C＃MySql在C＃中存储多个数据库行

Question

我正在为此苦苦挣扎。我想从数据库中获取某个值等于某行中某个值的ID列表。此调用可能会返回多个ID。我想将值存储在列表或列表中的数组中，但是我发现这很麻烦。我的代码了这里：

 string strConnection = ConfigurationSettings.AppSettings["ConnectionString"]; 
     MySqlConnection connection = new MySqlConnection(strConnection); 
     MySqlCommand command = connection.CreateCommand(); 
     MySqlDataReader reader; 
     command.CommandText = "SELECT idprojects FROM `test`.`projects` WHERE application_layers = " + applicationTiers + ""; 
     connection.Open(); 

     reader = command.ExecuteReader(); 

任何帮助，将不胜感激

 string strConnection = ConfigurationSettings.AppSettings["ConnectionString"]; 
    MySqlConnection connection = new MySqlConnection(strConnection); 

    List<string> array = new List<string>(); 

     using (MySqlCommand cmd = new MySqlCommand("SELECT idprojects FROM `test`.`projects` WHERE application_layers = " + applicationTiers, connection)) 
     { 
      try 
      { 
       using (MySqlDataReader Reader = cmd.ExecuteReader()) 
       { 
        while (Reader.Read()) 
        { 
         array.Add(Reader["idprojects"].ToString()); 
        } 
       } 
      } 

      catch (Exception ex) 
      { 
       throw; 
      } 
     } 

     string[] ret= array.ToArray();
