我该如何推出具有低优先级的进程？ C＃ [英] How do I launch a process with low priority? C#

问题描述

我要执行一个cmd行工具来处理数据。它并不需要被阻断。
我希望它是低优先级。所以我写了下面的

I want to execute a cmd line tool to process data. It does not need to be blocking. I want it to be low priority. So I wrote the below

 Process app = new Process();
 app.StartInfo.FileName = @"bin\convert.exe";
 app.StartInfo.Arguments = TheArgs;
 app.PriorityClass = ProcessPriorityClass.BelowNormal;
 app.Start();

不过，我得到的味精System.InvalidOperationException没有过程与此对象关联。为什么？ ？如何正确使用此应用在低优先级

However, I get a System.InvalidOperationException with the msg "No process is associated with this object." Why? How do I properly launch this app in low priority?

PS：如果没有行app.PriorityClass = ProcessPriorityClass.BelowNormal;该应用程序运行正常。

PS: Without the line app.PriorityClass = ProcessPriorityClass.BelowNormal; the app runs fine.

推荐答案

尝试设置的priorityClass在启动的过程。任务管理器以这种方式工作，让您在一个已经运行的进程设置优先级。

Try setting the PriorityClass AFTER you start the process. Task Manager works this way, allowing you to set priority on a process that is already running.
