在C#windows应用程序中,我有许多excel工作簿,我想要的是将工作表从excel工作簿复制到单个工作簿.这是可能的,但我必须打开excel工作簿才能这样做.

        Excel.Application app = new Excel.Application();

        app.Visible = true;

        app.WindowState = XlWindowState.xlMinimized;

        app.Workbooks.Add("");
        app.Workbooks.Add(@"Path\WorkBook1.xlsx");
        app.Workbooks.Add(@"Path\WorkBook2.xlsx");

        for (int i = 2; i <= app.Workbooks.Count; i++)
        {
            int count = app.Workbooks[i].Worksheets.Count;

                    );

                sheet.Paste(Type.Missing, Type.Missing);

                sheet.Name = app.Workbooks[i].Worksheets[j].Name;
            }


        }

        app.DisplayAlerts = false;
        app.Workbooks[3].Close();
        app.Workbooks[2].Close();
        app.DisplayAlerts = true;

        Cursor = Cursors.Default;

        MessageBox.Show("Successfully Generated …
