我正在尝试将一系列单元格从一个工作簿复制到另一个工作簿,它可以正常工作,但是当我尝试通过转置使用SaveAs函数时,它给了我一个错误:
System.Reflection.TargetInvocationException:“调用目标已抛出异常。”
内部异常。 COMException:Range类的PasteSpecial方法失败
这是我的代码:
private void CopyTranspose(string rawFile, string tempFile, string dataFile, string oldCells, string newCells)
{
try
{
object missing = Type.Missing;
//Copying data
Excel.Application oldApp = new Excel.Application();
oldApp.Application.DisplayAlerts = false;
oldApp.Application.Visible = false;
oldApp.Application.DisplayAlerts = false;
Excel.Workbook oldWorkBook = oldApp.Workbooks.Open(rawFile);
Excel.Worksheet oldWorkSheet = oldWorkBook.Worksheets.get_Item(1);
Excel.Range oldRange = oldWorkSheet.Range[oldCells];
oldRange.Copy(Type.Missing);
//Pasting data
Excel.Application newApp = new Excel.Application();
Excel.Workbook newWorkBook = newApp.Workbooks.Open(tempFile, 0, false);
newApp.Application.DisplayAlerts = false;
newApp.Application.Visible = false;
newApp.Application.DisplayAlerts = false;
Excel.Worksheet newWorkSheet = newWorkBook.Worksheets.get_Item(1);
Excel.Range newRange = newWorkSheet.Range[newCells];
newRange.Select();
newWorkSheet.Paste(Type.Missing, Type.Missing); //This line works but it doesn't do the transpose
newRange.PasteSpecial(Excel.XlPasteType.xlPasteValues,
Excel.XlPasteSpecialOperation.xlPasteSpecialOperationNone, true, true); //this line does the transpose but it fails
oldWorkBook.Close(false, null, null);
oldApp.Quit();
//Saving File
newWorkBook.SaveAs(dataFile, missing, missing, missing, missing, false);
newWorkBook.Close(false, null, null);
newApp.Quit();
}
catch (Exception ex) { Console.WriteLine(ex.Message); Console.ReadLine(); }
}
这是输出窗口上的例外:
抛出异常:mscorlib.dll中的'System.Runtime.InteropServices.COMException' Range类的PasteSpecial方法失败
任何帮助将不胜感激,我不仅在寻找解决方案,而且还了解我的代码有什么问题,谢谢!
