Excel格式行

我将创build一个Excel文件，其中包含一个姓名，一个date和一个“我的”私人跑比赛的代码。

它工作正常，但看起来不是很好。 如何格式化单元格以读取插入date和文本？ 名称和内容根本无法读取

Excel.Application _xlApp = new Excel.Application(); Excel.Workbook _xlWorkBook; Excel.Worksheet _xlWorkSheet; object misValue = System.Reflection.Missing.Value; internal void CreateExcelFile(string writePath) { this.CreateHeader(); this.AddContent(); this.SaveFile(writePath); } private void CreateHeader() { _xlWorkBook = _xlApp.Workbooks.Add(misValue); _xlWorkSheet = (Excel.Worksheet)_xlWorkBook.Worksheets.get_Item(1); _xlWorkSheet.Cells[1, ExcelObject.SAMNAME] = "SAM_NAME"; _xlWorkSheet.Cells[1, ExcelObject.DATE] = "Date"; _xlWorkSheet.Cells[1, ExcelObject.CODE] = "Code"; FormatCells(_xlWorkSheet.Cells.Borders); } private void AddContent() { int i = 1; ++i; _xlWorkSheet.Cells[i, ExcelObject.Date] = DateTime.Now.ToString("yyyyMMdd_HHmmss"); _xlWorkSheet.Cells[i, ExcelObject.SAMNAME] = "Julek"; } private void FormatCells(Excel.Borders _borders) { _borders[Excel.XlBordersIndex.xlEdgeLeft].LineStyle = Excel.XlLineStyle.xlContinuous; _borders[Excel.XlBordersIndex.xlEdgeRight].LineStyle = Excel.XlLineStyle.xlContinuous; _borders[Excel.XlBordersIndex.xlEdgeTop].LineStyle = Excel.XlLineStyle.xlContinuous; _borders[Excel.XlBordersIndex.xlEdgeBottom].LineStyle = Excel.XlLineStyle.xlContinuous; _borders.Color = ConsoleColor.Black; } private void SaveFile(string writePath) { string fileName = string.Format("{0}_{1}.xls","SampleFile", DateTime.Now.ToString("yyyyMMdd_HHmmss")); _xlWorkBook.SaveAs(Path.Combine(writePath, fileName), Excel.XlFileFormat.xlWorkbookNormal, misValue, misValue, misValue, misValue, Excel.XlSaveAsAccessMode.xlExclusive, misValue, misValue, misValue, misValue, misValue); _xlWorkBook.Close(true, misValue, misValue); _xlApp.Quit(); ReleaseObject(_xlWorkSheet); ReleaseObject(_xlWorkBook); ReleaseObject(_xlApp); } private void ReleaseObject(object obj) { try { System.Runtime.InteropServices.Marshal.ReleaseComObject(obj); obj = null; } catch (Exception) { throw; } finally { GC.Collect(); } } 

Answer 1

指定整列的格式，并使用ToOADate()方法而不是.ToString("yyyyMMdd_HHmmss") ：

 // get the date cell Range rg = _xlWorkSheet.Cells[ExcelObject.DATE, ExcelObject.DATE]; // specify the format for the whole column rg.EntireColumn.NumberFormat = @"yyyyMMdd\_HHmmss"; // ... // write the current date _xlWorkSheet.Cells[i, ExcelObject.DATE] = DateTime.Now.ToOADate(); 

我已经将yyyyMMdd_HHmmss的格式更改为yyyyMMdd\_HHmmss ，因为Excel会将_转换为空格，并保持下划线原样。

列的宽度可以以这种方式自动改变（在编辑结束时调用这个方法）：

 rg.EntireColumn.AutoFit(); 

插入所有数据时，最后应该调用AutoFit方法。 当它被调用时它只改变一次宽度，但不是连续的。
