Email Entity Retrieve Data - Plug In - C#

Posted on by Community Member

Hello,

I'm trying to write a plugin for the email entity in Microsoft Dynamics CRM Online. Let's say its called "Sample_PlugIn".

I want the plugin to retrieve the sender of the email, and write his/her email address into a field (new_samplefield) of the email.

The Plugin does some other stuff as well (and it's all working), but this part of the code is the one making problems. (My organisation service reference is called "service".)

try                

{               
    Entity email = (Entity)context.InputParameters["Target"];

    EntityCollection fromCollection = (EntityCollection)email.Attributes["from"];

    if (fromCollection != null && fromCollection.Entities.Count > 0)
    {
        Entity sender = fromCollection[0]; 
        email["new_samplefield"] = (string)sender.Attributes["internalemailaddress"];
    }

    service.Update(email);
}

Every time the plug-in is executed, I get this error:

Unexpected exception from plug-in (Execute): Sample_PlugIn.Sample_PlugIn: System.Collections.Generic.KeyNotFoundException: The given key was not present in the dictionary.

It'd be great if anyone could help me - thanks a lot!

Hello,

Try to use following code:

try

{

Entity email = (Entity)context.InputParameters["Target"];

EntityCollection fromCollection = email.GetAttributeValue<EntityCollection>("from");

if (fromCollection != null && fromCollection.Entities.Count > 0)

{

Entity sender = fromCollection[0];

email["new_samplefield"] = sender.GetAttributeValue<string>("internalemailaddress");

}

service.Update(email);

}

Anyway I don't think that this code will work the way you want. Can you please explain your scenario?

Hi,

"from" is a partylist attribute - there are more examples here:

http://www.magnetismsolutions.com/blog/paulnieuwelaar/2015/09/07/working-with-dynamics-crm-activity-party-lists-in-c--plugins

You might need to replace

email["new_samplefield"] = (string)sender.Attributes["internalemailaddress"];

With

email["new_samplefield"] = (string)sender.Attributes["addressused"];

PS. If you move that plugin step to the pre-create, you may not need to call service.Update - setting "new_samplefield" attribute directly on the target should work

Just for the sake of completeness, this is the code that worked for me in the end. In this case, the sender is of entity systemuser. (I have registered this plug-in on "post-operation" and "Update".)

try

{

Entity email = (Entity)context.InputParameters["Target"];

// Post Entity Image (since the plug-in is registered on "Update")

Entity postImage = context.PostEntityImages["Image"];

EntityCollection fromCollection = postImage.GetAttributeValue<EntityCollection>("from");

if (fromCollection != null && fromCollection.Entities.Count > 0)

{

Entity sender = fromCollection[0];

EntityReference partyId = sender.GetAttributeValue<EntityReference>("partyid");

string entityType = partyId.LogicalName.ToString();

if (entityType == "systemuser")

{

// Create query using querybyattribute

QueryByAttribute queryToSender = new QueryByAttribute("systemuser");

queryToSender.ColumnSet = new ColumnSet("systemuserid", "internalemailaddress");

// Attribute to query

queryToSender.Attributes.AddRange("systemuserid");

// Value of queried attribute to return

queryToSender.Values.AddRange(partyId.Id);

EntityCollection retrievedFromSystemuser = service.RetrieveMultiple(queryToSender);

foreach (Entity systemuserE in retrievedFromSystemuser.Entities)

{

email["new_samplefield"] = (string)systemuserE.Attributes["internalemailaddress"];

}

}

}

service.Update(email);

}

Hi Nathalie! I know a plugin that can help log calls automatically in MS Dynamics. That app is Tenfold, a CTI and sales acceleration platform that offers features like call logging and call monitoring. You can check out Tenfold page if you'd like to know more. www.tenfold.com/.../dynamics
