1、C#创建Excel文档。

2、下面的代码需要添加spire.doc.dll为依赖//创建一个workbook实例Workbook wb = new Workbook();//清除默认的工作表wb.Worksheets.Clear();//添加一个工作表并指定表名Worksheet sheet = wb.Worksheets.Add("职员表");//横向合并A1到G1的单元格sheet.Range["A1:G1"].Merge();//写入数据到A1单元格。

3、设置文字格式及对齐方式sheet.Range["A1"].Value = "环宇汽车公司员工基本情况登记表"; sheet.Range["A1"].HorizontalAlignment = HorizontalAlignType.Center;sheet.Range["A1"].VerticalAlignment = VerticalAlignType.Center;sheet.Range["A1"].Style.Font.IsBold = true;sheet.Range["A1"].Style.Font.Size = 13F;//设置第一行行高sheet.Rows[0].RowHeight = 30F;//创建一个DataTableDataTable dt = new DataTable();dt.Columns.Add("姓名");dt.Columns.Add("性别");dt.Columns.Add("出生日期");dt.Columns.Add("学历");dt.Columns.Add("联系电话");dt.Columns.Add("职务");dt.Columns.Add("工号");dt.Rows.Add("王伟", "男", "1990年2月10日", "本科", "13524756854", "销售","0054");dt.Rows.Add("李宁", "男", "1985年6月8日", "大专", "13259863247", "销售","0055");dt.Rows.Add("邓家佳", "女", "1989年11月25日", "本科", "13601540352", "销售","0029");dt.Rows.Add("杜平安", "男", "1978年4月16日", "中专", "13352014060", "保安","0036");dt.Rows.Add("唐静", "女", "1980年1月21日", "本科", "13635401489", "店长","0010");//将DataTable数据写入工作表sheet.InsertDataTable(dt, true, 2, 1, true);//设置该区域行高sheet.Range["A2:G7"].RowHeight = 15F;//设置第三列及第五列列宽sheet.Range["A2:G7"].Columns[2].ColumnWidth = 15F;sheet.Range["A2:G7"].Columns[4].ColumnWidth = 15F;//设置网格线样式及颜色sheet.Range["A2:G7"].BorderAround(LineStyleType.Medium);   sheet.Range["A2:G7"].BorderInside(LineStyleType.Thin);sheet.Range["A2:G2"].BorderAround(LineStyleType.Medium);sheet.Range["A2:G7"].Borders.KnownColor = ExcelColors.Black;//保存为.xlsx文件wb.SaveToFile("创建Excel.xlsx", FileFormat.Version2013);1. 创建一个Console Application, 添加COM选显卡中的Microsoft Excel 12.0 Object Library引用.2. 粘贴下面的源代码.using System;using Excel = Microsoft.Office.Interop.Excel;namespace CShartExcelTest{ class Program { static void Main(string[] args) { try { string[,] values = { {"Tom", "18", "Beijing", "13912345678"}, {"Jerry", "17", "Shanghai", "13687654321"} }; Excel.Application objApp; Excel._Workbook objBook; Excel.Workbooks objBooks; Excel.Sheets objSheets; Excel._Worksheet objSheet; Excel.Range range; // Instantiate Excel and start a new workbook. objApp = new Excel.Application(); objBooks = objApp.Workbooks; objBook = objBooks.Add(System.Reflection.Missing.Value); objSheets = objBook.Worksheets; objSheet = (Excel._Worksheet)objSheets.get_Item(1); //Get the range where the starting cell has the address range = objSheet.get_Range("A2", System.Reflection.Missing.Value); range = range.get_Resize(2, 4); range.set_Value(System.Reflection.Missing.Value, values); //Construct the header. objSheet.Cells[1, 1] = "Name"; objSheet.Cells[1, 2] = "Age"; objSheet.Cells[1, 3] = "HomeTown"; objSheet.Cells[1, 4] = "Mobile"; bool bSave = false; if (bSave) { //Return control of Excel to the user. objApp.Visible = true; objApp.UserControl = true; } else { objBook.SaveAs(@"c:empcsharp-Excel.xls", Excel.XlFileFormat.xlWorkbookNormal, System.Reflection.Missing.Value, System.Reflection.Missing.Value, System.Reflection.Missing.Value, System.Reflection.Missing.Value, Excel.XlSaveAsAccessMode.xlExclusive, System.Reflection.Missing.Value, System.Reflection.Missing.Value, System.Reflection.Missing.Value, System.Reflection.Missing.Value, System.Reflection.Missing.Value); objBook.Close(true, System.Reflection.Missing.Value, System.Reflection.Missing.Value); objApp.Quit(); releaseObject(objSheet); releaseObject(objBook); releaseObject(objApp); } } catch (Exception ex) { Console.WriteLine(ex.Message); } } private static void releaseObject(object obj) { try { System.Runtime.InteropServices.Marshal.ReleaseComObject(obj); obj = null; } catch (Exception ex) { obj = null; Console.WriteLine("Exception Occured while releasing object " + ex.ToString()); } finally { GC.Collect(); } } }}。
