在DataGridView.SelectedCells细胞订单？ [英] Cell order in DataGridView.SelectedCells?

问题描述

我想知道什么是细胞DataGridView.SelectedCells的顺序？我假设了selectedCells [0]将返回第一个单元格（顶部最左边的）和了selectedCells [计数-1]的最后一个（底部最右边的），但奇怪的是有以下四个单元格

[1] [2]
[3] [4]

当我选择这些细胞，并尝试获取单元格值与以下code

 的for（int i = 0; I＆LT; gridView.SelectedCells.Count;我++）
    的MessageBox.show（gridView.SelectedCells [I] .Value.ToString（））;
 

它会显示在错误的顺序值低于

4 2 3 1

我缺少的东西？有DataGridView中的某些属性，指定所选单元格的顺序？请注意，我通过从左上角-大多数细胞拖动光标（具有值1）的底部，最右边的细胞（具有值4）选择的细胞

解决方案

  VAR下令= gridView.SelectedCells.OrderBy（C =＆GT; c.Index）
 

一点点的LINQ to救援:-)这将升序排列细胞的指标进行排序。

I am wondering what is the order of the cells in DataGridView.SelectedCells? I assumed SelectedCells[0] shall return the first cell (top-left-most) and SelectedCells[Count-1] the last (bottom-right-most) but strangely enough with the following four cell grid

[ 1 ] [ 2 ]
[ 3 ] [ 4 ]

when I select these cells and try to get cell values with the following code

for (int i = 0; i < gridView.SelectedCells.Count; i++)
    MessageBox.Show(gridView.SelectedCells[i].Value.ToString());

it displays values in wrong order as below

4 2 3 1

Am I missing something? Is there some property of DataGridView that specifies the ordering of selected cells? Note that I select cells by dragging cursor from top-left-most cell (with value 1) to the bottom-right-most cell (with value 4).

解决方案

var ordered = gridView.SelectedCells.OrderBy(c=>c.Index)

a little LINQ to the rescue :-) This will sort your cells by Index in ascending order.
