Question

我的程序必须做一些繁重的计算。几秒钟的计算导致整个过程变得无响应，而CPU使用率保持在20％左右，内存使用率保持在100 MB左右。

是否有一种通用方法可以使Windows窗体应用程序在进行大量计算时保持响应速度？

Answer 1

您要做的就是将大量的计算移至其他线程。
这是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.");

    }
}

还有一些其他文档，以防您需要：
https://docs.microsoft.com/en-us/dotnet/standard/threading/using-threads-and-threading
https://www.tutorialspoint.com/csharp/csharp_multithreading.htm

以及在线程中启动函数的简短方法：
C# Call a method in a new thread

防止流程无响应
