Question

我搜索了更改我们使用的ListView的标题颜色：

private void listView1_DrawColumnHeader(object sender, DrawListViewColumnHeaderEventArgs e)
{
    e.Graphics.FillRectangle(Brushes.Pink, e.Bounds);
    e.DrawText();
}

我们使用相同的事件来更改ListView的标题样式：

private void listView1_DrawColumnHeader(object sender, DrawListViewColumnHeaderEventArgs e)
{
    using (StringFormat sf = new StringFormat())
    {
        sf.Alignment = StringAlignment.Center;
        e.DrawBackground();

        using (Font headerFont =
            new Font("Microsoft Sans Serif", 9, FontStyle.Bold)) //Font size!!!!
        {
            e.Graphics.DrawString(e.Header.Text, headerFont, 
                Brushes.Black, e.Bounds, sf);
        }
    }
}

现在我的问题是我想要更改标题颜色和标题样式。所以我这样写：

private void listView1_DrawColumnHeader(object sender, DrawListViewColumnHeaderEventArgs e)
{
    e.Graphics.FillRectangle(Brushes.Pink, e.Bounds);
    e.DrawText();

    using (StringFormat sf = new StringFormat())
    {
        sf.Alignment = StringAlignment.Center;
        e.DrawBackground();

        using (Font headerFont =
            new Font("Microsoft Sans Serif", 9, FontStyle.Bold)) //Font size!!!!
        {
            e.Graphics.DrawString(e.Header.Text, headerFont,
                Brushes.Black, e.Bounds, sf);
        }
    }
}

但是如果我执行此代码，Header将更改为Bold，但Header颜色不会更改。要更改它们（即标题颜色和标题样式）我缺少什么？我不明白。

尝试此操作，即跳过对e.DrawText()和e.DrawBackground()的调用：

private void list_DrawColumnHeader(object sender, DrawListViewColumnHeaderEventArgs e)
{
    using (var sf = new StringFormat())
    {
        sf.Alignment = StringAlignment.Center;

        using (var headerFont = new Font("Microsoft Sans Serif", 9, FontStyle.Bold))
        {
            e.Graphics.FillRectangle(Brushes.Pink, e.Bounds);
            e.Graphics.DrawString(e.Header.Text, headerFont, 
                Brushes.Black, e.Bounds, sf);
        }
    }
}
