把Excel文件中的数据读入到DataGrid中

使用Excel文件做为DataGrid的数据源是非常简单的，一旦数据被装载进来，就可以把数据再保存进SQL Server或XML中。我们只需要简单地使用OLE DB Provider 来访问Excel文件，然后返回DataSet即可。

<%@ Page Language="C#" Debug="true" %>
<%@ Import Namespace="System.Data"%>
<%@ Import Namespace="System.Data.OleDb"%>

<script runat="server">

private DataSet CreateDataSource(){
string strConn;
strConn = "Provider=Microsoft.Jet.OLEDB.4.0;" +
"Data Source=C:\\Inetpub\\wwwroot\\contacts.xls;"+
"Extended Properties=Excel 8.0;";
OleDbConnection conn = new OleDbConnection(strConn);
OleDbDataAdapter myCommand = new OleDbDataAdapter("SELECT * FROM [ContactList$]", strConn);
DataSet myDataSet = new DataSet();
myCommand.Fill(myDataSet);
return myDataSet;
}


public void Page_Load(Object sender, EventArgs e){
if (!IsPostBack) {
mygrid.DataSource = CreateDataSource();
mygrid.DataBind();
}

}


</script>
