在asp.net中导出表格Excel数据

第一步:需要引用org.in2bits.MyXls程序集到使用页面

第二步:前台代码

<asp:Button ID="LeadingOut" runat="server" Text="导出"  onclick="LeadingOut_Click" />

第三步:在aspx文件的后台写按钮的点击事件

protected void LeadingOut_Click(object sender, EventArgs e)
{

DataSet ds = consumableBll.GetList(" IsDel=‘false‘");//要导出的表数据

if (null == ds.Tables[0])
return;

//生成Excel
ExcelFile excel = new ExcelFile();//ExcelFile 是公共类要解析
//设置列属性
excel.SetColumnInfo(true, 90 * 60, 0, 15);
excel.SetColumnInfo(true, 90 * 60, 4, 4);
excel.SetColumnInfo(true, 90 * 60, 8, 8);

//设置单元格格式
XF cellXF = excel.SetXF(true, false, HorizontalAlignments.Centered, VerticalAlignments.Centered);
XF cellXF1 = excel.SetXF(false, true, HorizontalAlignments.Centered, VerticalAlignments.Centered);
cellXF1.Pattern = 1;
cellXF1.PatternBackgroundColor = Colors.Red;

//红色Default0A；绿Default0B,浅绿Default0F,灰色Default16，紫色Default18,墨绿：Default26，淡蓝色：Default28，浅蓝Default29
cellXF1.PatternColor = Colors.Default28;
//设置表头信息
List<string> headInfo = new List<string>();

headInfo.Add("名称");//要导出的字段
headInfo.Add("数量");
headInfo.Add("有效期");

excel.SetHeader(1, 1, cellXF1, headInfo);
int icount = 1;
int hcount = 1;
foreach (DataRow row in ds.Tables[0].Rows)
{
excel.SetDataValue(++icount, ref hcount, cellXF,

row["Name"].ToString(),//要导出的数据字段对应
row["Number"].ToString(),
row["AddTime"].ToString()

);
hcount = 1;
}
string fileName = DateTime.Now.ToString("yyyyMMddhhmmss");
Response.Clear();
Response.ClearHeaders();
Response.Buffer = true;
Response.Charset = "UTF-8";
Response.ContentEncoding = System.Text.Encoding.GetEncoding("GB2312");
Response.ContentType = "application/octet-stream";
Response.AppendHeader("Content-Disposition",
"attachment;filename=" + fileName + ".xls");
Response.BinaryWrite(excel.Download());
HttpContext.Current.Response.End();
}

第四步：生成公共类ExcelFile

using System.Reflection;
using org.in2bits.MyXls;

_sheet.AddColumnInfo(cInfo);
