在Excel中追加三列

我将数据从一个位置复制到另一个位置，并能够读取和打印所有值。 但是不能在Excel文件中附加列。 我需要在开始时追加三列（例如：“A”）。

private void btnUpload_Click(object sender, RoutedEventArgs e) { ApplicationClass app = new ApplicationClass(); Workbook book = null; Worksheet sheet = null; Range range = null; try { app.Visible = false; app.ScreenUpdating = false; app.DisplayAlerts = false; book = app.Workbooks.Open(@"C:\Windows\Temp\" + FileName, Missing.Value, Missing.Value, Missing.Value , Missing.Value, Missing.Value, Missing.Value, Missing.Value , Missing.Value, Missing.Value, Missing.Value, Missing.Value , Missing.Value, Missing.Value, Missing.Value); sheet = (Worksheet)book.Worksheets[1]; // get a range to work with range = sheet.get_Range("A1", Missing.Value); // get the end of values to the right (will stop at the first empty cell) range = range.get_End(XlDirection.xlToRight); // get the end of values toward the bottom, looking in the last column (will stop at first empty cell) range = range.get_End(XlDirection.xlDown); // get the address of the bottom, right cell string downAddress = range.get_Address( false, false, XlReferenceStyle.xlA1, Type.Missing, Type.Missing); // Get the range, then values from a1 range = sheet.get_Range("A1", downAddress); object[,] values = (object[,])range.Value2; // Value2 is a two dimenial array dime one = row, dime two = column. Console.WriteLine("Col Count: " + values.GetLength(1).ToString()); Console.WriteLine("Row Count: " + values.GetLength(0).ToString()); Microsoft.Office.Interop.Excel.Range oRng = sheet.Range["A1"]; oRng.EntireColumn.Insert(Microsoft.Office.Interop.Excel.XlInsertShiftDirection.xlShiftToRight, Microsoft.Office.Interop.Excel.XlInsertFormatOrigin.xlFormatFromRightOrBelow); oRng = sheet.Range["A1"]; oRng.Value2 = "Discount"; Microsoft.Office.Interop.Excel.Range oRng = sheet.Range["B1"]; oRng.EntireColumn.Insert(Microsoft.Office.Interop.Excel.XlInsertShiftDirection.xlShiftToRight, Microsoft.Office.Interop.Excel.XlInsertFormatOrigin.xlFormatFromRightOrBelow); oRng = sheet.Range["B1"]; oRng.Value2 = "NOTHING"; Microsoft.Office.Interop.Excel.Range oRng = sheet.Range["C1"]; oRng.EntireColumn.Insert(Microsoft.Office.Interop.Excel.XlInsertShiftDirection.xlShiftToRight, Microsoft.Office.Interop.Excel.XlInsertFormatOrigin.xlFormatFromRightOrBelow); oRng = sheet.Range["C1"]; oRng.Value2 = "HELLO"; } catch (Exception k) { Console.WriteLine(k); } finally { range = null; sheet = null; if (book != null) book.Close(false, Missing.Value, Missing.Value); book = null; if (app != null) app.Quit(); app = null; MessageBox.Show("File Uploaded Successfully. Please Wait...!"); } }

你只需要设置单元格的值。 不要使用“A1”作为单元格，因为您需要列号：A是第一个字母，所以它需要是第一列，B是第二个字母，需要是第二列等。在下面的代码中，您可以看到如何正确地做到这一点：

  Excel.Application app = new Excel.Application(); Excel.Workbooks workbooks = app.Workbooks; string filename = @"yourFilename"; workbooks.Open(filename); Excel.Workbook workbook = workbooks.Item[1]; Excel.Sheets worksheets = workbook.Worksheets; Excel.Worksheet worksheet = worksheets.Item[1]; Excel.Range cells = worksheet.UsedRange; cells[1, 2] = "Hello";//Set value for row 1 and column 2 (A1) cells[1, 3] = "World";//Set value for row 1 and column 3 (B1) workbook.Save();//Save Excel-File app.Quit(); Console.ReadKey();
