如何使用 C# 终止进程。 使用简单的方法终止.NET中的现有进程Process.Kill()。有一个可选参数 true 或 false用于结束与要结束的进程相关的所有子进程。
了解如何创建流程。
结束当前进程
System.Diagnostics.Process.GetCurrentProcess().Kill(true);
结束当前计算机上所有名为“notepad”的进程
static void KillAllNotepadProcesses() { System.Diagnostics.Process[] procs System.Diagnostics.Process.GetProcessesByName(notepad, .); // use . for this machine foreach (var proc in procs) proc.Kill(true); }
要结束另一台计算机上名为“notepad”的所有进程
static void KillAllNotepadProcesses() { System.Diagnostics.Process[] procs System.Diagnostics.Process.GetProcessesByName(notepad, Machine-Name-or-IP-Address); // enter the IP address or machine name foreach (var proc in procs) proc.Kill(true); }
结束当前进程的所有其他实例
static void KillAllOtherInstances() { System.Diagnostics.Process thisProc System.Diagnostics.Process.GetCurrentProcess(); System.Diagnostics.Process[] procs System.Diagnostics.Process.GetProcessesByName(thisProc.ProcessName, .); // use . for this machine foreach (var proc in procs) if (proc.Id ! thisProc.Id) // the process Id is unique across all processes while the process name can be common proc.Kill(true); }
完整的现实示例 为了扩展上述代码片段我们准备了以下代码。它使用强力算法来解决π这对 CPU 来说非常耗电。因此它会终止杀死自身的所有其他实例以防止机器负担过重。编译此代码并尝试运行多个实例
