How to convert a FetchXML query to LINQ?

$

Hi,

I've exported two Advanced Find queries to query queues with inactive mailboxes and unapproved emails within CRM. Now I want to create this same query using LINQ in a solution using the CRM SDK 2015.

I started by exporting the FetchXML queries and then tried converting them to their LINQ equivelant.

Advanced Find queries -

1.Look For: Queues

Select ->

Mailbox(related) ->

Status -> Equals -> Inactive

2.Look For: Queues

Primary Email Status -> Equals -> Pending Approval; Rejected


Fetch XML Queries -

Mailbox:

<?xml version="1.0"?>

-<fetch distinct="false" mapping="logical" output-format="xml-platform" version="1.0">


-<entity name="queue">

<attribute name="name"/>

<attribute name="emailaddress"/>

<attribute name="queueid"/>

<order descending="false" attribute="name"/>


-<filter type="and">


-<condition attribute="emailrouteraccessapproval" operator="in">

<value>2</value>

<value>3</value>

</condition>

</filter>

</entity>

</fetch>




Email:

<?xml version="1.0"?>

-<fetch distinct="false" mapping="logical" output-format="xml-platform" version="1.0">


-<entity name="queue">

<attribute name="name"/>

<attribute name="emailaddress"/>

<attribute name="queueid"/>

<order descending="false" attribute="name"/>


-<link-entity name="mailbox" alias="ab" to="defaultmailbox" from="mailboxid">


-<filter type="and">

<condition attribute="statecode" value="1" operator="eq"/>

</filter>

</link-entity>

</entity>

</fetch>

This is my attempt at each query in LINQ which don't return the same results as the fetch queries -

Unnaproved Email query:

List<Entity> queues = (from q in sourceContext.CreateQuery("queue")
                       where q.GetAttributeValue("emailrouteraccessapproval").Equals(false)
                       select q).ToList();

Disabled Mailbox query:

List<Entity> queues = (from q in sourceContext.CreateQuery("queue")
                       where q.GetAttributeValue("defaultmailbox").Equals(false)
                       select q).ToList();


 

Does anyone know the correct LINQ conversion for the above two FetchXML queries?
