CRM 2011插件-查询与数组中的值匹配的记录

Question

I just discovered this great site and would like to thank everyone in advance for any help.

I am working on a plugin that would update contact's email address where the contact's email matches one of the emails in an array. We use a 3rd party marketing tool for sending out mass email campaigns. We want to take all the soft bounce emails we have and update the CRM and clear the bad email from the system. I have an idea to create a plugin where I declare a string array of all the email addresses that bounced. Then run a query of contacts where the email address matches any one of the values in the array. If it matches I would simple update the email address field. Is something like this possible?

I know how to set up the array and query records but what I can't seem to find an example of is where the query looks for the contact email address to match any one of the values in the array. I only find examples where it looks for a specific value from within the array, like 'contact.emailaddress = "name@email.com"'.

Thanks again for any help.

It's possible yes, but you will have to step through the entire array.

So 1st part: I assume you know how to identify that array inside the plugin.

2nd part: you already know how to query the Contact entity for a specific e-mail address

3rd part: Just repeat the example you found to find contact.emailaddress = "name@email.com" for each item in the array of e-mail addresses you have.

foreach (string email in emailAddressArrayFrom3rdPartyTool)
{
    //Query for the contacts that match that e-mail address here
    //Update Contacts so that the e-mail address is removed.
}

You can also define a List and populate it with Contacts you want to update it. Then you can call the updates when you have tracked down all the records.

Update: You can also go the Fetch XML route: (more info here: http://msdn.microsoft.com/en-us/library/gg328117.aspx )

string fetch = @"
   <fetch mapping='logical'>
     <entity name='contact'> 
        <attribute name='contactId'/> 
           <filter> 
              <condition attribute='emailaddress' operator='in'>
                    <value>List of Array emails here</value>
                    <value>List of Array emails here</value>
                    <value>List of Array emails here</value>
                </condition>
           </filter> 
     </entity> 
   </fetch> "; 

EntityCollection result = _serviceProxy.RetrieveMultiple(new FetchExpression(fetch));

foreach (var c in result.Entities)
   {
   System.Console.WriteLine(c.Attributes["name"]);
   }
