如何从网站上传Excel文件并以编程方式将数据导入SQL Server？
我正在尝试做这样的事情：
public void ImportClick(object sender, EventArgs e) //the button used after selecting the spreadsheet file { if (fileUpload.HasFile) //ASP.Net FileUpload control { if (fileUpload.FileName.EndsWith(".xls", StringComparison.OrdinalIgnoreCase) || fileUpload.FileName.EndsWith(".xlsx", StringComparison.OrdinalIgnoreCase)) { Excel sheet = new Excel(fileUpload.Open()); //not sure how to do this part using (SqlConnection connection = new SqlConnection(ConfigurationManager.ConnectionStrings["our_database"].ConnectionString)) { using (SqlCommand command = new SqlCommand("INSERT INTO table_name SELECT * FROM " + sheet, connection)) { connection.Open(); command.ExecuteQuery(); //Intellisense only has "ExecuteNonQuery()" method, but that's for T-SQL connection.Close(); } } } else { error.Text = "File must be either *.xls or *.xlsx"; error.Visible = true; } } else { error.Text = "No file was selected"; error.Visible = true; } } Microsoft.Office.Interop.Excel命名空间中有很多类和接口，我不知道使用哪一个。
我知道制作Excel对象以及SQL命令可能不会像我在这里那么容易，但这些是我需要帮助的两件事。
任何建议/意见将不胜感激！
我建议使用Microsoft Jet Engine。
private static void UploadExcelToDB(string p) { try { using (SqlConnection conn = new SqlConnection(DBConnString)) { conn.Open(); if (conn.State == ConnectionState.Open) { Log("Opened connection to DB"); } SqlBulkCopy sbk = new SqlBulkCopy(conn); sbk.BulkCopyTimeout = 600; sbk.DestinationTableName = DbTableName; DataTable excelDT = new DataTable(); OleDbConnection excelConn = new OleDbConnection(ExcelConnString.Replace("xFILEx",p)); excelConn.Open(); if (excelConn.State == ConnectionState.Open) { Log("Opened connection to Excel"); } OleDbCommand cmdExcel = new OleDbCommand(); OleDbDataAdapter oda = new OleDbDataAdapter(); cmdExcel.CommandText = "SELECT * FROM ["+ExcelTableName+"]"; cmdExcel.Connection = excelConn; oda.SelectCommand = cmdExcel; oda.Fill(excelDT); if (excelDT != null) { Log("Fetched records to local Data Table"); } excelConn.Close(); SqlCommand sqlCmd = new SqlCommand("TRUNCATE TABLE ICN_NUGGET_REPORT_RAW",conn); sqlCmd.CommandType = CommandType.Text; Log("Trying to clear current data in table"); int i = sqlCmd.ExecuteNonQuery(); Log("Table flushed"); Log("Trying write new data to server"); sbk.WriteToServer(excelDT); Log("Written to server"); conn.Close(); } } catch (Exception ex) { Log("ERROR: " + ex.Message); SendErrorReportMail(); } finally { #if (DEBUG) { } #else { string archive_file = ArchiveDir+"\\" + DateTime.Now.ToString("yyyyMMdd-Hmmss") + ".xlsx"; File.Move(p, archive_file); Log("Moved processed file to archive dir"); Log("Starting archive process..."); } #endif } }
这就是ExcelConnString样子：
public static string ExcelConnString { get { return "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=xFILEx;Extended Properties=\"Excel 12.0;HDR=YES\";";} }
HDR = YES – 这意味着如果您在电子表格中有列名称，它将被视为目标表列名称，以便相互匹配。
我正在考虑创建一个excel.application类的实例，并编写代码来遍历单元格。 并使用SQL插入查询将行逐个复制到SQL表。 无论如何我仍在努力，并在完成后粘贴代码。
