mvc NPOI導入讀取Excel文件

后台方法：

public ActionResult ExcelUploadSubmit()
{
HttpPostedFileBase excelFile = Request.Files["excelFile"]; //取到上傳域
int count = 0;
if (null != excelFile)
{
string fileName = Path.GetFileName(excelFile.FileName); //取到文件的名稱
if (fileName.Equals("") || null == fileName)
{ //沒有選擇文件就上傳的話，則跳回到上傳頁面
return View("ZQ");
}
if (System.IO.Directory.Exists(Server.MapPath("upload")) == false)//如果不存在就創建file文件夾
{
System.IO.Directory.CreateDirectory(Server.MapPath("upload"));
}
string serverpath = Server.MapPath("/"); //獲取文件根目錄
string filePath = Path.Combine(HttpContext.Server.MapPath(@"\upload\"), Path.GetFileName(fileName));//合並得到完整的文件路徑

excelFile.SaveAs(serverpath + @"\upload\" + fileName); //保存上傳文件到服務器
DataTable dt = new DataTable();
dt.Columns.Add("Name", Type.GetType("System.String"));
dt.Columns.Add("Tel", Type.GetType("System.String"));
FileStream inputStream = new FileStream(serverpath + @"\upload\" + fileName, FileMode.Open);
HSSFWorkbook workbook = new HSSFWorkbook(inputStream); //解析上傳的Excel
HSSFSheet sheet = workbook.GetSheetAt(0) as HSSFSheet;
int rowNum = sheet.PhysicalNumberOfRows;
for (int i = 0; i < rowNum; i++)
{
HSSFRow row = sheet.GetRow(i) as HSSFRow;
int cellNum = row.PhysicalNumberOfCells;

DataRow newRow = dt.NewRow(); //DataTable創建新行
for (int j = 0; j < cellNum; j++)
{
HSSFCell cell = row.GetCell(j) as HSSFCell;
if (cell.CellType == CellType.Numeric)
{
newRow[j] = cell.NumericCellValue; //給新建的行加列
}
else
{
newRow[j] = cell.StringCellValue;
}
}
dt.Rows.Add(newRow); //新建的行加入到DataTable中
}
if (dt.Rows.Count > 0)
{
List<string> send = new List<string>();
StringBuilder sb = new StringBuilder();
foreach (DataRow dr in dt.Rows)
{
string name = dr["Name"].ToString();
string tel = dr["Tel"].ToString();
if (string.IsNullOrWhiteSpace(name) || string.IsNullOrWhiteSpace(tel))
