startdateユーザー入力に応じて特定の日付範囲で見つかったデータとenddate、MVC を使用したグラフを表示したいと考えています。これを実現するには、json データが必要です。ユーザー入力に従ってjsonデータを取得できますが、使用できなかったためチャートが表示されませんurl:Machines/Parameter。

index.cshtml

<body>

 @using (Html.BeginForm("Parameter", "Machines", FormMethod.Post))
{
<div>

   Start Date:  <input type="datetime" id="start" name="start" />

   End Date: <input type="datetime" id="end" name="end" />

</div>
 <input type="submit" value="OK" /> 
Html.EndForm();}

MachinesController.cs

public ActionResult Index()
{
    return View();

}


public ActionResult Parameter(DateTime start, DateTime end)
{
    MachinesSql a = new MachinesSql();

    var data = Json(a.SqlAccessParameter(start, end), JsonRequestBehavior.AllowGet);

    return View(data);

}

モデル:Machines.cs

namespace DenemeReport.Models
{


public class Machines
{
    [Key]
    public int AutoKey;
    public string MachineGroup;
    public DateTime StartDate;
    public DateTime EndDate;
    public int Duration;

}
public class MachinesDBContext : DbContext
{
    public DbSet<Machines> Machine { get; set; }

}

 public List<Machines> SqlAccessParameter(DateTime startDate, DateTime endDate)
 {

    SqlConnection myConnection = new SqlConnection(connstr);
    myConnection.Open();
    SqlCommand myCommand = new SqlCommand("DateRange",myConnection);
    myCommand.CommandType = CommandType.StoredProcedure;
    myCommand.Parameters.Add("@SP_startDate", SqlDbType.DateTime).Value =startDate;
    myCommand.Parameters.Add("@SP_endDate", SqlDbType.DateTime).Value = endDate;

    SqlDataAdapter dataAdapter = new SqlDataAdapter();
    myCommand.ExecuteNonQuery();
    dataAdapter.SelectCommand = myCommand;

    DataSet dSet = new DataSet();
    dataAdapter.Fill(dSet);

    myConnection.Close();

    List<Machines> machinePost = new List<Machines>();
    foreach (DataRow row in dSet.Tables[0].Rows)
    {
        Machines mac = new Machines();
        mac.AutoKey = (int)row["AUTOKEY"];
        mac.MachineGroup = (string)row["MACHINEGROUP"];
        mac.Duration = (int)row["DURATION"];
        mac.StartDate = (DateTime)row["STARTTIME"];
        mac.EndDate = (DateTime)row["ENDTIME"];
        machinePost.Add(mac);
    }
    return machinePost;
}
