將數據發送到SQL Server在此代碼創建一個SqlConnection到數據庫和HTTP Web服務來獲取JSON數據，但未能將數據轉儲到SQL服務器，也是我的控制檯窗口不會保持打開狀態以逐行調試程序我無法讀取，並通過控制檯應用程序

爲了調試，你是否設置了一個斷點？ –

是的，我設置了斷點，但控制檯窗口立即關閉，不顯示我的輸出？ –

您的Main()方法爲空。它是console app，您應該使用Main()而不是Page_Load()事件。將Page_Load()中的所有代碼放在Main()之內並刪除Page_Load()。

此外，您還應該製作所有字段，屬性和方法static，因爲您不會創建任何實例。

改變這一行：

public void Page_Load(object sender, EventArgs e)

本：

public void Start() // or any other name

和Main()應該是：

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

    obj.Start(); 
}

編輯：

你的代碼應該是：

對不起，我無法得到它我已經改變了Page_Load（object sender，EventArgs e）public void Start（），但問題仍然是相同的數據不會在sql –

@ R-T，你改變'Main'方法嗎？ –

是，這是程序'c：\ Users \ Administrator \ AppData \ Local \ Temporary Projects \ JSONARECHESTRA \ obj \ Debug \ JSONARECHESTRA.exe'不包含適用於入口點的靜態'Main'方法的錯誤 –

using System.Collections.Generic;

using System.Text; 
using Newtonsoft.Json.Linq; 
using System.Data.SqlClient; 
using System.Data; 
using HttpWebRequestResponse; 

namespace JSONARECHESTRA 
{ 
class Class1{ 


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

     obj.Start(); 
    } 

    private void Start() 
    { 
     Console.WriteLine("It is Start() method"); 
    } 




     public SqlConnection con = new SqlConnection(@"server=TNGSRV;database=astha;uid=sa;[email protected];MultipleActiveResultSets=True"); 
     public SqlCommand cmd; 
     public SqlDataReader dr1 ;

     { 
      if (con.State == ConnectionState.Closed)

     public void executeNonQuery(string query) 
     { 
      CONNECTION(); 
      cmd = new SqlCommand(query, con); 
      cmd.ExecuteNonQuery(); 
     } 
    } 
     public class user 

     {

     httpWebRequest.ContentType = "application/json"; 
     httpWebRequest.Method = "POST"; 

     using (var streamWriter = new System.IO.StreamWriter(httpWebRequest.GetRequestStream())) 
     { 
      string json = "{\"Username\":\"wave\"}"; 

      streamWriter.Write(json); 
      streamWriter.Flush(); 
      streamWriter.Close(); 
     } 

     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 [astha].[dbo].[TEST6] (datet) VALUES ('" + datetime + "');"; 
       cs.executeNonQuery(insert); 
       //return Page_Load; 
      } 
     } 
    } 


    public string json { get; set; } 





    } 
}

我已經做到了這一點，但得到同樣的問題仍數據不能在SQL打算以及控制檯窗口立刻關閉

你不用你的代碼調用方法。修改你的'Main'： 'static void Main（）{user.start（）; }' –

@羅馬可以請粘貼整個代碼與這些更改 –

@羅馬感謝噸它工作我欣賞你的幫助 –
