Dynamics CRM如何分辨C＃捆绑包中的哪些产品

Question

I have a program that bills a customer based on a custom entity. It is a subscription based process. We enter an order, if that order has a product that has been defined as a subscription product then the custom entity is created. The product can be either a single product or it can be a bundle. When the subscription ends I need to end the ability of the customer to continue to use the software.

I can read the product and I can determine if the product is a bundle by examining the attribute "productstructure". How do I determine which products are included in the bundle?

Thanks

If you retrieve the product you can use "productstructure" to determine if it is a bundle. If the value is a 3 it is a bundle.

You can then query the "productassociation" table where the attribute "productid" equals the Id of the bundle.

The attribute you need to retrieve from the "prodctassociation" table is "associatedproduct". You then retrieve the product instance.

QueryExpression productBundleQuery = new QueryExpression();
productBundleQuery.Distinct = false;
productBundleQuery.EntityName = "productassociation";
productBundleQuery.ColumnSet = new ColumnSet("associatedproduct");
productBundleQuery.Criteria = new FilterExpression
{
     Conditions = { new ConditionExpression("productid", ConditionOperator.Equal, bundle.Id) }
};

EntityCollection productBundleCollection = _service.RetrieveMultiple(productBundleQuery);

foreach (Entity productAssociation in productBundleCollection.Entities)
{
    Entity product = _service.Retrieve("product", ((EntityReference)productAssociation["associatedproduct"]).Id, new ColumnSet("name", ...));

    Do something....
 }
