嗨，大家好。任何人都可以幫助我在這段代碼中出了什麼問題？它顯示此錯誤： 錯誤2'Datalogging.MainWindow'沒有包含'SerialWrite'的定義，也沒有找到接受類型'Datalogging.MainWindow'的第一個參數的擴展方法'SerialWrite'（你是否缺少一個using指令或程序集引用？）

錯誤3方法名稱預計

我該怎麼解決呢？請編輯代碼並將其張貼在這裏作爲您的答案，謝謝。

Answer 1

你的方法調用mainWindow.SerialWrite('s');更改爲mainWindow.WriteSerial('s');，以適應方法名在此聲明：

public void WriteSerial(string text) 

你倒這兩個詞。

對於您的「方法名稱預計」，我想它在port_DataReceived。您需要將委託傳遞給該線程，但是您沒有正確執行。

代替

Thread thread = new Thread(new ThreadStart(ThreadExample.ThreadJob(this))); 

（你不能直接傳遞的方法作爲參數，可以只使用函數指針），可以使用此語法來傳遞代表：

Thread thread = new Thread(new ThreadStart(() => ThreadExample.ThreadJob(this))); 

請注意，new TreadStart是多餘的，new Thread(() => ThreadExample.ThreadJob(this));將完成這項工作。
