Filename = "Error";
MessageBox.Show( Filename );
}
DirectoryPath =sourceDir.ToString();
DirectoryInfo dir = new DirectoryInfo(DirectoryPath);
FileInfo[] bmpfiles = dir.GetFiles("*.jpg");
foreach (FileInfo f in bmpfiles)
{
string Name = string.Empty;
Name = f.Name.ToString();
Name = Name.Replace(".jpg", "");
foreach (DataRow dr in dt.Rows)

////Filename = Filename + Name;
string Path = string.Empty;
Path = Destdir.ToString()+"\\"+ dr["EmployeeID"].ToString() + ".jpg";
try
{
System.IO.File.Move(f.FullName.ToString(), Path.ToString());
