使用 Microsoft.Graph 将人员或组添加到任务列表时出现问题

Question

我使用 Microsoft.Graph，添加“人员”或“组”类型的字段时出现问题。现在显示的代码将一个新任务添加到 SharePoint 任务列表中，该任务基于服务器处理和发出的数据，但问题是没有显示应为其创建任务的 User，显然，它是未创建。

该项目使用 Microsoft Graph 版本 4.54.0。我很高兴收到有关此版本和更新版本的信息。预先感谢您的回复。

不确定它是否会产生任何影响，但是

AssignedTo

应该是

Edm.Int32

的集合，而不是

Edm.String

。

var lookupIds = usersArray.Select(user => user.LookupId).ToArray();

var requestBody = new ListItem
{
    Fields = new FieldValueSet
    {
        AdditionalData = new Dictionary<string, object>
        {
            { 
                "Title", item.Fields.AdditionalData["StatusLookupId"] ?? "Not specified"
            },
            {
                "[email protected]", "Collection(Edm.Int32)"
            },
            {
                "AssignedTo", lookupIds
            },
            { 
                "Body", parseXMLDate.Description ?? "Not specified" 
            }
        }
    }
};
