  • C#实现向excel中插入行列,以及设置单元格合并居中效果

    插入空行:

    Microsoft.Office.Interop.Excel.Workbook xlsWorkbook;

    Microsoft.Office.Interop.Excel.Worksheet xlsSheet = xlsWorkbook.Worksheets[1];

    Microsoft.Office.Interop.Excel.Range xlsRow=(Microsoft.Office.Interop.Excel.Range)xlsSheet.Rows[3,MisValue];

    xlsRow.Insert(Microsoft.Office.Interop.Excel.xlShiftDown,MisValue);

    插入空列:

    Excel.Range xlsColumns = (Excel.Range)ws.Columns[index, Type.Missing];

                xlsColumns.Insert(Excel.XlInsertShiftDirection.xlShiftToRight, Type.Missing);

                string columnLetter = GetLetter(index - 1);
                ws.Cells[2, index] = txtBoxExpenseType.Text.Trim();
                Excel.Range newExpenseTypeRange = ws.get_Range(string.Format("{0}{1}", columnLetter, 2), string.Format("{0}{1}", columnLetter, 3));
                newExpenseTypeRange.MergeCells = true;
                newExpenseTypeRange.VerticalAlignment = Excel.XlVAlign.xlVAlignCenter;
                newExpenseTypeRange.HorizontalAlignment = Excel.XlVAlign.xlVAlignCenter;

    public static string GetLetter(int index)
            {
                if (index < 0) { throw new Exception("invalid parameter"); }

                List chars = new List();
                do
                {
                    if (chars.Count > 0) index--;
                    chars.Insert(0, ((char)(index % 26 + (int)'A')).ToString());
                    index = (int)((index - index % 26) / 26);
                } while (index > 0);

                return String.Join(string.Empty, chars.ToArray());
            }
