我有几个返回不同通用列表的方法.

在.net中存在任何类静态方法或将任何列表转换为数据表的任何东西？我唯一可以想象的是使用Reflection来做到这一点.

如果我有这个:

List<Whatever> whatever = new List<Whatever>();

(下一个代码当然不起作用,但我想有可能:

DataTable dt = (DataTable) whatever;

有没有一种简单的方法来填充我的C#对象与通过AJAX传递的JSON对象？

//这是使用JSON.stringify从页面传递给C#WEBMETHOD的JSON对象

{
    "user": {
        "name": "asdf",
        "teamname": "b",
        "email": "c",
        "players": ["1", "2"]
    }
}

// C#WebMetod接收JSON对象

[WebMethod]
public static void SaveTeam(Object user)
{

}

// C#类,表示传入WebMethod的JSON Object的对象结构

public class User
{
    public string name { get; set; }
    public string teamname { get; set; }
    public string email { get; set; }
    public Array players { get; set; }
}

我想一般扁平一些json所以我可以转换为数据表并使用c#绑定到数据网格

什么是最好的办法,记住我不知道我要下多少级别？

例如

{
  "appointmentid": 4,
  "policyid": 1,
  "guid": "00000000-0000-0000-0000-000000000000",
  "number": "1234567890",
  "ampm": "false",
  "date": "2015-09-08T00:00:00",
  "vehicle": {
    "id": 1,
    "guid": "00000000-0000-0000-0000-000000000000",
    "make": null,
    "model": null
  },
  "installer": {
    "installerid": "1",
    "name": "Installer 1",
    "contact": "qwerty",
    "qascore": "0",
    "address1": "qwerty",
    "address2": "qwerty",
    "address3": null,
    "address4": null,
    "city": "qwertyu",
    "county": "qwertyu",
    "postcode": "asdfghj",
    "country": "GB",
    "email": "asdfghj",
    "web": "asdfghjk",
    "archived": false
  },
  "installations": [
    {
      "installationid": 6,
      "installationstatus": {
        "installationstatusid": 4,
        "installationstatus": "FAIL"
      },
      "isactive": true
    },
    {
      "installationid": 7,
      "installationstatus": …

有谁知道如何从asp.net将json字符串转换为DataTable？我开始了解Deserialize,它需要类,我只想要返回数据表.谁能告诉我如何将其转换为数据表？

我正在使用Web服务创建一个C#应用程序.在我的Web服务中,我正在使用JSONString数据.但我无法将此字符串转换为DataSet.

我JSONString是:

{
    "Table": [
        {
            "DisplayVoucherNumber": "A101239Z",
            "ActualDate": "08/07/2013",
            "AccountName": "shyamal",
            "Pcs": "50",
            "Weight": "500.000"
        }
    ],
    "Table1": [
        {
            "DisplayVoucherNumber": "R101249B",
            "ActualDate": "11/07/2013",
            "AccountName": "vipul",
            "NetWeight": "90.000",
            "Weight": "80.000",
            "Difference": "10.000"
        },
        {
            "DisplayVoucherNumber": "R101249B",
            "ActualDate": "11/07/2013",
            "AccountName": "vipul",
            "NetWeight": "500.000",
            "Weight": "100.000",
            "Difference": "400.000"
        }
    ]
}

我正在尝试将JSON文本序列化为DataTable,如下所示.

List<Dictionary<string, string>> list = 
JsonConvert.DeserializeObject<List<Dictionary<string, string>>>(jsonText);
DataTable dTable;
dTable = (from p in list select p).CopyToDataTable();

我收到以下错误.我如何解决它？

错误:

Cannot deserialize JSON object into type 
'System.Collections.Generic.List`1[System.Collections.Generic.Dictionary`2
[System.String,System.String]]'.
