嗨我通过调用外部api获得json结果.

        HttpClient client = new HttpClient();
        client.BaseAddress = new Uri(url);
        client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
        HttpResponseMessage response = client.GetAsync(url).Result;

        if (response.IsSuccessStatusCode)
        {
            var result  = response.Content.ReadAsStringAsync().Result;
            var s = Newtonsoft.Json.JsonConvert.DeserializeObject(result);
            return "Success";
        }
        else
        {
            return "Fail";
        }

var s = Newtonsoft.Json.JsonConvert.DeserializeObject(result);我得到的结果是:

 {{

  "topScoringIntent": {
    "intent": "1",
    "score": 0.9978111,
    "actions": [

        "parameters": [
          {
            "name": "1",
            "required": true,
            "value": null
          },
          {
            "name": "1",
            "required": true,
            "value": null
          },
          {
            "name": "1",
            "required": true,
            "value": …

我正在尝试在postgres中创建和使用新数据库.当我尝试使用以下命令加载数据库时:

sudo -u postgres psql

我收到这个错误.

无法将目录更改为"/ home/laptop/Dropbox/js/hw/Has-Many-Relationships":权限被拒绝psql(9.3.13)输入"help"获取帮助.

我试图以root身份更改nautilus中的文件夹权限.当文件夹更改为root(cp和cd /)时,此命令将按预期工作任何想法？

我有这个JSON，我必须反序列化它：

{
  "homepage": "http://files.minecraftforge.net/maven/net/minecraftforge/forge/",
  "promos": {
    "1.10-latest": "12.18.0.2000",
    "1.10.2-latest": "12.18.1.2014",
    "1.10.2-recommended": "12.18.1.2011",
    "1.5.2-latest": "7.8.1.738",
    "1.5.2-recommended": "7.8.1.737",
    "1.6.1-latest": "8.9.0.775",
    "1.6.2-latest": "9.10.1.871",
    "1.6.2-recommended": "9.10.1.871",
    "1.6.3-latest": "9.11.0.878",
    "1.6.4-latest": "9.11.1.1345",
    "1.6.4-recommended": "9.11.1.1345",
    "1.7.10-latest": "10.13.4.1614",
    "1.7.10-latest-1.7.10": "10.13.2.1343",
    "1.7.10-recommended": "10.13.4.1558",
    "1.7.2-latest": "10.12.2.1147",
    "1.7.2-recommended": "10.12.2.1121",
    "1.8-latest": "11.14.4.1577",
    "1.8-recommended": "11.14.4.1563",
    "1.8.8-latest": "11.15.0.1655",
    "1.8.9-latest": "11.15.1.1902",
    "1.8.9-recommended": "11.15.1.1722",
    "1.9-latest": "12.16.0.1942",
    "1.9-recommended": "12.16.1.1887",
    "1.9.4-latest": "12.17.0.1990",
    "1.9.4-recommended": "12.17.0.1976",
    "latest": "12.18.1.2014",
    "latest-1.7.10": "10.13.2.1343",
    "recommended": "12.18.1.2011"
  }
}

在这个网站上搜索了很多，我得到了以下代码：

dynamic json = JsonConvert.DeserializeObject<Dictionary<string, string>>(data);
foreach (KeyValuePair<string, string> entry in json["promos"])
{
    MessageBox.Show(entry.Key);
    MessageBox.Show(entry.Value);
} …

我想使用以下方法使用Newtonsoft.Json进行反射:

MyType object = JsonConvert.DeserializeObject<MyType>(jsonString);

这是我的方法不起作用(模糊匹配异常):

Type type = Type.GetType("MyType",false);
Type JSONCovert = typeof(JsonConvert);
MethodInfo deserializer = JSONCovert.GetMethod("DeserializeObject", new Type[] { typeof(String) });
deserializer = deserializer.MakeGenericMethod(type);
var o = deserializer.Invoke(null, new object[] { JsonString });

我需要将以下 Json 字符串转换为 DataTable。

{  
   "pnr":"1234567890",
   "train_num":"12311",
   "train_name":"HWH DLIKLK MAI",
   "doj":"23-12-2013",
   "from_station":
   {  
      "code":"DLI",
      "name":"Delhi"
   },
   "to_station":
   {  
      "code":"KLK",
      "name":"Kalka"
   }
}

在数据表中我需要显示

train_num
train_name
doj
from_station(name only)
to_station(name only)

到目前为止我所拥有的是，

public class Train
{
public string train_num { get; set; }
public string train_name { get; set; }
public string doj { get; set; }
public from_station from_station { get; set; }
public to_station to_station { get; set; }
}

public class from_station
{
public string code { get; …

我正在使用 Google Places API 服务（https://developers.google.com/places/web-service/）根据位置名称获取地点 ID。用户键入一些位置名称，就会出现相关建议，用户可以从中选择并获取地点 ID。我有一个要求，我需要三个文本框和一个按钮。用户输入地名、城市名和地址，然后单击按钮获取 placeId。目前，我没有看到基于多个参数获取地点 ID 的选项。我怎样才能做到这一点？

我正在尝试阅读我的JSON结果.

这是我的JsonResult

public class JsonResult
    {
    public string ResponseStatus;
    public string Status;
    public string Remarks;
    public string ErrorCode;
    public List<Data> data;    


    }
public class Data
{
    public string Status;
    public DateTime Date;
    public string Number;
    public string Amount;
    public string Balance;
    public string TranId;
    public string OPTId;
    public string RefId;

}

这是我的JSON结果

{
"ResponseStatus":"1",
"Status":"Success",
"Remarks":"Your recharge has been Pending.",
"ErrorCode":"3",
"Data":
    {
    "Status":"Pending",
    "Date":"2017-02-23T17:22:26.2001954+05:30",
    "Number":"9915933511",
    "Amount":10.0,
    "Balance":137.714,
    "TranId":"1126887",
    "OPTId":"","RefId":""
    }
}

这是我读取结果的代码

var result = JsonConvert.DeserializeObject<List<JsonResult>>(retPKT);

但获得例外..

无法将当前JSON对象(例如{"name":"value"})反序列化为类型'System.Collections.Generic.List`1 [JsonResult …
