您可以轻松搜索互联网并找到无数的例子，所以我认为它现在必须被打破。幸运的是，我碰巧有一个链接可以帮助它恢复运行。

You could have easily searched the internet and found countless examples of this, so I presume it must be broken right now. Fortunately I just happen to have a link that will help if it gets back up and running.

您可以使用以下方法将xls数据插入数据库。

You can use the below approach for inserting xls data into database.

if (openFileDialog.ShowDialog(this) == DialogResult.OK)
                    {
                        path = openFileDialog.InitialDirectory + openFileDialog.FileName;
                    }
                    string constring = "Provider=Microsoft.ACE.OLEDB.12.0; Data Source=" + path + "; Extended Properties=Excel 12.0 Xml";
                    OleDbConnection con = new OleDbConnection(constring);
                    try
                    {
                        con.Open();
                        dt = con.GetOleDbSchemaTable(OleDbSchemaGuid.Tables, null);
                        String[] excelSheets = new String[dt.Rows.Count];
                        i = 0;
                        foreach (DataRow row in dt.Rows)
                        {
                            excelSheets[i] = row["TABLE_NAME"].ToString();
                            i++;
                        }
 
                        for (int j = 0; j < excelSheets.Length; j++)
                        {
                            string query = "SELECT * FROM [" +excelSheets[j]+ "]; ";
                            OleDbDataAdapter adp = new OleDbDataAdapter(query, constring);
 
                            DataSet ds = new DataSet();
                            string hCode = string.Empty;
                            string description = string.Empty;
                            adp.Fill(ds);
 
                            foreach (DataRow dr in ds.Tables[0].Rows)
                            {
                                hCode = Convert.ToString(dr[1]);
                                description = Convert.ToString(dr[2]);
                                if (!(string.IsNullOrEmpty(hCode) && string.IsNullOrEmpty(description)))
                                {
 
                                    dboject.InsertSiteNameIntoDatabase(hCode, description);
 
                                }
                            }
 

                        }
                        lblDisplay.Text = "Inserted successfully";
                    
                    }
                    catch (Exception ex)
                    {
                        dboject.VMSLog(ex.Message);
 
                    }
                    finally
                    {
                        con.Close();
 
                    }
