if (!IsPostBack)

{

string dpath = Server.MapPath(".");

Label1.Text = getsize(dpath).ToString();

}

private int getsize(string dirp)

{

DirectoryInfo mydir = new DirectoryInfo(dirp);

foreach (FileSystemInfo fsi in mydir.GetFileSystemInfos())

{

if (fsi is FileInfo)

{

FileInfo fi = (FileInfo)fsi;

str+=int.Parse(fi.Length.ToString());

}
