Excelシートがmvcで機能しないExcelシートをインポートするには

Question

mvcにExcelシートをエクスポートするためのコードが見つかりません。これを行う方法を示すことができるプロジェクトやサンプルコードを持つ人がいますか？

public class HomeController : Controller //home 
{ 
    // 
    // GET: /Home/ 

    [HttpGet] 
    public ActionResult Upload(FormCollection formCollection) { 
     if (Request != null) { 
      HttpPostedFileBase file = Request.Files["UploadedFile"]; //file 
      if ((file != null) && (file.ContentLength > 0) && !string.IsNullOrEmpty(file.FileName)) { 
       string fileName = file.FileName; //filename 
       string fileContentType = file.ContentType; 
       byte[] fileBytes = new byte[file.ContentLength]; 
       var data = file.InputStream.Read(fileBytes, 0, Convert.ToInt32(file.ContentLength)); 
       var usersList = new List<Users>(); 
       using (var package = new ExcelPackage(file.InputStream)) //stream 
       { 
        var currentSheet = package.Workbook.Worksheets; 
        var workSheet = currentSheet.First(); 
        var noOfCol = workSheet.Dimension.End.Column; 
        var noOfRow = workSheet.Dimension.End.Row; 
        for (int rowIterator = 2; rowIterator <= noOfRow; rowIterator++) { 
         var user = new Users(); 
         user.FirstName = workSheet.Cells[rowIterator, 1].Value.ToString(); 
         user.LastName = workSheet.Cells[rowIterator, 2].Value.ToString(); 
         usersList.Add(user); 
        } 
       } 
      } 
     } 
     return View("Index"); //return 
    } 
    public class Users { 
     public string FirstName { get; set; } //get set 
     public string LastName { get; set; } 
    } 
}

//レビューのコードの下に、あなたはそれを取ると、あなたの方法 それを使用することができますuはnugetをインストールする必要があり、 "ExcelPackage"

 public ActionResult UploadXls() 
    { 
     if (Request != null) 
     { 
      HttpPostedFileBase file = Request.Files["UploadedFile"]; 
      if (file != null && !file.FileName.Contains(".xl")) 
      { 
       TempData["description"] = "This file format is not supported, please use .xl or .xls formated file."; 
       //ModelState.AddModelError("File", "This file format is not supported"); 
       return RedirectToAction("PropertyInventory", "PropertyBo", new { id = propertyId }); 
      } 

      if ((file != null) && (file.ContentLength > 0) && !string.IsNullOrEmpty(file.FileName)) 
      { 
       string fileName = file.FileName; 
       string fileContentType = file.ContentType; 
       byte[] fileBytes = new byte[file.ContentLength]; 
       var data = file.InputStream.Read(fileBytes, 0, Convert.ToInt32(file.ContentLength)); 
       var PropertyIn = new List<InventoryModelView>(); 
       int idTemp = 0; 
       var alreadyExistInventoryList = new List<InventoryModelView>(); 

       using (var package = new ExcelPackage(file.InputStream)) 
       { 
        var currentSheet = package.Workbook.Worksheets; 
        var workSheet = currentSheet.First(); 
        var noOfCol = workSheet.Dimension.End.Column; 
        var noOfRow = workSheet.Dimension.End.Row; 
        for (int rowIterator = 2; rowIterator <= noOfRow; rowIterator++) 
        { 
         var inv = new PropertyInventory(); 

         inv.PropertyId = propertyId; 
         if (string.IsNullOrEmpty(workSheet.Cells[rowIterator, 1].Value.ToString())) 
         { 
          continue; 
         } 
         else 
         { 
          inv.UnitNo = workSheet.Cells[rowIterator, 1].Value.ToString(); 
         } 


        } 

       }     


      } 
     } 

     TempData["description"] = "Great! Excel upload successfully"; 
     return RedirectToAction("abcd", "bcad", new { id = propertyId, flag = 1 }); 

    }
