You could register to the KeyDown-Event of the Textbox, look if the pressed key is Enterand then execute the EventHandler of the button:
您可以注册到Textbox的KeyDown-Event，查看按下的键是否被按下Enter，然后执行按钮的EventHandler：
private void buttonTest_Click(object sender, EventArgs e)
{
MessageBox.Show("Hello World");
}
private void textBoxTest_KeyDown(object sender, KeyEventArgs e)
{
if (e.KeyCode == Keys.Enter)
{
buttonTest_Click(this, new EventArgs());
}
}

You can handle the keydown event of your TextBoxcontrol.
您可以处理TextBox控件的 keydown 事件。
private void textBox1_KeyDown(object sender, KeyEventArgs e)
{
if(e.KeyCode==Keys.Enter)
buttonSearch_Click(sender,e);
}
It works even when the button Visibleproperty is set to false
即使将按钮Visible属性设置为false

Since everybody covered the KeyDownanswers, how about using the IsDefaulton the button?
既然每个人都涵盖了KeyDown答案，那么使用IsDefault按钮上的怎么样？

Alternatively, you could set the .AcceptButton property of your form. Enter will automcatically create a click event.
或者，您可以设置表单的 .AcceptButton 属性。Enter 会自动创建一个点击事件。
this.AcceptButton = this.buttonSearch;

If you're just gonna click the button when Enter was pressed how about this?
如果您只是在按下 Enter 键时单击按钮，那该怎么办？
private void textbox1_KeyDown(object sender, KeyEventArgs e)
{
if (e.KeyCode == Keys.Enter)
{
buttonSearch.PerformClick();
}

If buttonSearch has no code, and only action is to return dialog result then:
如果 buttonSearch 没有代码，并且唯一的操作是返回对话框结果，则：
private void textBox1_KeyDown(object sender, KeyEventArgs e)
{
if (e.KeyCode == Keys.Enter)
DialogResult = DialogResult.OK;
}

There are some cases, when textbox will not handle enter key. I think it may be when you have accept button set on form. In that case, instead of KeyDownevent you should use textbox1_PreviewKeyDown(object sender, PreviewKeyDownEventArgs e)
在某些情况下，文本框不会处理回车键。我认为可能是当您在表单上设置了接受按钮时。在这种情况下，KeyDown您应该使用事件而不是事件textbox1_PreviewKeyDown(object sender, PreviewKeyDownEventArgs e)
