我有以下几点 stored-procedure 在一个 controller :

var insert_query = entities.Database.SqlQuery<Call_Info>("exec [dbo].[insert_call_info] @call_id, @user_id, @call_arrive, @call_end, @info", 
                    new SqlParameter("call_id", call_id),
                    new SqlParameter("user_id", u_id),
                    new SqlParameter("call_arrive", call_arrive),
                    new SqlParameter("call_end", call_end),
                    new SqlParameter("info", info)
                    ).ToList();

我正试着接通 POSTMAN 我得到以下错误：

"ExceptionMessage": "The data reader is incompatible with the specified 'EMSMVCModel.Call_Info'. A member of the type, 'call_id', does not have a corresponding column in the data reader with the same name.",
``` `Call_info.cs` 文件具有以下代码：

namespace EMSMVC.Models
{
using System;
using System.Collections.Generic;

public partial class Call_Info
{
    public int call_info_id { get; set; }
    public int call_id { get; set; }
    public string user_id { get; set; }
    public Nullable<System.DateTime> call_arrive { get; set; }
    public Nullable<System.DateTime> call_end { get; set; }
    public string info { get; set; }

    public virtual AspNetUser AspNetUser { get; set; }
    public virtual Call Call { get; set; }
}

}

call\u info表如下所示。 `call_info_id` 是一个自动递增字段，因此我不会通过存储过程添加值。

/******Object: Table [dbo].[Call_Info] Script Date: 25/5/2020 12:29:43 μ.μ.******/

我有 `stored-procedure` . 

GET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO

ALTER PROCEDURE [dbo].[insert_call_info]
-- Add the parameters for the stored procedure here
@call_id int,
@user_id nvarchar(128),

@call_end datetime,
@info nvarchar(255)
AS
BEGIN
SET FMTONLY OFF
-- SET NOCOUNT ON added to prevent extra result sets from
-- interfering with SELECT statements.
SET NOCOUNT ON;

INSERT INTO Call_info (call_id, user_id, call_arrive, call_end, info) VALUES (@call_id, @user_id, @call_arrive, @call_end, @info);
SELECT SCOPE_IDENTITY() AS call_info_id;

SET FMTONLY ON
