从源代码中触发ComboBox的ComboBox事件

Question

ComboBox.SelectedIndex将触发SelectedIndexChanged事件，是否有方法从代码中触发ComboBox的SelectionChangeCommitted？

    public Form1()
    {
        InitializeComponent();
        string[] cb_items = { "A", "B", "C" };
        comboBox1.Items.AddRange(cb_items);
        comboBox1.SelectedIndex = 1;
        // what code will trigger comboBox_SelectionChangedCommitted from here?
    }

    private void comboBox1_SelectedIndexChanged(object sender, EventArgs e)
    {
        // triggered by comboBox1.SelectedIndex = 1
        textBox1.Text = "Selected " + comboBox1.SelectedItem;
    }

    private void comboBox1_SelectionChangeCommitted(object sender, EventArgs e)
    {
        textBox1.Text = "Committed " + comboBox1.SelectedItem;
    }

Answer 1

文档的内容如下：

“只有当用户更改组合框选择时才引发SelectionChangeCommitted事件.”

文档并不总是正确的，但是如果没有相反的证据，我相信今天。
