如何通過多個COM端口同時讀取

-2

我有幾個氣象站，沒有考慮到控制檯本身的電池電流的軟件。我發現讀取當前控制檯的代碼，但我想同時讀取8個控制檯的當前數據。如何通過多個COM端口同時讀取

現在通過COM端口和傳輸速率數據連接，然後在TXT文件上記錄當前電壓控制檯。如何修復代碼以同時讀取幾個COM端口？

您可以使用每個COM端口，一個單獨的線程的列表。 –

你能告訴我怎麼樣嗎？ –

這是一個有點太大的話題來回答這裏...你必須以某種方式瞭解多線程。 [這可能會讓你開始。]（http://stackoverflow.com/questions/2605966/how-to-create-multiple-threads-in-c-sharp） –

我會爲每個崗位的級別，然後有站像下面的代碼

class Program 
    { 
     const int NUMBER_PORTS = 5; 
     static void Main(string[] args) 
     { 
      for(int i = 0; i < NUMBER_PORTS; i++) 
      { 
       WeatherLoopData newStation = new WeatherLoopData("Com" + (i + 1).ToString()); 
       WeatherLoopData.ports.Add(newStation); 
      } 


     } 
     public class WeatherLoopData 
     { 
      public static List<WeatherLoopData> ports = new List<WeatherLoopData>(); 
      SerialPort port = null; 
      public WeatherLoopData(string portName) 
      { 
       port = new SerialPort(portName); 
      } 
      //enter your code here 

     }
