我在C#中写入Excel工作表时收到此错误。写完4,500行后会弹出一个错误:
System.Runtime.InteropServices.COMException(0x800AC472):来自HRESULT的异常:0x800AC472
在System.Dynamic.ComRuntimeHelpers.CheckThrowException(Int32 hresult,ExcepInfo& excepInfo,UInt32 argErr,String message)
在CallSite.Target(Closure,CallSite,ComObject,String)
在CallSite.Target(Closure,CallSite,Object,String)
在PaymentVarReadPDFMurfreesboro.ConvertPdfToExcel.writeToExcel(String filePath)
以下是打开并写入excel的代码。
public void writeToExcel(string filePath)
{
try
{
ExcelUse.Application excel = new ExcelUse.Application();
excel.Visible = true;
excel.DisplayAlerts = false;
ExcelUse.Workbook wb = excel.Workbooks.Open(filePath);
ExcelUse.Worksheet sh2 = wb.Worksheets.get_Item("Sheet1");
for (int i = 2; i <= finalList.Count+1; i++)
{
sh2.Cells[i, "A"].Value2 = finalList[i-2].ToString().Substring(33, 8);
sh2.Cells[i, "B"].Value2 = finalList[i-2].ToString().Substring(44, 7);
sh2.Cells[i, "C"].Value2 = finalList[i-2].ToString().Substring(117, 7);
}
wb.Save();
wb.Close(true);
excel.Quit();
}
catch (Exception e)
{
Console.WriteLine(e.ToString());
}
}
我之前使用过此代码来写入Excel工作表。但由于某种原因,它无法正常工作。我认为它与它写的行数有关。
