如何在条件语句中重构相似的代码？

Question

我想重构这段big肿的代码，我觉得有更好的方法来重写它。有人知道怎么做吗？

if (ls.SelectedIndex == 1) { grid1.Visibility = Visibility.Visible; }
...
if (ls.SelectedIndex == 58) { grid58.Visibility = Visibility.Visible; }

Answer 1

创建网格数组

var gridArray = new Grid[N];

填写：

gridArray[1] = grid1;
gridArray[2] = grid2;
...

使用：

gridArray[ls.SelectedIndex].Visibility = Visibility.Visible;
