//先上代码，更详细请参考 http://blog.csdn.net/xiaohan2826/article/details/8603015

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

        private void Form1_Load(object sender, EventArgs e)
        {
           //创建列表头（此时处于details选项）
            ColumnHeader ch = new ColumnHeader();
            ch.Text = "文件名";
            ch.Width = 120;
            ch.TextAlign = HorizontalAlignment.Left; //设置列的对齐方式
            this.listView1.Columns.Add(ch);

//或者这样创建列表头
this.listView1.Columns.Add("路径",240,HorizontalAlignment.Left);

this.listView1.Columns.Add("大小", 120, HorizontalAlignment.Left);

this.listView1.Columns.Add("创建时间", 180, HorizontalAlignment.Left);
}

        private void button1_Click(object sender, EventArgs e)

            if (folderBrowserDialog1.ShowDialog()==DialogResult.OK)

                        DirectoryInfo dirinfo = new DirectoryInfo(fsinfo.FullName);       //实例化文件夹信息的dirinfo，他使用的路径是集合fsinfo的路径
                        listView1.Items.Add(dirinfo.Name); //调用文件夹信息中的.name
                        listView1.Items[listView1.Items.Count - 1 ].SubItems.Add(dirinfo.FullName); //在第二列把文件夹信息中的路径给items
                        listView1.Items[listView1.Items.Count - 1 ].SubItems.Add("");
                        listView1.Items[listView1.Items.Count - 1 ].SubItems.Add(dirinfo.CreationTime.ToLongDateString());


                    }
                    else

                        listView1.Items[listView1.Items.Count - 1].SubItems.Add(finfo.CreationTime.ToShortDateString());
