做了一个小程序，先提示了不能跨线程操作控件，后来用了
            this.Invoke(new EventHandler(delegate
{
}));
后，运行一样假死，不知道为什么。希望高手能帮帮忙啦，本人也刚学不久，谢了。


namespace WindowsApplication11
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void Search()
        {
            
            this.Invoke(new EventHandler(delegate
            {
                SearchPaht(@"C:\WINDOWS\system32");
                SearchPaht(@"C:\WINDOWS\system32");
                SearchPaht(@"C:\WINDOWS\system32");
                SearchPaht(@"C:\WINDOWS\system32");
                SearchPaht(@"C:\WINDOWS\system32");
                SearchPaht(@"C:\WINDOWS\system32");
                SearchPaht(@"C:\WINDOWS\system32");
                SearchPaht(@"C:\WINDOWS\system32");
                SearchPaht(@"C:\WINDOWS\system32");
                SearchPaht(@"C:\WINDOWS\system32");
                SearchPaht(@"C:\WINDOWS\system32");
                SearchPaht(@"C:\WINDOWS\system32");
                SearchPaht(@"C:\WINDOWS\system32");
                SearchPaht(@"C:\WINDOWS\system32");
                SearchPaht(@"C:\WINDOWS\system32");
                SearchPaht(@"C:\WINDOWS\system32");
                SearchPaht(@"C:\WINDOWS\system32");
                SearchPaht(@"C:\WINDOWS\system32");
            }));
        }

        private void SearchPaht(string path)
        {

            DirectoryInfo di = new DirectoryInfo(path);
            FileInfo[] f = di.GetFiles("*.*");
            listBox1.BeginUpdate();
            foreach (FileInfo file in f)
            {
                listBox1.Items.Add(file.FullName);
            }
            listBox1.EndUpdate();
            DirectoryInfo[] d = di.GetDirectories();
            foreach (DirectoryInfo dir in d)
            {
                listBox1.Items.Add(dir.FullName);
            }
        }
        private void button1_Click(object sender, EventArgs e)
        {
            Thread t = new Thread(new ThreadStart(Search));
            t.Start();
        }
    }
}

附件就是上面那些代码，如果看的乱就麻烦下载下来看一眼吧，小弟现谢过了。

在循环中加个 Application.DoEvents();
        private void Search()
        {
            
                SearchPaht(@"C:\WINDOWS\system32");
                SearchPaht(@"C:\WINDOWS\system32");
                SearchPaht(@"C:\WINDOWS\system32");
                SearchPaht(@"C:\WINDOWS\system32");
                SearchPaht(@"C:\WINDOWS\system32");
                SearchPaht(@"C:\WINDOWS\system32");
                SearchPaht(@"C:\WINDOWS\system32");
                SearchPaht(@"C:\WINDOWS\system32");
                SearchPaht(@"C:\WINDOWS\system32");
                SearchPaht(@"C:\WINDOWS\system32");
                SearchPaht(@"C:\WINDOWS\system32");
                SearchPaht(@"C:\WINDOWS\system32");
                SearchPaht(@"C:\WINDOWS\system32");
                SearchPaht(@"C:\WINDOWS\system32");
                SearchPaht(@"C:\WINDOWS\system32");
                SearchPaht(@"C:\WINDOWS\system32");
                SearchPaht(@"C:\WINDOWS\system32");
                SearchPaht(@"C:\WINDOWS\system32");
        }

        private void SearchPaht(string path)
        {

            DirectoryInfo di = new DirectoryInfo(path);
            FileInfo[] f = di.GetFiles("*.*");
            listBox1.BeginUpdate();
            foreach (FileInfo file in f)
            {
                listBox1.Items.Add(file.FullName);
            }
            listBox1.EndUpdate();
            DirectoryInfo[] d = di.GetDirectories();
            foreach (DirectoryInfo dir in d)
            {
                Application.DoEvents();
                listBox1.Items.Add(dir.FullName);
            }
        }
        private void button1_Click(object sender, EventArgs e)
        {
            Search();
        }

用 Application.DoEvents();速度会有影响。 可以试下直接加入ITEMS


        private void Search()
        {
            
                SearchPaht(@"C:\WINDOWS\system32");
                SearchPaht(@"C:\WINDOWS\system32");
                SearchPaht(@"C:\WINDOWS\system32");
                SearchPaht(@"C:\WINDOWS\system32");
                SearchPaht(@"C:\WINDOWS\system32");
                SearchPaht(@"C:\WINDOWS\system32");
                SearchPaht(@"C:\WINDOWS\system32");
                SearchPaht(@"C:\WINDOWS\system32");
                SearchPaht(@"C:\WINDOWS\system32");
                SearchPaht(@"C:\WINDOWS\system32");
                SearchPaht(@"C:\WINDOWS\system32");
                SearchPaht(@"C:\WINDOWS\system32");
                SearchPaht(@"C:\WINDOWS\system32");
                SearchPaht(@"C:\WINDOWS\system32");
                SearchPaht(@"C:\WINDOWS\system32");
                SearchPaht(@"C:\WINDOWS\system32");
                SearchPaht(@"C:\WINDOWS\system32");
                SearchPaht(@"C:\WINDOWS\system32");
        }

        private void SearchPaht(string path)
        {

            DirectoryInfo di = new DirectoryInfo(path);
            FileInfo[] f = di.GetFiles("*.*");
            Array o_arr;
            o_arr.
            List <string> o_str路径数组=new List<string> ();
            foreach (FileInfo file in f)
            {
                Application.DoEvents();
                o_str路径数组.Add(file.FullName);
            }
            listBox1.Items.AddRange(o_str路径数组.ToArray ());
            o_str路径数组.Clear();
            DirectoryInfo[] d = di.GetDirectories();
            foreach (DirectoryInfo dir in d)
            {
                Application.DoEvents();
                o_str路径数组.Add(dir.FullName);
            }
            listBox1.Items.AddRange(o_str路径数组.ToArray());
        }
        private void button1_Click(object sender, EventArgs e)
        {
            Search();
        }

果然高手，解决了，小弟谢过！
