c# winform 把Excel里的数据导入到Oracle数据库里，读取excel到dataset

winform程序，点击程序上的按钮，找到Excel文件，打开后把这个Excel里的数据导入到oracle数据库里

#region 导入Excel数据到数据库

private void button3_Click(object sender, EventArgs e)
{
	DataSet ds;
	if (openFileDialog1.ShowDialog() == DialogResult.OK)
	{
		ds = ImportExcel(this.openFileDialog1.FileName);//获得Excel
	}
	else
	{
		return;
	}

	int odr = 0;

	OracleConnection conn = dbc.getConnection();//获得conn连接

	try
	{
		conn.Open();

		OracleCommand cmd = conn.CreateCommand();

		cmd.CommandText = "INSERT INTO kk.kkhmd (xh,hpzl,hphm,bz,larq,fdjh,clpp,cjh,jdcsyr,cllx,csys) VALUES(:xh,:hpzl,:hphm,:bz,:larq,:fdjh,:clpp,:cjh,:jdcsyr,:cllx,:csys) ";//删除记录

		int dsLength = ds.Tables[0].Rows.Count;//获得Excel中数据长度

		for (int i = 1; i < dsLength; i++)
		{
			cmd.Parameters.Add("xh", OracleType.VarChar).Value = ds.Tables[0].Rows[i][0];
			cmd.Parameters.Add("hpzl", OracleType.VarChar).Value = ds.Tables[0].Rows[i][1];
			cmd.Parameters.Add("hphm", OracleType.VarChar).Value = ds.Tables[0].Rows[i][2];
			cmd.Parameters.Add("bz", OracleType.VarChar).Value = ds.Tables[0].Rows[i][3];
			cmd.Parameters.Add("larq", OracleType.DateTime).Value = ds.Tables[0].Rows[i][4];
			cmd.Parameters.Add("fdjh", OracleType.VarChar).Value = ds.Tables[0].Rows[i][5];

			cmd.Parameters.Add("clpp", OracleType.VarChar).Value = ds.Tables[0].Rows[i][6];
			cmd.Parameters.Add("cjh", OracleType.VarChar).Value = ds.Tables[0].Rows[i][7];
			cmd.Parameters.Add("jdcsyr", OracleType.VarChar).Value = ds.Tables[0].Rows[i][8];

			cmd.Parameters.Add("cllx", OracleType.VarChar).Value = ds.Tables[0].Rows[i][9];
			cmd.Parameters.Add("csys", OracleType.VarChar).Value = ds.Tables[0].Rows[i][10];

			odr = cmd.ExecuteNonQuery();//提交
		}

		//如果查到了数据，才使控制分页按钮生效
		if (odr > 0 )
		{
			MessageBox.Show("导入成功");
		}
		conn.Close();
	}
	catch (Exception ee)
	{
		MessageBox.Show(ee.Message.ToString(), "错误", MessageBoxButtons.OK, MessageBoxIcon.Error);
	}

}

		
public static DataSet ImportExcel(string file)
{
	FileInfo fileInfo = new FileInfo(file);
	if (!fileInfo.Exists)
		return null;

	string strConn = @"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + file + ";Extended Properties='Excel 8.0;HDR=NO;IMEX=1'";
	OleDbConnection objConn = new OleDbConnection(strConn);
	DataSet dsExcel = new DataSet();
	try
	{
		objConn.Open();
		string strSql = "select * from  [Sheet1$]";
		OleDbDataAdapter odbcExcelDataAdapter = new OleDbDataAdapter(strSql, objConn);
		odbcExcelDataAdapter.Fill(dsExcel);
		return dsExcel;
	}
	catch (Exception ex)

还有一个是读到DataTable里

用oledb方式读取excel到datatable，然后再写入数据库。

private DataTable GetData(string strPath) 
{ 
    DataTable dtbl = new DataTable(); 
    try 
    { 
        string strCon = "Provider=Microsoft.Jet.OLEDB.4.0;" + "Data Source=" + strPath + ";" + "Extended Properties=Excel 8.0;"; 
        string strSheetName = ""; 
        using (OleDbConnection con = new OleDbConnection(strCon)) 
        { 
            con.Open(); 
            DataTable dtbl1 = con.GetOleDbSchemaTable(OleDbSchemaGuid.Tables, null); 
            //dataGridView2.DataSource = dtbl1; 
            strSheetName = dtbl1.Rows[0][2].ToString().Trim(); 
        } 
        String strCmd = "select * from [" + strSheetName + "]"; 
        OleDbDataAdapter cmd = new OleDbDataAdapter(strCmd, strCon); 
        cmd.Fill(dtbl); 
    } 
    catch (Exception ex) { MessageBox.Show(ex.Message); } 
    return dtbl; 
}
