可能有更好的方法來做到這一點,但這有效: 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 以便您可以循環并將特定信息的所有 IP 信息附加到同一行。其余的只是格式化。在一個示例汽車游戲中,我希望能夠讓汽車在屏幕內移動,并且我希望它被邊緣“綁定”。但是,它會不斷剪輯并超出屏幕范圍。我把圖片框做成正方形,并使用汽車圖片的尺寸,它在圖片框中居中)作為代碼模型的基礎。圖片框為 100x100,汽車圖片(側向時)大約為 50x100。例如,如果汽車在屏幕邊緣側向行駛,我會將圖片框的 Y 位置設為 -25。但是,我覺得這太不方便了,因為我可能需要更改汽車的圖片。這段代碼工作得很好,但我覺得它太長了,太不方便了。

如果代碼有效,那么,它可以明確地總結為:
int verticalDirection = Convert.ToInt32(iDirection == CarDirection.UP || iDirection == CarDirection.DOWN);
int horizontalDirection = Convert.ToInt32(iDirection == CarDirection.LEFT || iDirection == CarDirection.RIGHT);
if (pNewLoc.X <= 0)
{
pNewLoc.X = -25 * verticalDirection;
}
else
{
pNewLoc.X = iX + 25 * verticalDirection;
}
if (pNewLoc.Y <= 0)
{
pNewLoc.Y = -25 * horizontalDirection;
}
else
{
pNewLoc.Y = iY + 25 * horizontalDirection;
}
如果您更改圖片的大小,那么您不必使用類似的常量,25而是聲明一個取決于汽車圖片大小的變量。
