初学c#,由于项目需要操作Excel。网上搜索了一番,资料挺多。不过写的过于冗余,一上来就是一大断代码,看的头疼,
总结了下,不足的忘补充
考虑到兼容问题,针对office2003的操作
---必须的库 Microsoft.Office.Interop.Excel.dll (附件)
----代码中用到的类
using System; using System.Drawing; using System.Collections; using System.ComponentModel; using System.Data; using System.IO; using System.Text; using System.Windows; using System.Reflection; using System.Runtime.InteropServices; using Excel = Microsoft.Office.Interop.Excel;
创建一个新的Excel文件
(代码片段1)
Object missing = Missing.Value; Excel.Application m_objExcel = new Excel.Application(); Excel.Workbooks m_objWorkBooks = m_objExcel.Workbooks; Excel.Workbook m_objWorkBook = m_objWorkBooks.Add(true); Excel.Sheets m_objWorkSheets = m_objWorkBook.Sheets; ; Excel.Worksheet m_objWorkSheet = (Excel.Worksheet)m_objWorkSheets[1]; try { m_objExcel.Save("f:129.xls"); } catch (Exception e) { } finally { m_objWorkBooks.Close(); m_objExcel.Quit(); }
------ 操作单元格 单元格以横坐标和纵坐标进行导航
在代码一try{}catch(){}之前加入以下代码
(代码片段2)
m_objExcel.Cells[1, 1] = "建筑节能评估计算报告书";//第一行第一列文赋值
------合并单元格(在代码一try{}catch(){}之前加入以下代码)
m_objExcel.Cells[1, 1] = "建筑节能评估计算报告书"; Excel.Range range = m_objExcel.get_Range(m_objExcel.Cells[1, 1], m_objExcel.Cells[1, 10]); range.Merge(Type.Missing);//合并单元格
---操作字体大小,颜色,单元格背景色。边框颜色等(在代码一try{}catch(){}之前加入以下代码)
m_objExcel.Cells[1, 1] = "建筑节能评估计算报告书"; Excel.Range range = m_objExcel.get_Range(m_objExcel.Cells[1, 1], m_objExcel.Cells[1, 10]); range.Merge(Type.Missing);//合并单元格 range.Font.Size = 25;//字号 range.HorizontalAlignment = Excel.Constants.xlCenter; //居中对齐 range.Font.Bold = 17;//字体大小 // range.Borders.LineStyle = Excel.XlLineStyle.xlContinuous;//边框 // range.Borders.Color = ColorTranslator.ToOle(Color.Red);//边框颜色 //range.Interior.ColorIndex = 34;背景色

如果Excel格式固定,只是数据行数变动的话,可直接输出成xml的文本格式。
