c#将Excel数据传入Oracle数据库的方法和Oracle的传参规范

1.如果传递的是到Oracle中是date类型的string.Format()方式的问题实例：

   string strinsert=string.Format("insert into tabextotab(ID,name,thetime) values({0},'{1}',to_date('{2}','yyyy-mm-dd hh24:mi:ss') )",id,name,ptime);

2.使用规范传参方式实现Excel指入oracle

         public void GetInsertToOracle(string Path)
         {
             DataSet ds;
             if (File.Exists(Path))
                 ds = ImportExcel(Path);   //获得Excel
             else
                 return;

             int odr = 0;

             OracleConnection conn = new OracleConnection("Data Source=orcl;User ID=scott;Password=leiyinghua");//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);
             }
         }
