注解

使用此方法创建一个由新 Process 组件构成的数组，并将其与本地计算机上的所有进程资源相关联。进程资源必须已存在于本地计算机上，因为 GetProcesses 不会创建系统资源，而是将资源与应用程序生成的 Process 组件相关联。由于操作系统本身正在运行后台进程，因此此数组永远不会为空。

如果不想检索计算机上运行的所有进程，可以使用或 GetProcessesByName 方法限制其数量GetProcessById。 GetProcessById 创建一个 Process 组件，该组件与系统上由传递给方法的进程标识符标识的进程相关联。 GetProcessesByName 创建一个组件数组， Process 这些组件的关联进程资源共享传递给方法的可执行文件。

注意

可以在服务主机进程 (svchost.exe) 的同一实例中加载多个 Windows 服务。 GetProcesses 不识别这些单独的服务;有关，请参阅 GetServices。
