前几天，一直在网上搜索资料，想实现这个功能，都没找到我想要的结果，最后只要自己想办法实现了害怕忘记，把它贴出来，以便以后使用，也给需要这个功能的人提供点思路：大体思路是：将EXCEL的数据提出放在数据集中，在过循环将主表数据插入，在通过循环将从表插入：代码如下：
private void button1_Click(object sender, System.EventArgs e){//选择文件 ofdSelectExcel.Filter = "Excel Files(*.xls)|*.xls"; ofdSelectExcel.RestoreDirectory = true; if( ofdSelectExcel.ShowDialog() == DialogResult.OK ) { if ( ofdSelectExcel.FileName.Trim().Length == 0) { MessageBox.Show(this,"Please select a excel file first!"); return; } else { ImportExcelToSqlServer(ofdSelectExcel.FileName.Trim()); } }}
********************************************************提取数据public void ImportExcelToSqlServer(string fileName){ if (fileName == null) { throw new ArgumentNullException("filename string is null!"); }
if (fileName.Length == 0) { throw new ArgumentException("filename string is empty!"); }
string oleDBConnString = String.Empty; oleDBConnString = "Provider=Microsoft.Jet.OLEDB.4.0;"; oleDBConnString += "Data Source="; oleDBConnString += fileName; oleDBConnString += ";Extended Properties=Excel 8.0;";
OleDbConnection oleDBConn = null; OleDbDataAdapter oleAdMaster = null; DataTable m_tableName=new DataTable();; DataSet ds=new DataSet(); try { oleDBConn = new OleDbConnection(oleDBConnString); oleDBConn.Open(); m_tableName=oleDBConn.GetOleDbSchemaTable(OleDbSchemaGuid.Tables,null); if (m_tableName != null && m_tableName.Rows.Count > 0) {
m_tableName.TableName =m_tableName.Rows[0]["TABLE_NAME"].ToString();
} string sqlMaster; sqlMaster=" SELECT * FROM ["+m_tableName+"]"; oleAdMaster=new OleDbDataAdapter(sqlMaster,oleDBConn); oleAdMaster.Fill(ds,"m_tableName"); MailRebateManager manger=new MailRebateManager(); bool isSucess=manger.AddExceLGmailRebate(ds.Tables["m_tableName"],ApplicationVariable.HomeCompanyID); if(isSucess) { MessageBox.Show("Manipulate Succs!"); } else { MessageBox.Show("Manipulate Failed"); } } catch(Exception ex) { MessageBox.Show(ex.Message); SimpleLogger.Log(ex); try {
} catch (OleDbException e) { SimpleLogger.Log(e); MessageBox.Show("An exception of type " + e.GetType() +"); } }
}*****************************************将数据进行处理分别插入主表和从表public bool AddExceLGmailRebate(DataTable tb,string homeCompanyID){bool ret=false;SqlConnection con=null; DataTable table=new DataTable();table=tb; string sConn = PublicManager.GetDBConnectionString(homeCompanyID);con=new SqlConnection();con.ConnectionString=sConn; SqlTransaction tran=null;SqlCommand com=null;SqlCommand comm=null; try{con.Open();tran = con.BeginTransaction(); if (table != null && table.Rows.Count > 0) { for(int i=1;i { string m_PromoCode=Convert.ToString(table.Rows[i][0]); if(m_PromoCode=="") { m_PromoCode=Convert.ToString(table.Rows[i-1][0]); } if(m_PromoCode.Length>50 ) { m_PromoCode=m_PromoCode.Substring(0,50); }
