是否必须对activityparty类型进行一些初始化?代码、字段电子邮件没有问题。要返回EntityCollection并获取您需要使用的内容,请使用:
var entityCollection = email.GetAttributeValue<EntityCollection>("to");
var entityCollection=email.GetAttributeValue(“to”);
这将为您提供需要转换为ActivityParty(entityCollection.entities)的实体集合。
要转换所需的实体,请执行以下操作:
foreach (var entityItem in entityCollection.Entities)
{
var ap = entityItem.ToEntity<ActivityParty>();
//Here you will get the LogicalName in this case Lead
// the Id and the name
var leadId = ap.PartyId.Id;
//To get the Lead
var lead=context.LeadSet.FirstOrDefault(l => l.Id == leadId);
}
foreach(entityCollection.Entities中的var entityItem)
{
var ap=entityItem.ToEntity();
//在这里,您将获得本案例Lead中的LogicalName
//Id和名称
var leadId=ap.PartyId.Id;
//领先
var lead=context.LeadSet.FirstOrDefault(l=>l.Id==leadId);
}
foreach (var entityItem in entityCollection.Entities)
{
var ap = entityItem.ToEntity<ActivityParty>();
//Here you will get the LogicalName in this case Lead
// the Id and the name
var leadId = ap.PartyId.Id;
//To get the Lead
var lead=context.LeadSet.FirstOrDefault(l => l.Id == leadId);
}
