如何转换为LINQ [英] How to Convert to LINQ

问题描述

您好，



请参阅以下内容：

Hello,

Please see below:

int i = 0;
           foreach (DataGridViewRow dgr in this.dataGridView1.Rows)
           {
               dgr.DefaultCellStyle.BackColor = ((i % 2) == 0) ? Color.LightGray : Color.DarkGray;
               i++;
           }

有人能告诉我如何将上面的代码转换成LINQ吗？



非常感谢提前

Can anybody tell me how the above code can be converted into LINQ please?

Many thanks in advance

推荐答案

我能想出的最佳解决方案是



购买ReSharper，并且有一个功能可以将foreach转换为LINQ。



这就是我过去使用过的，现在想念它:(

Best solution I can come up with is

Buy ReSharper, and there is a function to convert foreach into LINQ.

That''s what I have used in the past, and miss it now :(

首先，为什么在LINQ中执行此操作？如果没有它，您所拥有的代码就完成了工作，所以我建议您查看为什么需要更改。



如果你愿意，你可以清理一下：

First, why do this in LINQ? The code you have does the job without it, so I''d suggest taking a look at why it is necessary to change.

If you want to you could clean you line a little:

bool isOddRow = true;
foreach (DataGridViewRow dgr in this.dataGridView1.Rows)
{
    dgr.DefaultCellStyle.BackColor = isOddRow ? Color.LightGray : Color.DarkGray;
    isOddRow = !isOddRow;
}

你可以做的一个积极的改变是利用 AlternatingRowsDefaultCellStyle 和 RowsDefaultCellStyle ，这可能完全使上述冗余，请参阅MSDN示例。

One positive change you could make is to take advantage of AlternatingRowsDefaultCellStyle and RowsDefaultCellStyle, which would probably make the above redundant totally, see MSDN for examples.
