Question

我正在尝试使用以下代码在CRM 2011中保存注释实体：

var annotationContext = new CrmOrganizationServiceContext(crmOrganizationService);
var annotation = annotationContext.CreateEntity("annotation");
annotationContext.AddObject(annotation);
// Setting the account id.
entity.SetAttributeValue<EntityReference>("objectid", "account", "Guid of the account");    
entity.iCrmSetPropertyValue(AnnotationDefinition.ColumnsName.DocumentBody,Convert.ToBase64String(new UnicodeEncoding().GetBytes("Sample Annotation Text")));
entity.iCrmSetPropertyValue("isdocument",true);
entity.iCrmSetPropertyValue(AnnotationDefinition.ColumnsName.Mime, "text/plain");
entity.iCrmSetPickListValue(AnnotationDefinition.ColumnsName.ObjectType, 1);
entity.iCrmSetPropertyValue(AnnotationDefinition.ColumnsName.Subject, "CompanyLogo");
annotationContext.SaveChanges();

保存更改方法失败，并在crm服务器的事件查看器中显示以下错误：

您正在将annotation变量添加到上下文中，但更新实体对象。
