<%@ Import Namespace="System.Data" %>
<%@ Import Namespace="System.Data.SqlClient" %>

<script language="c#" runat="server">
//定义方法GetData(),返回一个数据表
private System.Data.DataTable GetData()
{

SqlConnection conn= new SqlConnection("server=(local);database=Northwind;uid=sa;pwd=jiao");
SqlDataAdapter adapter= new SqlDataAdapter(("select*from Table1"),conn);
DataSet ds=new DataSet();

try

{
adapter.Fill(ds,"UserId");
}
catch(Exception ex)
{
MessageBox.Show(ex.ToString());（MessageBox说我没有定义？？？）
}
return ds.Tables[0];

}

//按钮
private void button1_Click(object sender, System.EventArgs e)
{

Excel.Application excel= new Excel.Application();
int rowIndex=1;
int colIndex=0;

excel.Application.Workbooks.Add(true);

DataTable table=GetData();

//将所得到的表的列名,赋值给单元格
foreach(DataColumn col in table.Columns)
{
colIndex++;
excel.Cells[1,colIndex]=col.ColumnName;
}

//同样方法处理数据
foreach(DataRow row in table.Rows)
{
rowIndex++;
colIndex=0;

foreach(DataColumn col in table.Columns)
{
colIndex++;
excel.Cells[rowIndex,colIndex]=row[col.ColumnName].ToString();
}
}
//不可见,即后台处理
excel.Visible=true;
}
</script>
