如何在Array中获取数组。 [续]

问题描述

我有一个查询，我想将结果作为数组插入并将其插入单个数组中

我试图在每一天选择不同的行，一周。



ex。

I have a query and I want to insert results as an Arrays and insert it in a single Array
I'm trying to get selected Distinct Rows in each day, for a Week.

ex.

{{A,B,C,D},{A,C,D},{A,B}}

using (var reader = cmd.ExecuteReader())
   {
       while (reader.Read())
            {
                myItems = new Itemset();  //this is where I store items in 1 array
                myDb = new ItemsetCollection();// this is where I want to store multiple
                                                //arrays
                var tmp = reader["Fruit"];
                if (tmp != DBNull.Value)
                  {
                    ListBox1.Items.Add(tmp.ToString());
                  }
                foreach (var items in ListBox1.Items)
                  {
                    myItems.Add(items.ToString());
                  }
                foreach (var items in myItems)
                  {
                    myDb.Add(new Itemset() {items.ToString()});
                  }
                    lbList.Text = string.Join(",\n", myItems.ToArray());
                }
            }

我的代码的结果如下：

苹果，橘子，葡萄，柠檬，苹果，葡萄，苹果，橙子，柠檬。



它远远超出了我的想象。

{{Apple，Orange，Grapes，Lemon}，{Apple，Grapes}，{Apple，Orange，Lemon}}





我需要一个C＃代码在一个数组中插入一组数组。

我试过foreach将它存储在数组中。



我需要的最终结果

The result from my code is this:
Apple, Orange, Grapes, Lemon, Apple, Grapes, Apple, Orange, Lemon.

Its so far from what I want it to become.
{{Apple, Orange, Grapes, Lemon}, {Apple, Grapes}, {Apple,Orange, Lemon}}


I need a C# code to insert a set of arrays in a single Array.
I tried foreach to store it in array.

THE FINAL RESULT I NEED

[Week] | [AllFruits]
  1    | {Apple, Orange, Grapes, Lemon},{Apple, Figs, Lemon}, {Apple, Figs, Grapes, Strawberry},{Grapes, Lychee, Strawberry},{Apple,Orange,Grapes},{Apple,Figs,Grapes,Lychee}

我希望你明白我想要处理什么。

我研究了大部分需要的东西信息只是为了完成这个过程，但我仍然缺少/错过了一些重要的部分。

I hope you understand what I want to process.
I researched most of the needed information just to do this process but still I lack/miss some important part.
