使用MVC篩選Excel輸出3

我想篩選發送到Excel文件的行。我已經能夠弄清楚如何將行數據導出爲excel，但是現在我需要將過濾的數據發送到excel表格，因爲我添加了一個版本下拉菜單。發生什麼事是我選擇我想從下拉列表中看到的版本。使用MVC篩選Excel輸出3

Ex。版本是12.1。

該視圖將僅返回與其關聯的版本號爲12.1的數據。現在，當我想要下載Excel文件中的過濾行時。我按下下載excel文件按鈕，它將打開excel文件中的文件，除非它帶來所有行而不是過濾行。我認爲我所要做的只是將相應的viewbag和viewdata變量添加到調用中，並且它會工作，沒有這樣的運氣，它仍然不斷地帶來每一行。你們可以看看我的代碼，並幫我弄清楚我做錯了什麼嗎？我已經發布了下面的代碼，請讓我知道如果您需要更多信息以更好地診斷，我會經常檢查回來！謝謝你的幫助！

Excel的控制器

[Authorize] 
     public ActionResult PaExcelOutput(string sortField, string currentFilter, string searchString, int? page, string VERS) 
     { 

      int pageNumber = (page ?? 1); // start page number 

      var PaExcel = from P in db.iamp_mapping 
          select P; 


      ViewBag.CurrentField = sortField = String.IsNullOrEmpty(sortField) ? "IAMP_PK" : sortField; // Provides the field to sort 
      ViewBag.CurrentFilter = searchString; // Provides the view with the current filter string 

      ViewData["SelectedVersion"] = VERS; 
      ViewData["currentFilter"] = currentFilter; 
      ViewData["VERS"] = new SelectList(PaExcel.Select(x => x.VERSION).Distinct()); 

      if (!String.IsNullOrEmpty(VERS)) 
      { 
       PaExcel = PaExcel.Where(p => p.VERSION.ToUpper().Contains(VERS)); 
      } 

      if (Request.HttpMethod == "GET") 
      { 
       searchString = currentFilter; //sets the currentFilter equal to Searchstring 
      } 

      else 
      { 
       page = 1;     // defaults to page 1 
      } 




      return View(PaExcel); 
     }

輸出到Excel查看

@model IEnumerable<DBFirstMVC.Models.iamp_mapping> 

<!--This is what the MVC uses to output the correct rows to Excel -->

    Layout = null; 
    Response.AddHeader("Content-Type", "application/vnd.ms-excel");

好，我知道我剛剛在一小時前發佈了這個問題，但我想通了，希望其他人會發現這個答案有幫助，如果他們有同樣的問題。我的excel調用的問題是，它有很多變量。

行動鏈接下載按鈕，看起來像在此之前

<div class="righty"> 
@Html.ActionLink("Download in Excel Format", "PaExcelOutput", "Pa", new { VERS = ViewBag.SelectedVersion, currentFilter = ViewBag.currentFilter, sortOrder = ViewBag.CurrentSort, @class = "button1" }) 

</div>

我改成了這個

<div class="righty"> 

@Html.ActionLink("Download in Excel Format", "PaExcelOutput", new { VERS = ViewBag.SelectedVersion, currentFilter = ViewBag.currentFilter, sortOrder = ViewBag.CurrentSort }, new { @class = "button1" }) 

</div>

通過從句子移除"Pa"我刪除了額外的變量，是造成viewbags不能將變量傳遞給excel輸出。

的ActionLink的方法應該如下所示

ActionLink(HtmlHelper, String, String, Object, Object)

現在我知道了......，知道是成功的一半！

試試這個代碼中使用互操作曾爲 Excel中....

代碼：

private System.Data.DataTable GetExcelData(string fileName) 
     { 
      Application excelApp = null; 
      Workbook excelWorkBook = null; 
      Worksheet excelSheet;

      try
