本文提供了一个使用C#和VB.NET从Excel文件中读取数据的示例代码。通过ADO数据集命令从Excel的第一张工作表中选择所有记录，并将数据填充到数据集中，最后展示在DataGrid中。

C# Code
---------------------------------------------
<%@ Page Language="C#" %>
<%@ Import Namespace="System.Data" %>
<%@ Import Namespace="System.Data.ADO" %>
<script language="C#" runat="server">
protected void Page_Load(Object Src, EventArgs E)
{
string strConn;
strConn = "Provider=Microsoft.Jet.OLEDB.4.0;"
+"Data Source=C://exceltest.xls;"
+"Extended Properties=Excel 8.0;";
ADODataSetCommand myCommand = new ADODataSetCommand("SELECT * FROM [Sheet1$]", strConn);
DataSet myDataSet = new DataSet();
myCommand.FillDataSet(myDataSet, "ExcelInfo");
DataGrid1.DataSource = myDataSet.Tables["ExcelInfo"].DefaultView;
DataGrid1.DataBind();
}
</script>
<p><asp:Label id=Label1 runat="server">Excel表格内容:</asp:Label></p>
<asp:DataGrid id=DataGrid1 runat="server"/>

VB.NET Code
----------------------------------------------
<%@ Page Language="VB" %>
<%@ Import Namespace="System.Data" %>
<%@ Import Namespace="System.Data.ADO" %>
<script language="VB" runat="server">
Sub Page_Load(sender As Object, e As EventArgs)
Dim myDataset As New DataSet()
Dim strConn As String = "Provider=Microsoft.Jet.OLEDB.4.0;" _
& "Data Source=C:/exceltest.xls;" _
& "Extended Properties=""Excel 8.0;"""
Dim myADODataSetCommand As New ADODataSetCommand("SELECT * FROM [Sheet1$]", strConn)
myADODataSetCommand.TableMappings.Add("Table", "ExcelTest")
myADODataSetCommand.FillDataSet(myDataset)
DataGrid1.DataSource = myDataset.Tables(0).DefaultView
DataGrid1.DataBind()
End Sub
</script>
<p><asp:Label id=Label1 runat="server">Excel表格内容:</asp:Label></p>
<asp:DataGrid id=DataGrid1 runat="server"/>
