C# 让最小化的窗口不最小化,该怎么解决

C# 让最小化的窗口不最小化
简单描述一下：一个窗口正最小化着呢，但是我想要让他弹出来。
这个过程，类似于：我点击任务栏上小框框，然后他就会弹出来。

测试通过，你将代码里面的进程名改成自己的就行了

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using System.Runtime.InteropServices;
using System.Diagnostics;
using System.Threading; 

namespace WindowsFormsApplication1
{
    public partial class Form6 : Form
    {
        public Form6()
        {
            InitializeComponent();
        }

        System.Timers.Timer timer = new System.Timers.Timer(1000);

        private void Form6_Load(object sender, EventArgs e)
        {
            timer.Elapsed += new System.Timers.ElapsedEventHandler(SetNormal);
            timer.AutoReset = true;
        }
        private void button1_Click(object sender, EventArgs e)
        {
            timer.Start();
        }
        private void button2_Click(object sender, EventArgs e)
        {
            timer.Stop();
        }
        
        //向句柄窗体发送消息
        [DllImport("user32.dll")]
        static extern int PostMessage(IntPtr hwnd, int wMsg, int wParam, int lParam);

        // 查找窗口句柄       
        [DllImport("user32.dll")]

        [return: MarshalAs(UnmanagedType.Bool)]
        static extern bool GetWindowPlacement(IntPtr hWnd, ref WINDOWPLACEMENT lpwndpl);

        private struct WINDOWPLACEMENT
        {
            public int length;

        Process[] processs;
        WINDOWPLACEMENT placement = new WINDOWPLACEMENT();
        private void SetNormal(object sender, System.Timers.ElapsedEventArgs e)
        {
            //用记事本程序测试，进程名notepad
            processs = Process.GetProcessesByName("notepad");
            if (processs.Length > 0)
            {
                foreach (Process p in processs)
                {
                    if (p.MainWindowHandle != IntPtr.Zero)
                    {
                        GetWindowPlacement(p.MainWindowHandle, ref placement);
                        if (placement.showCmd == 2) //如果处于最小化状态
                        {
                            IntPtr handle = FindWindow(null, p.MainWindowTitle);
                            ShowWindow(handle, 1); //恢复窗体状态
                        }
                    }
                }
            }
        }        
    }
}

SetNormal事件调整一下，加一个空值判断

private void SetNormal(object sender, System.Timers.ElapsedEventArgs e)
{
	//用记事本程序测试，进程名notepad
	process = Process.GetProcessesByName("notepad");
	if (process == null) return;
	foreach (Process p in process.Where(s => s.MainWindowHandle != IntPtr.Zero))
	{
		GetWindowPlacement(p.MainWindowHandle, ref placement);
		if (placement.showCmd == 2) //如果处于最小化状态
		{
			IntPtr handle = FindWindow(null, p.MainWindowTitle);
			ShowWindow(handle, 1); //恢复窗体状态
		}
	}
}
