Question

我有这个简单的LINQ to CRM查询：

＆＃xA;＆＃xA;

  //检索与周期相关的所有发票...＆＃xA; List＆lt;发票＆GT; invoiceCycleInvoices = ctx.InvoiceSet.Where（x =＆gt; x.new_invoice_cycle_invoicesid.Id == invoiceCycle.Id＆＃xA;＆amp;＆amp; x.new_erpsync == false＆＃xA;＆amp;＆amp; x.StateCode！= InvoiceState.Canceled ）.ToList（）;＆＃xA;

＆＃xA;＆＃xA;

通常， ToList 调用会提取延迟加载忘记的所有相关信息，但是 Invoice 中有一个名为 invoice_details 的属性，该属性始终为null。

＆＃xA;＆＃xA;

如何填充它一举？

Answer 1

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");
}

Answer 2

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();

检索发票时检索发票详细信息
