C# ComboBox 下拉列表框默认行间距太小了，用下面的代码解决。

public static void Bind(ComboBox list, int itemHeight)
{
    list.DropDownStyle = ComboBoxStyle.DropDownList;
    list.ItemHeight = itemHeight;
    list.DrawMode = DrawMode.OwnerDrawFixed;

    list.DrawItem += new DrawItemEventHandler(delegate(object sender, DrawItemEventArgs e)
    {
        if (e.Index < 0)
        {
            return;
        }
        e.DrawBackground();
        e.DrawFocusRectangle();
        e.Graphics.DrawString(list.Items[e.Index].ToString(), e.Font, new SolidBrush(e.ForeColor), e.Bounds.X, e.Bounds.Y + 3);
    });
}
