将联系人导出到csv文件会自动将手机号码格式化为科学版本

进入我的项目时，将联系人导入到csv文件自动格式手机号码开始91科学。

例如手机号码input数据

919433454320

当科学格式移动没有进入CSV文件

9.194E + 11

格式化后的数字为小数点后0位

9194.3亿

使用Microsoft.Office.Interop.Excel.Application将联系人导出到我的项目中

这里的工作簿是我的代码

Microsoft.Office.Interop.Excel.Application app = new Microsoft.Office.Interop.Excel.Application(); app.Visible = false; Workbook wb = app.Workbooks.Add(); Worksheet ws = (Worksheet)wb.Worksheets.get_Item(1); object[,] rawData = new object[DataTable.Rows.Count + 1, DataTable.Columns.Count]; for (int col = 0; col < DataTable.Columns.Count; col++) { rawData[0, col] = DataTable.Columns[col].ColumnName; } for (int col = 0; col < DataTable.Columns.Count; col++) { for (int row = 0; row < DataTable.Rows.Count; row++) { rawData[row + 1, col] = DataTable.Rows[row].ItemArray[col]; } } string[] callchar = new string[] {"range of my excel sheet (eg from a to Bz"}; string excelRange = callchar[0] + "1:" + callchar[DataTable.Columns.Count - 1] + (DataTable.Rows.Count + 1).ToString(); Range r = ws.Cells.EntireColumn.NumberFormat; ws.get_Range(excelRange, Type.Missing).Value2 = rawData; wb.SaveAs(Filename: FilePath, FileFormat: XlFileFormat.xlCSVWindows, ReadOnlyRecommended: false); wb.Close(); app.Quit();

您可以使用后期绑定来导出数据：

  // try to open excel Thread.CurrentThread.CurrentCulture = new CultureInfo("en-US"); Type typeExcelApplication = Type.GetTypeFromProgID("Excel.Application"); if (typeExcelApplication == null) throw new Exception("Excel is not installed (Excel.Application is not found)"); object objExcelApplication = Activator.CreateInstance(typeExcelApplication); object objWorkBooks = objExcelApplication.GetType().InvokeMember("Workbooks", BindingFlags.GetProperty, null, objExcelApplication, null); object objWorkBook = objWorkBooks.GetType().InvokeMember("Add", BindingFlags.InvokeMethod, null, objWorkBooks, null); object objWorkSheet = objWorkBook.GetType().InvokeMember("ActiveSheet", BindingFlags.GetProperty, null, objWorkBook, null); // fill data (put object obj into cell [1,1]) objWorkSheet.GetType().InvokeMember("Cells", BindingFlags.SetProperty, null, objWorkSheet, new object[] { 1, 1, obj}); // display excel typeExcelApplication.InvokeMember("Visible", BindingFlags.SetProperty, null, objExcelApplication, new object[] { true }); Marshal.ReleaseComObject(objExcelApplication); 

Excel应该正确地处理types，所以如果你将obj作为一个string – 它不会试图从中得到一个数字（科学的）。
