Hi, I am trying to copy som data from an excel document that I have on the server into a table in my ms sql server.
I think the problem now is that I am having trouble connecting to the sql server.

I'm using sql server 2005.

You can see the error message here:
and then click on the button.

This is all the code I have written:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Data.SqlClient;
using System.Data;
using System.Configuration;
using System.Collections;
using System.Web.Security;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;
using System.Data.Common;
using System.Data.OleDb;

public partial class _Default : System.Web.UI.Page
    protected void Page_Load(object sender, EventArgs e)


    protected void Button1_Click(object sender, EventArgs e)
        string excelConnectionString = string.Format(@"Provider=Microsoft.Jet.OLEDB.4.0;Data Source={0};Extended Properties=""Excel 8.0;HDR=YES;""", Server.MapPath("database.xls"));

        using (OleDbConnection connection =
             new OleDbConnection(excelConnectionString))

            OleDbCommand command = new OleDbCommand
            ("Select ID,Data FROM [Sheet1$]", connection);


            using (DbDataReader dr = command.ExecuteReader())
                string sqlConnectionString = "Data Source=;Initial Catalog=Test;Integrated Security=True";

                using (SqlBulkCopy bulkCopy =
                   new SqlBulkCopy(sqlConnectionString))
                    bulkCopy.DestinationTableName = "ExcelData";


I hope someone can help me with the problem?
