從sqlite挑選一個ID到C＃控制檯

Question

即時嘗試做一個程序，您可以從我的sqlite數據庫中選擇一個ID，並通過改變一個列我的問題是使C＃理解我的readline應該是我的ID數據庫

IM做一個字符串值（名爲行）那是我的ReadLine，但我怎麼能告訴C＃是隻是應該的WriteLine的ID =行

sql_con = new SQLiteConnection(@"Data Source=C:\Users\Jebus\test\ConsoleApplication1\ConsoleApplication1\bin\Debug\RytterDatabase;Version=3;New=False;Compress=True;"); 

     sql_con.Open(); 

     string row; 
     row = Console.ReadLine(); 

    SQLiteCommand buycommand = new SQLiteCommand ("SELECT ID,Name FROM rytter"); 
    buycommand.Connection = sql_con; 
    buycommand.Prepare(); 

     buycommand.Parameters.AddWithValue("ID",Int32.Parse(row)); 
     SQLiteDataReader rdr = buycommand.ExecuteReader(); 
      if (rdr.HasRows) 
      { 
      while (rdr.Read()) 

       { 
       Console.WriteLine("{0}\t{1}",rdr.GetInt32(0),rdr.GetString(1)); 
       } 
      }

需要在你的語句中的參數

SQLiteCommand buycommand = new SQLiteCommand ("SELECT ID,Name FROM rytter WHERE ID = @ID"); 

然後將參數值加上適當的參數名稱@ID

buycommand.Parameters.AddWithValue("@ID",Int32.Parse(row));
