如何將數據庫中的整數值接收到文本框中？

Question

即時通訊嘗試從數據庫接收一個整數值（vehicle_number）到一個文本框中，自動填充框...我該怎麼做？請

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; 


      } 

Answer 1

while(rdr.Read()) 
{ 
    text = rdr["<name>"].ToString(); 
} 

如果你真的需要解析它，那麼你可以嘗試：

reader.GetInt32(/*index*/); 

或：

Int32.TryParse(text, out parsedInt) 

Answer 2

試試這個

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

Answer 3

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

Answer 4

嘗試一下

vehicle_number.Text=reader.GetInt32(index);
