C# How do disable a key
提问by
How do I prevent the caret going to the next line in a text box when the 'ENTER' key has been pressed? In other words how to disable the 'ENTER' or 'RETURN' key in a text-box?
按下“ENTER”键后，如何防止插入符号转到文本框中的下一行？换句话说，如何禁用文本框中的“ENTER”或“RETURN”键？

You can write the OnKeyDownevent. you can use the e.SuppressKeyPressto tell .NET that you handle the key. Something like this:
您可以编写OnKeyDown事件。您可以使用e.SuppressKeyPress告诉 .NET 您处理密钥。像这样的东西：
if (e.KeyCode == Keys.Enter) {
e.SuppressKeyPress = true;
}
