我有一个 ToolStripTextBox（它的名称是 SearchBox），当用户键入某些内容并按 Enter 后，我希望它会将它们带到一个 URL。我已经整理好了 URL 部分，但我需要知道之后会发生什么

Handles SearchBox.{what?}

当用户按下“输入”时，我在智能感知弹出窗口中看不到任何事件。

所以，换句话说，我如何在用户按下回车后执行一个动作？

    Private Sub ToolStripComboBox1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles SearchBox.**?????**

    Dim SearchString As String
    SearchString = SearchBox.Text

    Dim URL As String
    URL = ("https://www.example.com/search.php?&q=" + SearchString)

    Process.Start(URL)
End Sub

得到它：

在文本框的 keyup 事件中按下回车键后消除回车键

不准确，但有帮助。

    Public Sub SearchBox_KeyPress(ByVal sender As Object, ByVal e As KeyEventArgs) Handles SearchBox.KeyDown

    If e.KeyCode = Keys.Enter Then

        Dim SearchString As String
        SearchString = SearchBox.Text

        Dim URL As String
        URL = ("https://www.example.com/search.php?search=" + SearchString)

        Process.Start(URL)

    End If
End Sub

您可以处理 SearchBox_KeyUp 或 SearchBox_KeyPress 事件。

看看这里：

这是我的代码，按任意键会导致 URL 加载！

    Public Sub SearchBox_KeyPress(ByVal sender As Object, ByVal e As KeyPressEventArgs) Handles SearchBox.KeyPress

        Dim messageBoxVB As New System.Text.StringBuilder()
        messageBoxVB.AppendFormat("{0} = {1}", "Enter", e.KeyChar)
        messageBoxVB.AppendLine()


        Dim SearchString As String
        SearchString = SearchBox.Text

        Dim URL As String
        URL = ("https://www.example.com/search.php?search=" + SearchString)

        Process.Start(URL)
    End Sub
End Class

如何检查输入？
