Visual Studio C#while循环冻结表单应用程序
这是我的密码:Visual Studio C#while循环冻结表单应用程序,c#,C#,这是我的密码: using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Linq; using System.Text; using System.Threading.Tasks; using System.Windows.Forms; using System.Threading; nam
using System;
using System.Collections.Generic;

namespace _8BB_2._0
{
public partial class Form1 : Form
{
public static class globalVars
{
public static bool spacerunning = false;
}
public Form1()
{
InitializeComponent();
globalVars.spacerunning = false;
}
private void button1_Click(object sender, EventArgs e)
{
if (!globalVars.spacerunning)
{
globalVars.spacerunning = true;
while (globalVars.spacerunning)
{
Thread.Sleep(1000);
SendKeys.Send(" ");
}
}
else if (globalVars.spacerunning)
{
globalVars.spacerunning = false;
}
}
}
}
当我点击按钮1时,它开始像它应该的那样每秒点击空格,但当我再次尝试点击它关闭它时,应用程序冻结,它继续按空格。我尝试了多种其他方法,但似乎不知道如何一次做两件事,因为我被锁定在while循环中。调用Thread.Sleep()
将阻塞UI线程。尝试改用异步/等待
private async void button1_Click(object sender, EventArgs e)
{
globalVars.spacerunning = !globalVars.spacerunning;
while (globalVars.spacerunning)
{
await Task.Delay(1000);
SendKeys.Send(" ");
}
}
更新:
您可以使用计时器
public class MainForm : Form
{
private Timer timer = new Timer() { Interval = 1000 };
public MainForm()
{
/* other initializations */
timer.Enabled = false;
timer.Tick += timer_Tick;
}
private void timer_Tick(object sender, EventArgs e)
{
SendKeys.Send(" ");
}
private void button1_Click(object sender, EventArgs e)
{
globalVars.spacerunning = !globalVars.spacerunning;
timer.Enabled = globalVars.spacerunning;
}
}
非常感谢。UI现在可以工作了,但当我点击按钮时它似乎没有停止?这是异步错误还是我的代码错误?代码正常,但如果选择发送空间,则可以按下按钮。
