                 "Marketing Manager")
             }
         }
     };
     Role role = (Role)_serviceProxy.RetrieveMultiple(roleQuery).Entities[0];
     Guid _roleId = role.Id;

Add privileges for the Payment entity to the Marketing Role

    RolePrivilege[] privileges = new RolePrivilege[3];
    privileges[0] = new RolePrivilege();
    privileges[0].PrivilegeId = new Guid("{9245fe4a-d402-451c-b9ed-9c1a04247482}");

Query to obtain the field security profiles

    // Create list for storing retrieved profiles.
    List<Guid> profileIds = new List<Guid>();

    // Build query to obtain the field security profiles.
    QueryExpression qe = new QueryExpression()
    {
       EntityName = FieldSecurityProfile.EntityLogicalName,
       ColumnSet = new ColumnSet("fieldsecurityprofileid"),

    };
    RetrieveMultipleRequest rmRequest = new RetrieveMultipleRequest()
    {
       Query = qe
    };
    EntityCollection bec = ((RetrieveMultipleResponse)_serviceProxy.Execute(
                    rmRequest)).EntityCollection;

    // Extract profiles from query result.
    foreach (FieldSecurityProfile profileEnt in bec.Entities)
    {
        profileIds.Add(profileEnt.FieldSecurityProfileId.Value);
    }

Retrieve attribute permissions of a FieldSecurityProfile

    DataCollection<Entity> dc;
    QueryByAttribute qba = new QueryByAttribute(FieldPermission.EntityLogicalName);
    qba.AddAttributeValue("fieldsecurityprofileid", _profileId);
    qba.ColumnSet = new ColumnSet("attributelogicalname");
