防止过程变得无法响应

Question

我的程序必须做一些繁重的计算。由于计算原因，整个过程在几秒钟后没有响应，而CPU使用率保持在20％左右，内存使用率约为100 MB。

有没有一种通用的方法来保持Windows窗体应用程序在进行大量计算时的响应？

Answer 1

您所要做的就是将繁重的计算移动到不同的线程。 以下是documentation的修改示例：

using System;
using System.Threading;

public class ServerClass
{
    // The method that will be called when the thread is started.
    public void HeavyCalculation()
    {
        Console.WriteLine(
            "Heavy Calculation is running on another thread.");

        // Pause for a moment to provide a delay to make
        // threads more apparent.
        Thread.Sleep(3000);
        Console.WriteLine(
            "Heavy Calculation has ended.");
    }
}

public class App
{
    public static void Main()
    {
        ServerClass serverObject = new ServerClass();

        // Create the thread object, passing in the
        // serverObject.InstanceMethod method using a
        // ThreadStart delegate.
        Thread InstanceCaller = new Thread(
            new ThreadStart(serverObject.HeavyCalculation));

        // Start the thread.
        InstanceCaller.Start();

        Console.WriteLine("The Main() thread calls this after "
            + "starting the new InstanceCaller thread.");

    }
}
