C# 无法使用csom更新具有查找表GUID的任务或项目的CustomField

是否有人在使用查找值的任务或项目上以编程方式更新自定义字段？我使用的是CSOM，代码如下，c#。查找自定义字段不会更新，但字段设置为空，覆盖以前使用Web App输入的值。“文本”自定义字段的更新工作正常

private void SendCode()
{
    ProjectContext context;
    using (context = new ProjectContext(ConfigurationManager.AppSettings["psUrl"]))
    {
        context.Load(context.Projects,
            pj => pj.Include(
                p => p.Id,
                p => p.Name));
        context.Load(context.CustomFields,
            lts => lts.Include(
                lt => lt.Name,
                lt => lt.InternalName));

        context.ExecuteQuery();
        // Output Status is a Custom Filed referring to a lookup table called Output Status with 6 status values
        string customFieldName = "Output Status";
        // A routine to get the correct GUID from the lookup Table
        object customFieldValue = new Guid("1aded2bc-67ad-49e4-9c52-a9dca4ea09a5");
        foreach (PublishedProject pp in context.Projects)
        {
            DraftProject proj2Edit = pp.CheckOut().IncludeCustomFields;
            context.Load(proj2Edit.Tasks,
                ts => ts.Include(
                    t => t.Id,
                    t => t.Name,
                    t => t.CustomFields,
                    t => t.OutlineLevel,
                    t => t.IsSummary));
            context.ExecuteQuery();
            var cfInternalName = context.CustomFields.First(cf => cf.Name == customFieldName).InternalName;
            DraftTask newTask = proj2Edit.Tasks.First(t => t.Name == "REI and PPR Monitoring");
            newTask[cfInternalName] = customFieldValue;  // How should you be setting the GUID?
            proj2Edit.Publish(true);
            QueueJob qJob = context.Projects.Update();
            JobState jobState = context.WaitForQueue(qJob, QueueTimeout);
        }
    }
}

找到了解决办法。您传递的不是查找GUID，而是查找条目的网名。该值应该类似于“Entry\uux…”

这些帖子非常有用：
