如何比较datagridview的单元格值 [英] How to compare cell values of datagridview with each other

问题描述

如果我有7行和27列的数据网格视图，如果我需要将单元格的值与其他单元格进行比较怎么做？

详情：

我需要将第1行单元格值与6行单元格值的其余部分进行比较，对于第2行，对于其余5行重复相同的事情，同样需要对第3行进行相同的比较，其余为4行。基本上是行比较

ROW1-> 2 2 2 4 4 6 6 8 8 8 7 7

ROW2-> 1 1 1 7 7 7 6 9 9 9 7 7

ROW3-> 1 1 3 3 3 3 5 5 5 0 0 0

ROW4-> 2 2 2 0 0 0 0 1 1 1 7 7

ROW5-> 0 0 0 3 3 3 4 4 4 8 8 8



现在我想为那些值重复的Cell着色。任何想法对我都有很大的帮助。

If I have a datagridview of say 7 Rows and 27 Columns and if I need to compare the values of cells with another cells how to do it?
Detail:
I need to compare 1st Row cell value with rest of the 6 rows cell values, same thing repeats for 2nd Row for rest 5 row, again same comparison needed for 3rd row with rest 4 rows. Basically It is row wise comparison
ROW1-> 2 2 2 4 4 6 6 8 8 8 7 7
ROW2-> 1 1 1 7 7 7 6 9 9 9 7 7
ROW3-> 1 1 3 3 3 3 5 5 5 0 0 0
ROW4-> 2 2 2 0 0 0 0 1 1 1 7 7
ROW5-> 0 0 0 3 3 3 4 4 4 8 8 8

Now I want to color those Cell whose values are repeating. Any idea will be a great help for me.

推荐答案

for(int comparerRow = 0; comparerRow < rowCount - 1; comparerRow++)
{
    for(int compareeRow = comparerRow + 1; compareeRow < rowCount; compareeRow++)
    {
        for(int columnIndex = 0; columnIndex < columnCount; columnIndex++)
        {
            // Comparison and visual effect
        }
    }
}

重要的标准杆t是内部行循环必须依赖于外部行循环的迭代变量。所以它不会一次又一次地从头开始。

The important part is that the inner row loop has to depend on the outer row loop's iteration variable. So it won't start from the beginning over and over again.
