把一个文件夹下所有文件用GridView显示出来

Question

我想把一个文件夹下所有文件用GridView显示出来，发现现有的GridView例子都是用数据源的。是不是GridView不是干这个活的？
或者用什么控件比较好，最好有个小例子。要求前面有一个CheckBox.

Answer 1

                    String strDir = "UpLoadFiles";
                    DataTable FileList = new DataTable();
                    
                       DataRow FileItem;
                    
                       FileList.Columns.Add(new DataColumn("选择", typeof(bool)));
                    FileList.Columns.Add(new DataColumn("文件名", typeof(string)));
                    FileList.Columns.Add(new DataColumn("路径", typeof(string)));
                    FileList.Columns.Add(new DataColumn("大小", typeof(Int32)));
                    FileList.Columns.Add(new DataColumn("上传日期", typeof(DateTime)));
                    string dirPath = Server.MapPath(strDir);
                    DirectoryInfo Dir = new DirectoryInfo(dirPath);
                    FileInfo[] arrFiles = Dir.GetFiles();                    foreach (FileInfo f in arrFiles)
                    {
                        FileItem = FileList.NewRow();
                            FileItem[0] = false;
                        FileItem[0] = f.Name;
                        FileItem[1] = f.FullName;
                        FileItem[2] = f.Length;
                        FileItem[3] = f.CreationTime;
                        FileList.Rows.Add(FileItem);
                       }
                    GridView1.DataSource = new DataView(FileList);
                    GridView1.DataBind();

</asp:GridView>    protected void Page_Load(object sender, EventArgs e)
    {
        if (!IsPostBack)
        {
            DirectoryInfo Dir = new DirectoryInfo(@"E:\DOTNET");
            FileInfo[] f = Dir.GetFiles();            GridView1.DataSource = f;
