推荐答案

区域可以由矩形（Rectangle和RectangleF），GraphicsPaths或RegionData组成。区域可以与矩形（Rectangle和RectangleF），GraphicsPaths或其他Region联合。在形成两个或多个区域的联盟的情况下，重要的是使接收区域为空。

Regions can be made up of Rectangles (both Rectangle and RectangleF), GraphicsPaths, or RegionData. A Region can be "unioned" with Rectangles (both Rectangle and RectangleF), GraphicsPaths, or another Region. In the case of forming the Union of two or more Regions, it is important to make the receiving Region empty.

在下面的例子中，我们有一个包含标签的矩形数组。我们想对任何标签上的MouseClick事件作出反应（稍后我们将确定MouseClick发生在哪个标签上）。区域是命中测试的完美数据结构。所以我们想要一个包含构成标签的所有矩形的Region。假设已经填充了标签矩形数组。

In the following example, we have an array of Rectangles that contains labels. We want to react to a MouseClick event on any of the labels (later we would determine on which label the MouseClick occurred). A region is the perfect data structure for hit testing. So we want a Region that contains all of the Rectangles that make up labels. Assume that the array of label Rectangles has already been populated.

Rectangle [ ] label;

// ******************************************* new_label_union

Region new_label_union ( )
    {
    Region  region = new Region ( );

    region.MakeEmpty ( );
    for ( int i = 0; ( i < label.Length ); i++ )
        {
        if ( label [ i ] != null )
            {
            if ( label [ i ] != Rectangle.Empty )
                {
                region.Union ( label [ i ] );
                }
            }
        }

    return ( region );
    }

请注意，一旦我们创建了Region，我们就会将其设为空。虽然Region.Union（Rectangle）不是必需的，但Region.Union（Region）绝对是必需的。所以我总是使用Region.MakeEmpty。

Note that as soon as we create the Region, we make it empty. Although not necessary for Region.Union ( Rectangle ) it is absolutely necessary for Region.Union ( Region ). So I always use Region.MakeEmpty.

希望有所帮助。
