C# 应用程序未正确关闭(窗体关闭后仍在内存中运行)

Question

我有一个奇怪的情况，在我关闭主窗体后我的应用程序进程仍然在内存中徘徊，我的 Program.cs 代码如下:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Windows.Forms;
using System.Runtime.InteropServices;
using System.IO;

namespace WindowsFormsApplication1
{
    static class Program
    {    
        [Flags]
        enum MoveFileFlags
        {
            None = 0,
            ReplaceExisting = 1,
            CopyAllowed = 2,
            DelayUntilReboot = 4,
            WriteThrough = 8,
            CreateHardlink = 16,
            FailIfNotTrackable = 32,
        }

        [DllImport("kernel32.dll", SetLastError = true, CharSet = CharSet.Unicode)]
        static extern bool MoveFileEx(
            string lpExistingFileName,
            string lpNewFileName,
            MoveFileFlags dwFlags
        );

        /// <summary>
        /// The main entry point for the application.
        /// </summary>
        [STAThread]
        static void Main()
        {
        string lockFile = "run.dat";
        if (!File.Exists(lockFile))
        {
            // that's a first run after the reboot => create the file
            File.WriteAllText(lockFile, "");

            Application.EnableVisualStyles();
            Application.SetCompatibleTextRenderingDefault(false);
            Application.Run(new Form2());
        }
        else
        {
            // that's a consecutive run      
        }
          Application.Run(new Form1());
        }
    }
}

您应该只有一个 Application.Run 以确保当前线程上只有一个消息循环并避免您所描述的那种问题。
