C# windows窗体应用程序发送字符串

我制作了一个tcp/ip聊天windows窗体应用程序，它工作正常，但我想让应用程序自动发送文本，我不希望用户像实时流媒体一样单击发送按钮

我使用的是异步连接

我假设您希望发送用户在完成键入时输入的文本。即使我认为这是一个坏主意，因为它会让你的用户感到困惑，你也可以添加一个计时器来计算用户上一次击键后的时间，如果给定的时间过去了（比如说5秒），它也会调用您的按钮单击所调用的方法来发送字符串。

嘿，我只是想知道该怎么做，我想在编写每个字符串时发送，所以我所做的只是处理文本框的事件，它自己这样做，所以当它发生更改时，它会立即发送：D祝您好运：）

发布一些代码。你想在用户输入时发送文本吗？是：D我会添加代码，只需一秒钟@AbhishekI想在输入时发送字符串，它不是用于发送传感器数据的普通聊天应用程序。
