C# 通过文本框显示文本文件中的单词？

我的代码只是读取文件，将其拆分为单词，然后以0.1秒的频率在文本框中对每个单词进行命名

我点击

“button1”

获取文件并拆分

单击

Start\u按钮后，程序卡住。我看不出代码中有任何问题。有人能看一下吗

我的代码在这里

 public partial class Form1 : Form
    {
        string text1, WordToShow;
        string[] WordsOfFile;
        bool LoopCheck;
        public Form1()
        {
            InitializeComponent();
        }

        private void button1_Click(object sender, EventArgs e)
        {           
            OpenFileDialog BrowseFile1 = new OpenFileDialog();
            BrowseFile1.Title = "Select a text file";
            BrowseFile1.Filter = "Text File |*.txt";
            BrowseFile1.FilterIndex = 1;
            string ContainingFolder = AppDomain.CurrentDomain.BaseDirectory;
            BrowseFile1.InitialDirectory = @ContainingFolder;
            //BrowseFile1.InitialDirectory = @"C:\";
            BrowseFile1.RestoreDirectory = true;
            if (BrowseFile1.ShowDialog() == DialogResult.OK)
            {
                text1 = System.IO.File.ReadAllText(BrowseFile1.FileName);
                WordsOfFile = text1.Split(' ');
                textBox1.Text = text1;
            }
        }

        private void Start_Button_Click(object sender, EventArgs e)
        {
            timer1.Interval = 100;
            timer1.Enabled = true;
            timer1.Start();
            LoopCheck = true;
            try
            {
                while (LoopCheck)
                {
                    foreach (string word in WordsOfFile)
                    {
                        WordToShow = word;
                        Thread.Sleep(1000);
                    }
                }
            }
            catch
            {
                Form2 ErrorPopup = new Form2();
                if (ErrorPopup.ShowDialog() == DialogResult.OK)
                {
                    ErrorPopup.Dispose();
                }
            }

        }

        private void Stop_Button_Click(object sender, EventArgs e)
        {
            LoopCheck = false;
            timer1.Stop();
        }

        private void timer1_Tick(object sender, EventArgs e)
        {
            textBox1.Text = WordToShow;
        }
    }
}

而不是
Thread.Sleep（1000）将
异步/等待
功能与
任务一起使用。延迟
以使您的
用户界面
负责：

private async void Start_Button_Click(object sender, EventArgs e)
    {
        timer1.Interval = 100;
        timer1.Enabled = true;
        timer1.Start();
        LoopCheck = true;
        try
        {
            while (LoopCheck)
            {
                foreach (string word in WordsOfFile)
                {
                    WordToShow = word;
                    await Task.Delay(1000);
                }
            }
        }
        catch
        {
            Form2 ErrorPopup = new Form2();
            if (ErrorPopup.ShowDialog() == DialogResult.OK)
            {
                ErrorPopup.Dispose();
            }
        }

    }

这就解决了问题。非常感谢。但是我不明白为什么会有一个Thread.Sleep（）方法，而我们有这样一个更可靠的方法？
