我一直在尝试应用来自串行（波特率9600）的簧片数据并写入文本框，而不是将相同的数据写入图形，但它不起作用。它要么不执行任何操作，要么应用程序冻结，直到我的 RAM 耗尽，从我所看到的那一刻起，我连接到我的 arduino（我检查了 arduino IDE，它正确发送了数据）我的 RAM 使用量从 32-50 变为 1GB而且互联网没有任何解决方案我什至找不到同样的问题
这是我的代码

这部分确实不应该有任何评论。为了进行测试，我决定对它们发表评论
我也相信是导致错误的代码块，因为这部分应该将数据写入文本框等。
我无法给出错误，因为我是土耳其人，并用土耳其语给出了主要错误
我尝试更改波特率，但没有成功，因为这只是我被卡住的想法

在此代码中：
当设备成功连接时，ConnectButton_Click 事件处理程序现在开始使用 StartReadingData() 方法异步读取数据。 StartReadingData 方法使用 ReadLineAsync() 方法从串行端口异步连续读取数据。 每当从串行端口接收到新数据时，就会调用 DataReceivedHandler 事件处理程序。在这种情况下，它只是一个占位符，因为我们正在异步处理数据读取。 ProcessData 方法处理接收到的数据并更新 UI。它是使用 BeginInvoke 异步调用的，以从非 UI 线程更新 UI 控件。 WriteToConsole 方法用于将指定颜色的消息写入控制台。
