c# - 将查询检索为字节数组

Question

我正在尝试将查询检索为字节数组。不过，我卡在了代码中。

byte[] temp = QueryFile("SELECT modelFile FROM items WHERE modelName='F_Pants1'");
    public byte[] QueryFile(string queue)
            {
                MySqlCommand command = MySqlCon.CreateCommand();
                MySqlDataReader Reader;
                command.CommandText = queue;
                MySqlCon.Open();
                Reader = command.ExecuteReader();
                byte[] thisrow = new byte[1000];
                while (Reader.Read())
                {
                    for (int i = 0; i < Reader.FieldCount; i++)
                        thisrow[0] = Convert.ToByte(Reader.GetValue(i).ToString());


                }
                thisrow = thisrow.Remove(thisrow.Length - 1, 1);
                MySqlCon.Close();

                return thisrow;

            }

如果有人有答案，我将不胜感激。

你把它弄得有点太复杂了。试试这个:

       try {
         Reader = command.ExecuteReader();
         if (Reader.Read())
          {
              return Reader.GetValue(0) as Byte[];
          }
        } finally {
           MySqlCon.Close();
        }
