所以我试图从一个共享点列表中返回几个ListItems。我得到的内容还不错，但是当它反序列化内容时，计算所得的列将返回空值。我只是不明白，因为内容中有价值。
string geturl = "https://graph.microsoft.com/v1.0/sites/XXXXX.sharepoint.com,495435b4-60c3-49b7-8f6e-1d262a120ae5,0fad9f67-35a8-4c0b-892e-113084058c0a/lists/18a725ac-83ef-48fb-a5cb-950ca2378fd0/items/9?expand=fields(select=SerialNumber,id)";
public async Task<string> GetDataWithTokenAsync(string url, string token, string listitem)
{
var httpClient = new System.Net.Http.HttpClient();
System.Net.Http.HttpResponseMessage response;
try
{
var request = new System.Net.Http.HttpRequestMessage(System.Net.Http.HttpMethod.Get, url);
//Add the token in Authorization header
request.Headers.Authorization = new System.Net.Http.Headers.AuthenticationHeaderValue("Bearer", token);
response = await httpClient.SendAsync(request);
var content = await response.Content.ReadAsStringAsync();
var result = JsonConvert.DeserializeObject<SharePointListItems.RootObject>(content);
if (listitem == "id")
{
return result.fields.Id;
}
else
{
return result.fields.SerialNumber;
}
}
catch (Exception ex)
{
return ex.ToString();
}
}
这是课程（已缩短）：
public class SharePointListItems
{
public class Fields
{
[JsonProperty("@odata.etag")]
public string ODataETag { get; set; }
//General Parameters
...
public string SerialNumber { get; set; } // Calculated field in Sharepoint
public string Id { get; set; }
...
}
public class RootObject
{
[JsonProperty("@odata.context")]
public string ODataContext { get; set; }
[JsonProperty("@odata.etag")]
public string ODataETag { get; set; }
[JsonProperty("fields@odata.context")]
public string FieldsODataContext { get; set; }
public Fields fields { get; set; }
}
}
我的GET返回的内容是：
"{\"@odata.context\":\"https://graph.microsoft.com/v1.0/$metadata#sites('XXXXX.sharepoint.com%2C495435b4-60c3-49b7-8f6e-1d262a120ae5%2C0fad9f67-35a8-4c0b-892e-113084058c0a')/lists('18a725ac-83ef-48fb-a5cb-950ca2378fd0')/items/$entity\",\"@odata.etag\":\"\\\"a69b1840-239d-42ed-9b20-8789761fb06a,3\\\"\",\"createdDateTime\":\"2018-08-25T22:44:16Z\",\"eTag\":\"\\\"a69b1840-239d-42ed-9b20-8789761fb06a,3\\\"\",\"id\":\"9\",\"lastModifiedDateTime\":\"2018-08-25T22:44:16Z\",\"webUrl\":\"https://XXXXX.sharepoint.com/sites/GeneratorApp/Lists/GenApp/9_.000\",\"createdBy\":{\"user\":{\"email\":\"XXXXX@XXXXX.com\",\"id\":\"b0465821-e891-4f44-9e18-27e875f1b75d\",\"displayName\":\"XXXXX\"}},\"lastModifiedBy\":{\"user\":{\"email\":\"XXXXX@XXXXX.com\",\"id\":\"b0465821-e891-4f44-9e18-27e875f1b75d\",\"displayName\":\"XXXXX\"}},\"parentReference\":{},\"contentType\":{\"id\":\"0x0100E19591A4ECA81542AEA41A6AAFED6781\"},\"fields@odata.context\":\"https://graph.microsoft.com/v1.0/$metadata#sites('XXXXX.sharepoint.com%2C495435b4-60c3-49b7-8f6e-1d262a120ae5%2C0fad9f67-35a8-4c0b-892e-113084058c0a')/lists('18a725ac-83ef-48fb-a5cb-950ca2378fd0')/items('9')/fields/$entity\",\"fields\":{\"@odata.etag\":\"\\\"a69b1840-239d-42ed-9b20-8789761fb06a,3\\\"\",\"SerialNumber\":\"20180824-1353-DC6-Generator-A\",\"id\":\"9\"}}"
如果我添加一行
Jobject json = Jobject.Parse(content);
我收到以下响应（更改端点以获取多个ListItem）：

好像我现在正在转一圈。
我最后想要的是ID和序列号列表。
[更新代码以反映我的评论]
答案 0 :(得分：0)
由于我确实回答了该主题的问题，所以我要问的第二件事是一个完全独立的问题。
所以发生的事情是我看错了数据。我正在查看的区域也恰好有一个“ id”字段，因此显示的是“ id”，而不是我真正想要的那个。当我设置适当的入口点时，我可以在相应的字段下进行操作。
