C# 是否有一种方法可以获取当前列和行索引对，其中矩形在统一的网格上单击，并带有for循环等。？

虽然矩形放置在UniformGrid中，但可以为它们指定Grid.Row和Grid.Column属性：

    private void ToggleGrid(object sender, MouseButtonEventArgs e) //changes color
    {
        if (e.OriginalSource is Shape s)
        {
            cellColumn = (int)GetBoundingBox(s, gameUniformGrid).X;
            cellRow = (int)GetBoundingBox(s, gameUniformGrid).Y;
            rectangle[cellColumn, cellRow].Fill = new SolidColorBrush(Colors.Green);
            //s.Fill = new SolidColorBrush(Colors.Green);
            //cellPosition[y, x] = "Dead";
        }
        MessageBox.Show($"Column Clicked: {cellColumn}, Row Clicked: {cellRow}");
    }

    private static Rect GetBoundingBox(FrameworkElement element, FrameworkElement parent)
    {
        GeneralTransform transform = element.TransformToAncestor(parent);
        Point topLeft = transform.Transform(new Point(0, 0));
        Point bottomRight = transform.Transform(new Point(element.ActualWidth, element.ActualHeight));
        return new Rect(topLeft, bottomRight);
    }
}

然后读它们：

rectangle[x, y] = new Rectangle { Stroke = Brushes.Black, Fill = brush };
rectangle[x, y].SetValue(Grid.RowProperty, x);
rectangle[x, y].SetValue(Grid.ColumnProperty, y);
gameUniformGrid.Children.Add(rectangle[x, y]);

---

使用

Rectangle.Tag

rectangle[x, y] = new Rectangle { Stroke = Brushes.Black, Fill = brush };
rectangle[x, y].SetValue(Grid.RowProperty, x);
rectangle[x, y].SetValue(Grid.ColumnProperty, y);
gameUniformGrid.Children.Add(rectangle[x, y]);

if (e.OriginalSource is Shape s)
{
    cellColumn = (int)s.GetValue(Grid.ColumnProperty);
    cellRow = (int)s.GetValue(Grid.RowProperty);
    rectangle[cellRow, cellColumn].Fill = Brushes.Green;
}
