Hi Rajesh,
try this sample Code

        private void addParentdirectoryFile(string sourcePath)

        {

            string[] fileNames = Directory.GetFiles(sourcePath);

            foreach (string str in fileNames)

            {

                comboBox1.Items.Add(str);



            }

        }



        private void addValuesintoCombobox(string sourcePath)

        {



                foreach (string subFolders in Directory.GetDirectories(sourcePath,"*",SearchOption.AllDirectories))

                {

                    string[] subFolderfileNames = Directory.GetFiles(subFolders);

                    foreach (string fname in subFolderfileNames)

                    {

                        comboBox1.Items.Add(fname);

                    }

                }

          

        }

Call this method :

 addParentdirectoryFile(<Your Directory>);

            addValuesintoCombobox(<Your Directory>);
