Question

我正在研究一个类项目，我正在尝试实现一个简单的工资单流程，用户输入开始日期和结束日期然后点击获取报告，然后下载Excel文件。我还是ASP.NET MVC的新手，我发现它下载了一些代码而不是我期待的代码。

这是我的简单观点

@model IEnumerable<RazorCab.Models.Payroll>
@{
    ViewBag.Title = "Index";

   string strMessage = ViewBag.Message; 
}

<h2>Payroll</h2>
@using (Html.BeginForm("Index", "Payrolls", FormMethod.Get))
{
 <table>
<tr>
      <td>Select Dates:</td>
      <td><input type="date" name="dteStartDate" id="dteStartDate"       placeholder="YYYY/MM/DD" /></td>
    <td>To</td>
    <td><input type="date" name="dteEndDate" id="dteEndDate" placeholder="YYYY/MM/DD" /></td>
</tr>
<tr>
    <td><input type="submit" value="Get Report" /></td>
</tr>
@if (strMessage != "")
{
 <tr>
<td><p>@strMessage</p></td>
</tr>
}
</table>
}

这是我的控制器

public class PayrollsController : Controller
{
    private RazorCab02Entities db = new RazorCab02Entities();  

    // GET: Payrolls
    public ActionResult Index(DateTime? dteStartDate, DateTime? dteEndDate)
    {
        if (dteStartDate != null && dteEndDate != null)
        {
            var @StartDate = new SqlParameter("@StartDate", dteEndDate);
            var @EndDate = new SqlParameter("@EndDate", dteEndDate);

            string query = "SELECT E.EMPLID, E.FIRSTNAME, E.LASTNAME, E.WAGE, H.CLOCKINTIME, H.COCKOUTTIME, DATEDIFF(HOUR, H.CLOCKINTIME, H.CLOCKOUTTIME) AS HOURS_WORKED, E.WAGE * DATEDIFF(HOUR, H.CLOCKINTIME, H.CLOCKOUTTIME) AS DAILY_EARNINGS "
                + "FROM EMPLOYEE E "
                + "JOIN HOURLYWAGEMGMT H "
                + "ON H.EMPLID = E.EMPLID "
                + "WHERE E.POSITION = 'Driver' "
                + "AND H.CLOCKINDATE BETWEEN @StartDate AND @EndDate "
                + "AND H.CLOCKOUTDATE BETWEEN @StartDate AND @EndDate ";

            var grid = new GridView();
            grid.DataSource = query;

            Response.ClearContent();
            Response.Buffer = true;
            Response.AddHeader("content-diposition", "attachment; filename=PayrollExcelFile.xls");
            Response.ContentType = "application/ms-excel";
            Response.Charset = "";
            StringWriter sw = new StringWriter();
            HtmlTextWriter htw = new HtmlTextWriter(sw);

            grid.RenderControl(htw);

            Response.Output.Write(sw.ToString());
            Response.Flush();
            Response.End();

            return View();
        }
        else
        {
            return View();
        }
    }
}

这是我的模特：

public class Payroll
{
    public int EmplID { get; set; }
    public string FirstName { get; set; }
    public string LastName { get; set; }
    public decimal Wage { get; set; }
    public DateTime ClockInTime { get; set; }
    public DateTime? ClockOutTime { get; set; }
    public int HoursWorked { get; set; }
    public decimal DailyEarnings { get; set; }
}

我将非常感谢任何帮助，我查看了控制器代码并且对于这样做的人来说它很好但我不确定我做错了什么。

Answer 1

我最终实现了Epplus，我删除了该代码，并在我的控制器中编写了这段代码，除了我的日期被扔到excel中的序列号之外，所有这些都是可行的，所以我猜这就是为什么我对日期的计算不起作用的原因。有谁知道如何正确制作我的日期格式？

 public ActionResult Index(DateTime? dteStartDate, DateTime? dteEndDate)
    {

        if (dteStartDate != null && dteEndDate != null)
           {

                //var @StartDate = new SqlParameter("@StartDate", dteEndDate);
               // var @EndDate = new SqlParameter("@EndDate", dteEndDate);


            string query = "SELECT E.EMPLID, E.FIRSTNAME, E.LASTNAME, E.WAGE, H.CLOCKINTIME, H.CLOCKOUTTIME, DATEDIFF(HOUR, H.CLOCKINTIME, H.CLOCKOUTTIME) AS HOURS_WORKED, E.WAGE * DATEDIFF(HOUR, H.CLOCKINTIME, H.CLOCKOUTTIME) AS DAILY_EARNINGS "
                + "FROM EMPLOYEE E "
                + "JOIN HOURLYWAGEMGMT H "
                + "ON H.EMPLID = E.EMPLID "
                + "WHERE E.POSITION = 'Driver' "
                + "AND H.CLOCKINDATE BETWEEN '" + dteStartDate + "' AND '" + dteEndDate + "' "
                + "AND H.CLOCKOUTDATE BETWEEN '" + dteStartDate + "' AND '" + dteEndDate + "' ";




            var data = db.Database.SqlQuery<Payroll>(query);
            var pck = new OfficeOpenXml.ExcelPackage();
            var ws = pck.Workbook.Worksheets.Add("Payroll");
            ws.Cells["A2"].LoadFromCollection(data, false);
            ws.Cells["A1"].Value = "EmployeeID";
            ws.Cells["B1"].Value = "FirstName";
            ws.Cells["C1"].Value = "LastName";
            ws.Cells["D1"].Value = "Wage";
            ws.Cells["E1"].Value = "ClockInTime";
            ws.Cells["F1"].Value = "ClockOutTime";
            ws.Cells["G1"].Value = "HoursWorked";
            ws.Cells["H1"].Value = "DailyEarnings";

            using (ExcelRange rng = ws.Cells["A1:H1"])
            {
                rng.Style.Font.Bold = true;
                rng.Style.Fill.PatternType = ExcelFillStyle.Solid;
                rng.Style.Fill.BackgroundColor.SetColor(System.Drawing.Color.FromArgb(79, 129, 189));
                rng.Style.Font.Color.SetColor(System.Drawing.Color.White);
            }
            Response.Clear();
            Response.ContentType = "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet";
            Response.AddHeader("content-disposition", "attachment;  filename=Payroll.xlsx");
            Response.BinaryWrite(pck.GetAsByteArray());


        Response.End();

        return View();

         }
        else
        {
          return View();
         }
    }
}

}

我想要一个基于mvc中的一些sql下载的Excel文件
