        { var server = new Server(new ServerConnection { ConnectionString = new SqlConnectionStringBuilder { DataSource = @".\SQLEXPRESS", IntegratedSecurity = true }.ToString() });
                server.ConnectionContext.Connect();var database = server.Databases["ankit"];var output = new StringBuilder();foreach (Table table in database.Tables)
                {var scripter = new Scripter(server) { Options = { ScriptData = true } };var script = scripter.EnumScript(new SqlSmoObject[] { table });foreach (var line in script)
                        output.AppendLine(" "+line);
                } 
                File.WriteAllText(@"D:\ankit.sql", output.ToString());
                MessageBox.Show("Script Created");
        }
    }
