从Excel读取到ASP.NET中的GridView

我想从Excel文件xlsx读取数据，并将数据绑定到GridView。 但是当我尝试这种方式时，我得到以下exception

Microsoft Access数据库引擎无法打开或写入文件“”。 它已经由另一个用户专门打开，或者您需要查看和写入其数据的权限。

任何想法如何解决它？

代码隐藏：

 public partial class Default : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { string connString = ConfigurationManager.ConnectionStrings["xlsx"].ConnectionString; // Create the connection object OleDbConnection oledbConn = new OleDbConnection(connString); try { // Open connection oledbConn.Open(); // Create OleDbCommand object and select data from worksheet Sheet1 OleDbCommand cmd = new OleDbCommand("SELECT * FROM [Sheet1$]", oledbConn); // Create new OleDbDataAdapter OleDbDataAdapter oleda = new OleDbDataAdapter(); oleda.SelectCommand = cmd; // Create a DataSet which will hold the data extracted from the worksheet. DataSet ds = new DataSet(); // Fill the DataSet from the data extracted from the worksheet. oleda.Fill(ds, "Employees"); // Bind the data to the GridView this.gvExcel.DataSource = ds.Tables[0].DefaultView; this.gvExcel.DataBind(); } catch(Exception exc) { } finally { // Close connection oledbConn.Close(); } } } 

aspx代码：

  <asp:GridView ID="gvExcel" runat="server" AutoGenerateColumns="false"> <Columns> <asp:BoundField DataField="Name" HeaderText="Name" SortExpression="Name" /> </Columns> </asp:GridView>
