如何使图片框沿屏幕边缘移动而不剪裁？

Question

可能有更好的方法来做到这一点，但这有效：

        List<NContainer> nList = new List<NContainer>();

        nList.Add(new NContainer { _HostFqdn = "ab1.corp.com", _HostIp = "192.168.0.2", _Severity = 1, _Issue = "Check 1", _ProtoPort = "TCP_80" });

        nList.Add(new NContainer { _HostFqdn = "ab2.corp.com", _HostIp = "192.168.0.3", _Severity = 2, _Issue = "Check 2", _ProtoPort = "TCP_81" });

        nList.Add(new NContainer { _HostFqdn = "ab3.corp.com", _HostIp = "192.168.0.4", _Severity = 1, _Issue = "Check 2", _ProtoPort = "TCP_82" });

        nList.Add(new NContainer { _HostFqdn = "ab4.corp.com", _HostIp = "192.168.0.5", _Severity = 3, _Issue = "Check 1", _ProtoPort = "TCP_80" });

        nList.Add(new NContainer { _HostFqdn = "ab5.corp.com", _HostIp = "192.168.0.6", _Severity = 3, _Issue = "Check 5", _ProtoPort = "TCP_443" });

        nList.Add(new NContainer { _HostFqdn = "ab6.corp.com", _HostIp = "192.168.0.7", _Severity = 4, _Issue = "Check 1", _ProtoPort = "TCP_80" });

        IEnumerable<NContainer> query = from NContainer vulns in nList

                                 orderby vulns._Issue

                                 where vulns._Severity >= 1

                                 select vulns;

        Console.WriteLine("Group by _Issue");

        var prevIssue = "";

        bool first = true;

        foreach (var vuln in query)

        {

            if (prevIssue != vuln._Issue)

            {

                if (first)

                    first = false;

                else

                    Console.WriteLine("\n");

                Console.WriteLine("\t{0}", vuln._Issue);

                Console.Write("\t");

                prevIssue = vuln._Issue;

            }

        }

基本上使用 Console.Write 而不是 WriteLine 以便您可以循环并将特定信息的所有 IP 信息附加到同一行。其余的只是格式化。在一个示例汽车游戏中，我希望能够让汽车在屏幕内移动，并且我希望它被边缘“绑定”。但是，它会不断剪辑并超出屏幕范围。

我把图片框做成正方形，并使用汽车图片的尺寸，它在图片框中居中）作为代码模型的基础。图片框为 100x100，汽车图片（侧向时）大约为 50x100。例如，如果汽车在屏幕边缘侧向行驶，我会将图片框的 Y 位置设为 -25。但是，我觉得这太不方便了，因为我可能需要更改汽车的图片。

这段代码工作得很好，但我觉得它太长了，太不方便了。

如果代码有效，那么，它可以明确地总结为：int verticalDirection = Convert.ToInt32(iDirection == CarDirection.UP || iDirection == CarDirection.DOWN);int horizontalDirection = Convert.ToInt32(iDirection == CarDirection.LEFT || iDirection == CarDirection.RIGHT);if (pNewLoc.X <= 0){&nbsp; &nbsp; pNewLoc.X = -25 * verticalDirection;}else{&nbsp; &nbsp; pNewLoc.X = iX + 25 * verticalDirection;}if (pNewLoc.Y <= 0){&nbsp; &nbsp; pNewLoc.Y = -25 * horizontalDirection;}else{&nbsp; &nbsp; pNewLoc.Y = iY + 25 * horizontalDirection;}如果您更改图片的大小，那么您不必使用类似的常量，25而是声明一个取决于汽车图片大小的变量。
