類庫呼叫Winform元件的方法：

首先在類庫中建立一個Logger類如下：

 public static class Logger
   {
    private static int Level = 1;
    public static Action<string> action = default;
​
    public static void LogDebug(string msg) {
      Log(msg, 1);
     }
​
    private static void Log(string msg,int level) {
      if (Level <= level) {
        Console.WriteLine($"{DateTime.Now}:{msg}");
        if (action != default)
         {
          action.BeginInvoke(msg,null,null);
         }
       }    
     }
   }
 

然後在Winfrom端設定action

 private void Form1_Load(object sender, EventArgs e)
 {
  Logger.action = (msg) =>
  {
   listBox1.Invoke(new Action(() =>
                 {
                 listBox1.Items.Add(msg);
                 }));
​
  };
 }然後類庫的程式碼直接呼叫：

Logger.LogDebug()
