How can I solve this issue?

推荐答案

那可能就像侦听TextChanged事件然后在其中执行以下行一样简单:

That could be as simple as listening to TextChanged event and then executing the following line inside it:

txtYourTextBox.Text = txtYourTextBox.Text.Replace(Environment.NewLine, "");

该解决方案虽然涉及一些屏幕闪烁.更好的方法是通过监听KeyDown事件来完全阻止它:

This solution involves some screen flicker though. A better way is to prevent it entirely by listening to KeyDown event:

private void txtYourTextBox_KeyDown(object sender, KeyEventArgs e)
{
    if (e.KeyCode == Keys.Enter)
        e.SuppressKeyPress=true;
}
