Excel Reader ASP.NET

Question

我在ASP.NET视图中声明了一个DataGrid，我想生成一些C＃代码，用Excel电子表格（.xlsx）填充所述DataGrid。这是我的代码：

<asp:DataGrid id="DataGrid1" runat="server"/>
        <script language="C#" runat="server">
            protected void Page_Load(object sender, EventArgs e)
            {
                string connString = @"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=c:\FileName.xlsx;Extended Properties=""Excel 12.0;HDR=YES;""";
                // 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 [sheetname$]", 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, "Something");

                    // Bind the data to the GridView
                    DataGrid1.DataSource = ds.Tables[0].DefaultView;
                    DataGrid1.DataBind();
                }
                catch
                {
                }
                finally
                {
                    // Close connection
                    oledbConn.Close();
                }
            }
        </script>

当我运行网站时，没有任何事情发生。是什么给了什么？

旧的JET驱动程序不但支持XLSX格式，只支持BIFF（XLS）格式。

你的连接字符串需要这样的东西：

 Provider=Microsoft.ACE.OLEDB.12.0;Data Source=c:\FileName.xlsx;Extended Properties="Excel 12.0;HDR=Yes;IMEX=2"

您还需要在网络服务器上下载并安装它：
