aspose.cells html excel导出,C#使用Aspose.Cells导出Excel简单实现
首先，需要添加引用Aspose.Cells.dll，官网下载地址：http://downloads.aspose.com/cells/net
将DataTable导出Xlsx格式的文件下载(网页输出)：
1 ///
2 /// 导出Excel表格
3 ///
4 /// 数据集合
5 /// 数据表头
6 ///
7 public void ExportExcel(DataTable dt, string[] header)
8 {
9 Workbook wb = new Workbook(FileFormatType.Xlsx);
10 try
11 {
12 Worksheet sheet = wb.Worksheets[0];
13 sheet.Name = "MO上行查询结果";
14 if (dt.Rows.Count <= 0)
15 {
16 System.Web.HttpContext.Current.Response.Write("");
17 return;
18 }
19 // 为单元格添加样式
20 Aspose.Cells.Style style = wb.CreateStyle();
21 style.HorizontalAlignment = Aspose.Cells.TextAlignmentType.Center; //设置居中
22 style.Font.Size = 12;//文字大小
23 style.Font.IsBold = true;//粗体
24 style.HorizontalAlignment = TextAlignmentType.Center;//文字居中
25
26 int rowIndex = 0;
27 for (int i = 0; i < header.Length; i++)
28 {
29 sheet.Cells[rowIndex, i].PutValue(header[i]);
30 sheet.Cells[rowIndex, i].SetStyle(style);
31 sheet.Cells.SetColumnWidth(i, 20);//设置宽度
32 }
33 for (int i = 0; i < dt.Rows.Count; i++)//遍历DataTable行
34 {
35 sheet.Cells[i + 1, 0].PutValue(dt.Rows[i]["SENDER"].ToString());
36 sheet.Cells[i + 1, 1].PutValue(dt.Rows[i]["SENDCONTENT"].ToString());
37 sheet.Cells[i + 1, 2].PutValue("");
38 sheet.Cells[i + 1, 3].PutValue(dt.Rows[i]["RECDATE"].ToString());
39 sheet.Cells[i + 1, 4].PutValue(dt.Rows[i]["sn"].ToString());
40 }
41 }
42 catch (Exception e)
43 {
44 System.Web.HttpContext.Current.Response.Write("");
45 }
46 #region 输出到Excel
47 using (MemoryStream ms = new MemoryStream())
48 {
49
50 wb.Save(ms, new OoxmlSaveOptions(SaveFormat.Xlsx));//默认支持xls版，需要修改指定版本
51 System.Web.HttpContext.Current.Response.AddHeader("Content-Disposition", string.Format("attachment; filename={0}.xlsx", DateTime.Now.ToString("yyyyMMddHHmmssfff")));
52 System.Web.HttpContext.Current.Response.ContentType = "application/vnd.ms-excel";
53 System.Web.HttpContext.Current.Response.BinaryWrite(ms.ToArray());
54 wb = null;
55 System.Web.HttpContext.Current.Response.End();
56 }
57 #endregion
58 }

Aspose.Cells组件可以不依赖excel来导入导出excel文件：
导入：
public static System.Data.DataTable ReadExcel(String strFileName)
{
Workbook book = new Workbook();
book.Open(strFileName);
Worksheet sheet = book.Worksheets[0];
Cells cells = sheet.Cells;
return cells.ExportDataTableAsString(0, 0, cells.MaxDataRow + 1, cells.MaxDataColumn + 1, true);
}
导出：
private static void Export(IEnumerable data, HttpResponse response)
{
Workbook workbook = new Workbook();
Worksheet sheet = (Worksheet)workbook.Worksheets[0];
PropertyInfo[] ps = typeof(T).GetProperties();
var colIndex = "A";
foreach (var p in ps)
{
sheet.Cells[colIndex + 1].PutValue(p.Name);
int i = 2;
foreach (var d in data)
{
sheet.Cells[colIndex + i].PutValue(p.GetValue(d, null));
i++;
}
colIndex = ((char)(colIndex[0] + 1)).ToString();
}
response.Clear();
response.Buffer = true;
response.Charset = "utf-8";
response.AppendHeader("Content-Disposition", "attachment;filename=xxx.xls");
response.ContentEncoding = System.Text.Encoding.UTF8;
response.ContentType = "application/ms-excel";
response.BinaryWrite(workbook.SaveToStream().ToArray());
response.End();
}
非常简单，好用！
