string invFolderpath = TextBox1.Text;
string inv_name = txtbox.Text;

DirectoryInfo dirinfo = new DirectoryInfo(invFolderpath);
FileInfo[] filearr = dirinfo.GetFiles();

foreach (FileInfo f1 in filearr)
{

SqlConnection conn = new SqlConnection();

string name = f1.Name;
conn = new SqlConnection(ConfigurationManager.ConnectionStrings["sqlCon"].ToString());//Sql database connection written in web.config file
conn.Open();
SqlCommand cmd;
cmd = new SqlCommand("[sp_Inventory]", conn);
cmd.CommandType = CommandType.StoredProcedure;
SqlParameter p1 = cmd.Parameters.Add("@inv_name", SqlDbType.VarChar, 20);
p1.Value = txtbox.Text;
SqlParameter p2 = cmd.Parameters.Add("@invFolderPath", SqlDbType.VarChar, 20);
p2.Value = invFolderpath;
SqlParameter p3 = cmd.Parameters.Add("@invHasSubFolders", SqlDbType.VarChar, 20);
p3.Value = 1;
SqlParameter p4 = cmd.Parameters.Add("@invFilesCount", SqlDbType.VarChar, 20);
p4.Value = 0;
SqlParameter p5 = cmd.Parameters.Add("@invCreatedBy", SqlDbType.VarChar, 20);
p5.Value = 2;

cmd.ExecuteNonQuery();
            conn.Close();
