我之前也捣鼓了好长时间,已经再用了,可行- DataSet ds = new DataSet();
- try
- {
- //获取全部数据
- string strConn = "Provider=Microsoft.Jet.OLEDB.4.0;" + "Data Source=" + excelFile + ";" + "Extended Properties=Excel 8.0;";
- OleDbConnection conn = new OleDbConnection(strConn);
- conn.Open();
- string strExcel = "";
- OleDbDataAdapter myCommand = null;
- strExcel = string.Format("select * from [{0}$]", sheetName);
- myCommand = new OleDbDataAdapter(strExcel, strConn);
- myCommand.Fill(ds, sheetName);
- //如果目标表不存在则创建
- string strSql = string.Format("if object_id('{0}') is null create table {0}(", sheetName);
- foreach (System.Data.DataColumn c in ds.Tables[0].Columns)
- {
- strSql += string.Format("[{0}] varchar(255),", c.ColumnName);
- }
- strSql = strSql.Trim(',') + ")";
- using (System.Data.SqlClient.SqlConnection sqlconn = new System.Data.SqlClient.SqlConnection(connectionString))
- {
- SqlCommand cmd = sqlconn.CreateCommand();
- cmd.CommandText = "drop table Sheet1";
- sqlconn.Open();
- cmd.ExecuteNonQuery();
- System.Data.SqlClient.SqlCommand command = sqlconn.CreateCommand();
- command.CommandText = strSql;
- command.ExecuteNonQuery();
- sqlconn.Close();
- }
- //用bcp导入数据
- using (System.Data.SqlClient.SqlBulkCopy bcp = new System.Data.SqlClient.SqlBulkCopy(connectionString))
- {
- bcp.SqlRowsCopied += new System.Data.SqlClient.SqlRowsCopiedEventHandler(bcp_SqlRowsCopied);
- bcp.BatchSize = 100;//每次传输的行数
- bcp.NotifyAfter = 100;//进度提示的行数
- bcp.DestinationTableName = sheetName;//目标表
- bcp.WriteToServer(ds.Tables[0]);
- }
- MessageBox.Show("数据导入成功");
- }
- catch (Exception ex)
- {
- System.Windows.Forms.MessageBox.Show(ex.Message);
- }
