EPPlus excell read IndexOutOfRangeException

Question

我想從excell（.xlsx或.xls）文件讀取數據 我正在使用EPPlus ，但它給出了錯誤IndexOutOfRangeException：工作表位置超出範圍。 在這一行

OfficeOpenXml.ExcelWorksheet workSheet = package.Workbook.Worksheets[0]; 

這裏是我的一切code.Here是redad（http://yazilimsozluk.com/a.xlsx） .Are那裏爲EXCELL任何解決方案閱讀與工作的.xlsx和.xls的EXCELL文件我EXCELL文件？

if (Request != null) { 
    HttpPostedFileBase file = Request.Files["UploadedFile"]; 
    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 existingFile = new System.IO.FileInfo(fileName); 
    var package = new OfficeOpenXml.ExcelPackage(existingFile); 

    OfficeOpenXml.ExcelWorksheet workSheet = package.Workbook.Worksheets[0]; 

    for (int i = workSheet.Dimension.Start.Column; i <= workSheet.Dimension.End.Column; i++) { 
     for (int j = workSheet.Dimension.Start.Row; j <= workSheet.Dimension.End.Row; j++) { 
     object cellValue = workSheet.Cells[i, j].Value; 
     } 
    } 

    } 
} 

Answer 1

首先，EPPlus無法處理.xls文件。看到這個答案：

Error when trying to read an .xls file using EPPlus

示例代碼讀取文件：

var package = new ExcelPackage(new FileInfo("sample.xlsx")); 

ExcelWorksheet workSheet = package.Workbook.Worksheets.FirstOrDefault(); 

for (int i = workSheet.Dimension.Start.Column; 
     i <= workSheet.Dimension.End.Column; 
     i++) 
{ 
    for (int j = workSheet.Dimension.Start.Row; 
      j <= workSheet.Dimension.End.Row; 
      j++) 
    { 
     object cellValue = workSheet.Cells[i, j].Value; 
    } 
}
