前幾天，一直在網(wǎng)上搜索資料，想實現(xiàn)這個功能，都沒找到我想要的結(jié)果，最后只要自己想辦法實現(xiàn)了害怕忘記，把它貼出來，以便以后使用，也給需要這個功能的人提供點思路：大體思路是：將EXCEL的數(shù)據(jù)提出放在數(shù)據(jù)集中，在過循環(huán)將主表數(shù)據(jù)插入，在通過循環(huán)將從表插入：代碼如下：

private void button1_Click(object sender, System.EventArgs e){//選擇文件 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());} }}

********************************************************提取數(shù)據(jù)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 {
