| 一、添加引用 添加com组件（Microsoft Office 11.0 Object Library ）命名空间为Microsoft.Office.Interop.Excel 添加Excel.exe引用默认路径为C:\Program Files\Microsoft Office\OFFICE11\Excel.exe 二、Excel控制类 using System; using System.Collections.Generic; using System.Text; using System.Windows.Forms; using Excel = Microsoft.Office.Interop.Excel; namespace ExcelOperation { public class ExcelControl { private Excel.Application m_objExcel = null; private Excel.Workbooks m_objBooks = null;

if (TemplateFilePath.Equals(String.Empty)) { m_objBook = (Excel._Workbook)(m_objBooks.Add(m_objOpt)); } else { m_objBook = m_objBooks.Open(TemplateFilePath, m_objOpt, m_objOpt, m_objOpt, m_objOpt, m_objOpt, m_objOpt, m_objOpt, m_objOpt, m_objOpt, m_objOpt, m_objOpt, m_objOpt, m_objOpt, m_objOpt);

m_objRange = (Excel.Range)m_objSheet.Columns[DeleteColumnIndex, System.Reflection.Missing.Value]; m_objRange.EntireColumn.Delete(Excel.XlDirection.xlDown); } } } 三、Excel操作方法调用 1.插入图片和线调用 PictureInExcel ipt = new PictureInExcel(); ipt.Open(); //ipt.InsertPicture("B2", @"C:\"); //ipt.InsertPicture("B8", @"C:\", 1000, 800); ipt.InsertPicture("B2","F8", @"C:\",true); ipt.InsertLine("B9", "F15", true); ipt.InsertPicture("B16", "F22", @"C:\", false); ipt.InsertLine("B23", "F29", false); ipt.SaveFile(@"C:\ExcelTest.xls"); ipt.Dispose(); 2.删除行方法调用 PictureInExcel ipt = new PictureInExcel(); ipt.Open(@"C:\ExcelTest.xls"); ipt.DeleteRow(1,1); ipt.SaveFile(@"C:\ExcelTest.xls"); ipt.Dispose(); 3.删除列方法调用 PictureInExcel ipt = new PictureInExcel(); ipt.Open(@"C:\ExcelTest.xls"); ipt.DeleteColumn(1, 1); ipt.SaveFile(@"C:\ExcelTest.xls"); ipt.Dispose(); 四、参考资料 孟子E章的 《C#向Excel报表中插入图片的2种方法》等 本文来自CSDN博客，转载请标明出处：http://blog.csdn.net/wsxqaz/archive/2007/11/14/1883810.aspx |
