excel行數使用asp

Question

我想寫一個代碼來讀取excel來獲取行數和數據。我收到了一個例外，即excel被加密或處於只讀模式。

wb = xlApp.Workbooks.Open(srcFile, 0, false, 5, "", "", false, Excel.XlPlatform.xlWindows, "",true, false, 0, true, false, false); 

任何人都可以請在這裏提供一些幫助。

Answer 1

使用使用方法打開文件，該文件在其工作完成時也會處理處理對象。

可能是文件被打開與否，還通過 'FileShare.Read' 你打開文件readmode爲

using (FileStream fs = File.Open(<file-path>, FileMode.Open, FileAccess.Read, FileShare.Read)) 

檢查此鏈接

Open file ReadOnly

Exception in opening a file that is already open

Answer 2

使用

var workbook = 
     excelApp.Workbooks.Open(_mirrorFileName,Type.Missing,Type.Missing, Type.Missing, Type.Missing, 
      Type.Missing, Type.Missing, Type.Missing, Type.Missing, 
      Type.Missing, Type.Missing, Type.Missing, Type.Missing, 
      Type.Missing, Type.Missing); 

     var worksheet = (Worksheet)workbook.Worksheets[1]; 
     var rowCount = worksheet.UsedRange.Rows.Count; 

Answer 3

只是嘗試一下的參數值，並與您的參數值

它的工作比較適合我

xlApp = new Excel.Application(); 
      xlWorkBook = xlApp.Workbooks.Open(@"E:\LIQ.xlsx", 0, true, 5, "", "", true, Microsoft.Office.Interop.Excel.XlPlatform.xlWindows, "\t", false, false, 0, true, 1, 0);
