Excel을 DataSet으로 변환하여 데이터베이스에 저장

Excel을 DataSet으로 전환
1. 먼저 Excel 파일을 업로드하여 업로드된 Excel 파일의 절대 경로를 찾습니다.
2. Excel의 데이터를 DataSet에 읽기;

        /// <summary>
        ///  Excel DataSet
        /// </summary>
        /// <param name="path">Excel </param>
        /// <returns> </returns>
        public static DataSet ExcelToDataSet(string path)
        {
            string strConn = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + path + ";Extended Properties=Excel 8.0;";
            DataSet myDataSet = new DataSet();
            using (OleDbConnection myOleDbConnection = new OleDbConnection(strConn))
            {
                myOleDbConnection.Open();
                string strExcel = " select * from [sheet1$]";
                using (OleDbCommand myOleDbCommand = new OleDbCommand(strExcel, myOleDbConnection))
                {
                    myOleDbCommand.ExecuteNonQuery();
                    using (OleDbDataAdapter myOleDbDataAdapter = new OleDbDataAdapter(myOleDbCommand))
                    {
                        myOleDbDataAdapter.Fill(myDataSet);
                    }
                }
            }
            return myDataSet;
        }

3. SqlCommandBuilder와 결합하여 DataSet의 데이터를 데이터베이스에 저장한다.

        /// <summary>
        ///  DataSet 
        /// </summary>
        /// <param name="sql"> </param>
        /// <param name="strTblName"> </param>
        /// <returns></returns>
	public static int CommondDataTable(DataTable dt, string strTblName)
        {
 
            using (SqlConnection Connection = new SqlConnection(connectionString))
            {
                Connection.Open();
                SqlTransaction trans = Connection.BeginTransaction();
                try
                {
                    SqlDataAdapter adapter = new SqlDataAdapter();
                    SqlCommand cmd = new SqlCommand("select * from " + strTblName, Connection);
                    cmd.Transaction = trans;
                    adapter.SelectCommand = cmd;
                    SqlCommandBuilder cmdBuilder = new SqlCommandBuilder(adapter);
                    int reuslt = adapter.Update(dt);
                    trans.Commit();
                    return reuslt;
                }
                catch (Exception ex)
                {
                    trans.Rollback();
                    return 0;
                }
            }
        }
