把Excel文件中的数据读入到Gridview中

1、引用using System.Data.OleDb;

2、
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{

//获得数据集，将数据进行绑定。
GridView1.DataSource = CreateDataSource();
GridView1.DataBind();
}
}
private DataSet CreateDataSource()
{
string strConn;
strConn = "Provider=Microsoft.Jet.OLEDB.4.0;" + "Data Source=F://aaa.xls;" + "Extended Properties=Excel 8.0;";
OleDbConnection conn = new OleDbConnection(strConn);

OleDbDataAdapter myCommand = new OleDbDataAdapter("SELECT * FROM [Sheet1$]", strConn);

DataSet myDataSet = new DataSet();
myCommand.Fill(myDataSet);
return myDataSet;

}
//选定路径；在[]内选定工作薄。

3、前台页面：

<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False">
<Columns>
<asp:BoundField DataField="userid" HeaderText="id" />
<asp:BoundField DataField="username" HeaderText="name" />
</Columns>
</asp:GridView>

4、Excel中的文件类似于：

userid username

1 aaa

2 bbb

3 ccc
