Asp.net mvc 如何在Combobox中将会话设置为ReceiveInvoice以保存下一个条目的接收ID

我想为下一个使用会话的条目使用接收发票，但它没有。在这里，我在create controller中填充Receive InvoiceNo。请帮帮我

  var rmaster = db.FactoryReceiveMaster.ToList();
        List<SelectListItem> lstFactoryReceiveMaster = new List<SelectListItem>();
        if (rmaster != null && rmaster.Count > 0)
        {
            foreach (var rInvoice in rmaster)
            {
                SelectListItem item = new  SelectListItem { Text = rInvoice.RInvoiceNo, Value = rInvoice.Receive_ID.ToString(), Selected = false };
                lstFactoryReceiveMaster.Add(item);
            }

        }
        Session["lstFactoryReceiveMaster"] = lstFactoryReceiveMaster;
        model.AssembleInvoice = lstFactoryReceiveMaster;

var rmaster=db.FactoryReceiveMaster.ToList（）；
List lstFactoryReceiveMaster=新列表（）；
如果（rmaster！=null&&rmaster.Count>0）
{
foreach（rmaster中的语音）
{
SelectListItem=new SelectListItem{Text=rInvoice.RInvoiceNo，Value=rInvoice.Receive_ID.ToString（），Selected=false}；
lstFactoryReceiveMaster.Add（项目）；
}
}
会话[“lstFactoryReceiveMaster”]=lstFactoryReceiveMaster；
model.AssembleInvoice=lstFactoryReceiveMaster；
