apt-get install究竟安装了什么？(What exactly is installed with apt-get install?)

 您需要为每个矩形抓取x / y分钟/最大值，并使用以下值构建矩形： 
 
using System.Linq;
using System.Windows;

internal class Class1
{
    public Class1()
    {
        var rect1 = new Int32Rect(10, 10, 10, 10);
        var rect2 = new Int32Rect(30, 30, 10, 10);
        var rect3 = new Int32Rect(50, 50, 10, 10);
        var rect4 = new Int32Rect(70, 70, 10, 10);

        var int32Rects = new[] { rect1, rect2, rect3, rect4 };
        var int32Rect = GetValue(int32Rects);
    }

    private static Int32Rect GetValue(Int32Rect[] int32Rects)
    {
        int xMin = int32Rects.Min(s => s.X);
        int yMin = int32Rects.Min(s => s.Y);
        int xMax = int32Rects.Max(s => s.X + s.Width);
        int yMax = int32Rects.Max(s => s.Y + s.Height);
        var int32Rect = new Int32Rect(xMin, yMin, xMax - xMin, yMax - yMin);
        return int32Rect;
    }
}
 
 结果： 
 
{10,10,70,70}

You need to grab x/y mins/maxs for each rectangle and build a rectangle out of these values:
 
using System.Linq;
using System.Windows;

internal class Class1
{
    public Class1()
    {
        var rect1 = new Int32Rect(10, 10, 10, 10);
        var rect2 = new Int32Rect(30, 30, 10, 10);
        var rect3 = new Int32Rect(50, 50, 10, 10);
        var rect4 = new Int32Rect(70, 70, 10, 10);

        var int32Rects = new[] { rect1, rect2, rect3, rect4 };
        var int32Rect = GetValue(int32Rects);
    }

    private static Int32Rect GetValue(Int32Rect[] int32Rects)
    {
        int xMin = int32Rects.Min(s => s.X);
        int yMin = int32Rects.Min(s => s.Y);
        int xMax = int32Rects.Max(s => s.X + s.Width);
        int yMax = int32Rects.Max(s => s.Y + s.Height);
        var int32Rect = new Int32Rect(xMin, yMin, xMax - xMin, yMax - yMin);
        return int32Rect;
    }
}
 
Result:
 
{10,10,70,70}
