1前言
这两天由于某种需要,研究了一下.NET中对Excel的互操作,之前主要是直接通过第三方的组件等方式来操作的Excel,这次仔细的研究了一下,对常用的Excel操作需求做了一个简单的总结,比如创建Excel,设置单元格样式,合并单元格,导入内存中的DataTable,插入图片、图表等。在此基础上借助于Microsoft.Office.Interop.Excel对这些操作进行了封装最终形成了ExcelHandler类。本文主要对自己封装的这个类进行简单的举例说明,关于此类的完整代码参见第三部分。
注意:对于命名空间Microsoft.Office.Interop.Excel,使用之前需要引用COM:Microsoft Office 11.0 Object Library(office 2003 )或者Microsoft Office 12.0 Object Library(office 2007 ),如果引用列表中没有,需要自行添加 X:Program Files/Microsoft Office/OFFICE[11|12]/EXCEL.EXE的引用。如果已经安装VSTO(Visual Studio Tools For Office),亦可直接添加对X:\Program Files\Microsoft Visual Studio [9.0|8.0]\Visual Studio Tools for Office\PIA\Office[11|12]\Microsoft.Office.Interop.Excel.dll的引用。
2ExcelHandler类举例说明
为了展示该类的使用方法,新建了一个WinForm的测试项目进行测试,项目名称可自定,添加对ExcelHandler的dll的引用。所有测试代码均放在窗体的一个按钮单击事件的处理方法中。
2.1创建Excel文件
- /// <summary>
- /// 测试ExcelHandler类
- /// </summary>
- /// <param name="sender"></param>
- /// <param name="e"></param>
- private void buttonTest_Click(object sender, EventArgs e)
- {
- string excelFilePath = string.Format("{0}Excel-{1}.xls", AppDomain.CurrentDomain.BaseDirectory, DateTime.Now.ToString("yyyyMMddHHmmss"));
- using (ExcelHandler handler = new ExcelHandler(excelFilePath, true))
- {
- handler.OpenOrCreate();
- MessageBox.Show("创建Excel成功!");
- handler.Save();
- MessageBox.Show(string.Format("保存Excel成功!Excel路径:{0}", excelFilePath));
- }
- }
点击按钮执行后,可以看到在Debug目录下多了一个Excel文件
此文件的完整路径为:F:\My Projects\Tanging.DataVisualization\Tanging.DataVisualization\bin\Debug\Excel-20100314181502.xls。
注意:之后的例子的Excel的文件的路径需要为你自己创建的Excel的相应路径。
下面将举例说明对此Excel文件进行操作。
2.2创建自己的工作表Worksheet
- private void buttonTest_Click(object sender, EventArgs e)
- {
- string excelFilePath = string.Format("{0}Excel-20100314181502.xls", AppDomain.CurrentDomain.BaseDirectory);
- using (ExcelHandler handler = new ExcelHandler(excelFilePath, false))//设置第二个参数为false表示直接打开现有的Excel文档
- {
- handler.OpenOrCreate();
- //创建一个Worksheet
- Worksheet sheet = handler.AddWorksheet("TestSheet");
- //删除除TestSheet之外的其余Worksheet
- handler.DeleteWorksheetExcept(sheet);
- handler.Save();
- }
- }
再次打开创建的Excel,可以看到新建的Worksheet
2.3单元格、Range等的操作
下面设置A1到E5的单元格样式,并且设置单元格值等
- private void buttonTest_Click(object sender, EventArgs e)
- {
- string excelFilePath = string.Format("{0}Excel-20100314181502.xls", AppDomain.CurrentDomain.BaseDirectory);
- using (ExcelHandler handler = new ExcelHandler(excelFilePath, false))//设置第二个参数为false表示直接打开现有的Excel文档
- {
- handler.OpenOrCreate();
- //获得Worksheet对象
- Worksheet sheet = handler.GetWorksheet("TestSheet");
- //A1-E5
- Range range = handler.GetRange(sheet, 1, 1, 5, 5);
- handler.SetRangeFormat(range);
- handler.SetCellValue(sheet, 1, 1, "测试");
- handler.SetCellValue(sheet, 2, 1, "测试2");
- range.Font.Bold = true;//加粗
- handler.Save();
- }
- }
效果如下:
2.4导入DataTable
代码如下:
- private void buttonTest_Click(object sender, EventArgs e)
- {
- string excelFilePath = string.Format("{0}Excel-20100314181502.xls", AppDomain.CurrentDomain.BaseDirectory);
- using (ExcelHandler handler = new ExcelHandler(excelFilePath, false))//设置第二个参数为false表示直接打开现有的Excel文档
- {
- handler.OpenOrCreate();
- //获得Worksheet对象
- Worksheet sheet = handler.GetWorksheet("TestSheet");
- //A1-E5
- Range range = handler.GetRange(sheet, 1, 1, 5, 5);
- handler.SetRangeFormat(range);
- range.Font.Bold = true;
- System.Data.DataTable table = new System.Data.DataTable();
- table.Columns.AddRange(new DataColumn { new DataColumn("测试列1"), new DataColumn("测试列2"), new DataColumn("测试列3") });
- Random random = new Random(20);
- for (int i = 0; i < 10; i++)
- {
- table.Rows.Add(random.Next(10000), random.Next(10000), random.Next(10000));
- }
- //从第6行第一列导入数据
- handler.ImportDataTable(sheet, "测试导入表格", true, new string { "测试列1", "测试列2", "测试列3" }, 6, 1, table);
- handler.Save();
- }
- }
结果如下图:
2.5 插入图片
下面插入一张图片到Excel的第一行第五列,代码如下:
- private void buttonTest_Click(object sender, EventArgs e)
- {
- string excelFilePath = string.Format("{0}Excel-20100314181502.xls", AppDomain.CurrentDomain.BaseDirectory);
- using (ExcelHandler handler = new ExcelHandler(excelFilePath, false))//设置第二个参数为false表示直接打开现有的Excel文档
- {
- handler.OpenOrCreate();
- //获得Worksheet对象
- Worksheet sheet = handler.GetWorksheet("TestSheet");
- //图片地址
- string filePath = string.Format("{0}test.png", AppDomain.CurrentDomain.BaseDirectory);
- //从第1行第5列插入图片
- Picture pic = handler.AddImage(sheet, filePath, 1, 5);
- handler.Save();
- }
- }
效果如下图:
