如何防止文本编辑框在按下 Enter 键时发出蜂鸣声？
我正在开发的 Windows 窗体 C# 应用程序中有一个文本编辑字段，在该功能发生后，窗口会发出叮当声。我找到了一些解决方案，但它仅适用于 C++，我不知道如何将其转换为零，因为它是 char 和非法转换，即使我手动将其转换为 char，它仍然会发出蜂鸣声。
非常感谢任何帮助！
private void txtPhrase_KeyPress(object sender, KeyPressEventArgs e)
{
if (e.KeyChar == (char)13)
{
// keyPress seems to initiate the system beep. Why?
btnSpeak_Click(sender, e);
}
}
I have a text edit field in a Windows Form C# application I am developing and after the function occurs, windows dings. I found some solutions but it applied only to C++ and I couldn't figure how to translate it making the key event to zero since it is a char and illegal cast, even if i do manually cast it to char, it still beeps.
Any help is greatly appreciated!
private void txtPhrase_KeyPress(object sender, KeyPressEventArgs e)

{

}

您必须防止击键到达本机控件。设置 e.Handled = true
You have to prevent the keystroke from reaching the native control. Set e.Handled = true
