我正在努力拼凑一个拼凑的CreateJobObject和SetInformationJobObject的工作示例。通过各种Google搜索（包括俄语和中文帖子！），我将以下代码拼凑在一起。我认为JOBOBJECT_BASIC_LIMIT_INFORMATION的定义根据平台（32/64位）而变化。CreateJobObject / AssignProcessToJobObject 似乎 可以工作。SetInformationJobObject失败-错误24或87。
Process myProcess // POPULATED SOMEWHERE ELSE // Create Job & assign this process and another process to the job IntPtr jobHandle = CreateJobObject( null , null ); AssignProcessToJobObject( jobHandle , myProcess.Handle ); AssignProcessToJobObject( jobHandle , Process.GetCurrentProcess().Handle ); // Ensure that killing one process kills the others JOBOBJECT_BASIC_LIMIT_INFORMATION limits = new JOBOBJECT_BASIC_LIMIT_INFORMATION(); limits.LimitFlags = (short)LimitFlags.JOB_OBJECT_LIMIT_KILL_ON_JOB_CLOSE; IntPtr pointerToJobLimitInfo = Marshal.AllocHGlobal( Marshal.SizeOf( limits ) ); Marshal.StructureToPtr( limits , pointerToJobLimitInfo , false ); SetInformationJobObject( job , JOBOBJECTINFOCLASS.JobObjectBasicLimitInformation , pionterToJobLimitInfo , ( uint )Marshal.SizeOf( limits ) ) ...

这可能会晚一点，但仍然如此。
我在这里尝试了所有示例，但是没有人同时在32位和64位模式下为我工作。最后，我需要亲自检查所有签名并创建相应的PInvoke例程。我认为，其他人可能会发现这很有帮助。
