C# 如何将整数值从数据库接收到文本框中？

我试图从DB接收一个整数值（车辆号）到一个文本框中，以自动填充框。。。我怎么做？请

using (OdbcConnection conexao = new OdbcConnection(con))
            {
                OdbcCommand commandResgVei = new OdbcCommand(textoResgataVeiculo, conexao);
                conexao.Open();

                OdbcDataReader result = commandResgVei.ExecuteReader();
                resultado.Read();
                vehicle_number.Text = ?????????????????????????? // how?
                name.Text = result["name"] as string;


            }

或：

试试这个

vehicle_number.Text =  result["vehicle_number"]!=null? convert.toString( 
result["vehicle_number"]):"";

试试看

 vehicle_number.Text=reader.GetInt32(index);

你想要自动完成文本框还是什么？

Int32.TryParse(text, out parsedInt)

vehicle_number.Text =  result["vehicle_number"]!=null? convert.toString( 
result["vehicle_number"]):"";

vehicle_number.Text = result["vehicle_number"] as string;

 vehicle_number.Text=reader.GetInt32(index);
