but they're not working...
但他们不工作...
When I write something and press Enter, it doesn't work. It only highlights my text.
当我写东西并按 时Enter，它不起作用。它只突出显示我的文字。

Try this code,might work (Assuming windows form):
试试这个代码，可能会工作（假设窗口形式）：
private void CheckEnter(object sender, System.Windows.Forms.KeyPressEventArgs e)
{
if (e.KeyChar == (char)13)
{
// Enter key pressed
}
}
Register the event like this :
像这样注册事件：
this.textBox1.KeyPress += new
System.Windows.Forms.KeyPressEventHandler(CheckEnter);

You must try this in keydown event
您必须在 keydown 事件中尝试此操作
here is the code for that :
这是代码：
private void textBox1_KeyDown(object sender, KeyEventArgs e)
{
if (e.Key == Key.Enter)
{
MessageBox.Show("Enter pressed");
}
}

private void textBox1_KeyPress(object sender, KeyPressEventArgs e)
{
if (e.KeyChar == (char)Keys.Enter)
{
MessageBox.Show("Enter Key Pressed");
}
}
This allows you to choose the specific Key you want, without finding the char value of the key.
这允许您选择所需的特定键，而无需查找键的字符值。

KeyChar is looking for an integer value, so it needs to be converted as follows:
KeyChar 正在寻找一个整数值，因此需要进行如下转换：
private void Form1_KeyPress(object sender, KeyPressEventArgs e)
{
if (e.KeyChar == Convert.ToInt16(Keys.Enter))
{
MessageBox.Show("Testing KeyPress");
}
}
回答by agileDev

{

{
MessageBox.Show("Enter pressed");
}
}
Worked for me.
