    class Class1
    {
        static void Main()
        { }

        public SqlConnection con =newSqlConnection(@"server=SERVE;database=DATABASE;uid=XX;password=XXXX;MultipleActiveResultSets=True");
        public SqlCommand cmd;
        public SqlDataReader dr1;

            cmd = new SqlCommand(query, con);
            cmd.ExecuteNonQuery();
        }
    }

    public class user
    {
        public void Page_Load(object sender, EventArgs e)
        {
            var httpWebRequest = (System.Net.HttpWebRequest)System.Net.WebRequest.Create("http:URL");
            httpWebRequest.ContentType = "application/json";

            var httpResponse = (System.Net.HttpWebResponse)httpWebRequest.GetResponse();

            using (var streamReader = new System.IO.StreamReader(httpResponse.GetResponseStream()))
            {
                var result = streamReader.ReadToEnd();
                JObject jObject = JObject.Parse(result);
                response = jObject["Rdata"][0].ToArray();
                JArray array = (JArray)jObject["Rdata"];

                for (int i = 0; i <= 3; i++)
                {
                    int Alert_Type = Convert.ToInt32((string)array[i]["Alert_Type"]);
                    DateTime datetime = Convert.ToDateTime((string)array[i]["Date_time"]);
                    string Location = Convert.ToString((string)array[i]["Location"]);
                    string Vehicle = Convert.ToString((string)array[i]["Vehicle"]);
                    Console.WriteLine(Vehicle);
                    Console.ReadKey();

                    Class1 cs = new Class1();
                    cs.CONNECTION();

                    string insert = "INSERT INTO [DATABASE].[dbo].[TEST6] (datet) VALUES ('" + datetime + "');";
                    cs.executeNonQuery(insert);
                    // return Page_Load;
                }
            }
        }

        public string json { get; set; }

        public JToken[] response { get; set; }
    }
}

在这段代码中，我为数据库和Http Web服务创建了一个SqlConnection来获取JSON数据但是无法将数据转储到SQL Server中，并且我的控制台窗口也没有保持打开状态来逐行调试程序< / p>

答案 0 :(得分：1)

您的Main()方法为空。它是console app，您应该使用Main()而不是Page_Load()事件。将Page_Load()中的所有代码放在Main()内并删除Page_Load()。

此外，您应该创建所有字段，属性和方法static，因为您不创建任何实例。

或

更改此行：

public void Page_Load(object sender, EventArgs e)

由此：

public void Start() // or any other name

和Main()应为：

static void Main()
{
    Class1 obj = new Class1();

    obj.Start();
}

修改

你的代码应该是：

using System;

                    string Vehicle = Convert.ToString((string)array[i]["Vehicle"]);
                    Console.WriteLine(Vehicle);
                    Console.ReadKey();

                    this.CONNECTION();

                    string insert = "INSERT INTO [DATABASE].[dbo].[TEST6] (datet) VALUES ('" + datetime + "');";
                    this.executeNonQuery(insert);

    }


    public string json { get; set; }





   }
}

我已经完成了这个但是得到同样的问题仍然数据不在sql以及控制台窗口立即关闭
