I used this code but I am getting the below error

"""The name 'Directories'/'Server' does not exist in the current context (CS0103)
private DataTable GetFilesAndFolders(string virtualDirPath)
{
DataTable filesAndFolders = new DataTable();
filesAndFolders.Columns.Add("Name");
filesAndFolders.Columns.Add("Path");
filesAndFolders.Columns.Add("Type");
string rootPath = Server.MapPath(virtualDirPath);
if (Directory.Exists(rootPath))
{
string[] directories = Directory.GetDirectories(rootPath);
for (int i = 0; i < Directories.Length; i++)
{
DirectoryInfo drinfo = new DirectoryInfo(directories[i]);
DataRow dr = filesAndFolders.NewRow();
dr["Name"] = drinfo.Name;
dr["Path"] = drinfo.FullName;
dr["Type"] = "D";
filesAndFolders.Rows.Add(dr);
}
string[] files = Directory.GetFiles(rootPath);
for (int i = 0; i < files.Length; i++)
{
FileInfo fInfo = new FileInfo(files[i]);
DataRow dr = filesAndFolders.NewRow();
dr["Name"] = fInfo.Name;
dr["Path"] = fInfo.FullName;
dr["Type"] = "F";
filesAndFolders.Rows.Add(dr);
}
return filesAndFolders;
}
return null;

Thank you @Gautam Parmar

GridView1.DataBind(); I am Getting an Error as Doesnot contain definition for databind

Hi,

Please use this method to get directory hirarchy
private List DirSearch(string sDir)
{
    List files = new List();
    try
    {
        foreach (string f in Directory.GetFiles(sDir))
        {
            files.Add(f);
        }
        foreach (string d in Directory.GetDirectories(sDir))
        {
            files.AddRange(DirSearch(d));
        }
    }
    catch (System.Exception excpt)
    {
        MessageBox.Show(excpt.Message);
    }

    return files;
}
Convert into datatable and bind it to gridview
