INSERT TO上的订单

我正在使用OLEDB来插入现有的Excel工作表。但我想以某种顺序插入。所以我有这个:

    File.Copy(lTemplateFolder + lFilename, lDistributorFolder + lFilename, true);
    string lConnectionString = @"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + lDistributorFolder + "\\" + lFilename + ";Extended Properties=\"Excel 8.0;HDR=YES;\"";
    DbProviderFactory lFactory = DbProviderFactories.GetFactory("System.Data.OleDb");
    int lSequence = 0;

    using (DbConnection lConnection = lFactory.CreateConnection())
    {
        lConnection.ConnectionString = lConnectionString;
        lConnection.Open();

        foreach (DataRowView rowView in dv)
        {
            DataRow row = rowView.Row;

            lSequence++;

            using (DbCommand lCommand = lConnection.CreateCommand())
            {
                lCommand.CommandText = "INSERT INTO [Sheet1$]";
                lCommand.CommandText += "([First Name],[Last Name],[Title],[Company],[Address],[Address 2],[City],[State],[Zip],[Country],[Work phone],[Email],[Website],[Stamp Time],[Campaign],[Source],[Business Unit],[Market Segment],[Notes]) ";
                lCommand.CommandText += "VALUES(";
                lCommand.CommandText += "\"" + row["name"].ToString().Replace(" ", " ") + "\",";
                lCommand.CommandText += "\"" + row["lastname"].ToString().Replace(" ", " ") + "\",";
                lCommand.CommandText += "\"" + row["title"].ToString().Replace(" ", " ") + "\",";
                lCommand.CommandText += "\"" + row["company"].ToString().Replace("\"", "\"\"").Replace(" ", " ") + "\",";
                lCommand.CommandText += "\"" + row["address"].ToString().Replace("\"", "\"\"").Replace(" ", " ") + "\",";
                lCommand.CommandText += "\"" + row["address2"].ToString().Replace("\"", "\"\"").Replace(" ", " ") + "\",";
                lCommand.CommandText += "\"" + row["city"].ToString().Replace("\"", "\"\"").Replace(" ", " ") + "\",";
                lCommand.CommandText += "\"" + row["state"].ToString().Replace("\"", "\"\"").Replace(" ", " ") + "\",";
                lCommand.CommandText += "\"" + row["zip"].ToString().Replace("\"", "\"\"").Replace(" ", " ") + "\",";
                lCommand.CommandText += "\"" + row["country"].ToString().Replace("\"", "\"\"").Replace(" ", " ") + "\",";
                lCommand.CommandText += "\"" + row["workphone"].ToString() + "\",";
                lCommand.CommandText += "\"" + row["email"].ToString().Replace("\"", "\"\"").Replace(" ", " ") + "\",";
                lCommand.CommandText += "\"" + row["website"].ToString().Replace("\"", "\"\"").Replace(" ", " ") + "\",";
                lCommand.CommandText += "\"" + row["stamptime"].ToString() + "\",";
                lCommand.CommandText += "\"" + row["campaign"].ToString().Replace("\"","\"\"").Replace(" ", " ") + "\",";
                lCommand.CommandText += "\"" + row["source"].ToString().Replace("\"", "\"\"").Replace(" ", " ") + "\",";
                lCommand.CommandText += "\"" + row["notes"].ToString().Replace("\"", "\"\"").Replace(" ", " ") + "\",";                    
                lCommand.CommandText += "\"" + "High" + "\"";

            lCommand.CommandText += ")";
            lCommand.ExecuteNonQuery();
            }
        }

        lConnection.Close();
    }

所以我想做的是取row["notes"].ToString()并按row["notes"].ToString().Count()对插入进行排序,以便首先插入最长的音符字符串,依此类推。这可能吗?如果是这样我会怎么做呢?

谢谢!

您只需将所有DataView(来自Excel)加载到列表中,然后按行[“notes”]的值对此列表进行排序,即可按所需顺序插入。

   DataView d = null;//Load from Excel
   var rows = (from DataRowView rowView in d select rowView.Row).ToList();
   foreach (DataRow dataRow in rows.OrderByDescending(r=>(int)r["notes"]))
   {
      //Insert code here that you already have
   }
