检索发票时检索发票详细信息

Question

我有这个简单的 LINQ to CRM 查询：

//retrieve all invoices associated to the cycle...
List<Invoice> invoiceCycleInvoices = ctx.InvoiceSet.Where(x => x.new_invoice_cycle_invoicesid.Id == invoiceCycle.Id
    && x.new_erpsync == false
    && x.StateCode != InvoiceState.Canceled).ToList();

通常，ToList 调用会拉取延迟加载忘记的所有相关信息，但是在 Invoice 中有一个名为 invoice_details 的 属性 始终为空。

如何一次性填充它？

Answer 1

应该是：

List<Invoice> invoiceCycleInvoices = ctx.InvoiceSet
    .Where(x => x.new_invoice_cycle_invoicesid.Id == invoiceCycle.Id
        && x.new_erpsync == false
        && x.StateCode != InvoiceState.Canceled)
    .Include(x => x.invoice_details)
    .ToList();

Answer 2

使用 LoadProperty 访问实体关系。

foreach (var invoice in invoiceCycleInvoices)
{
    ctx.LoadProperty(invoice, "invoice_details");
    var invoiceDetail = invoice.GetRelatedEntity<Entity>("invoice_details");
}
