winfrom中ListBox自动滚动到底部，并设置单行文字颜色

滚动可以通过TopIndex来设置：

 private void AddMsg(string msg)
        {
            bool scroll = false;
            if (this.listBox1.TopIndex == this.listBox1.Items.Count - (int)(this.listBox1.Height / this.listBox1.ItemHeight))
                scroll = true;

            this.listBox1.Items.Add(msg);

            if (scroll)
                this.listBox1.TopIndex = this.listBox1.Items.Count - (int)(this.listBox1.Height / this.listBox1.ItemHeight);

            this.listBox1.SelectedIndex = this.listBox1.Items.Count - 1;
        }

颜色主要通过DrawItem方法进行行级重绘

private void listBox1_DrawItem(object sender, DrawItemEventArgs e)
        {
            e.DrawBackground();

            if (e.Index < 0)
            {
                e.DrawFocusRectangle();
                return;
            }

            if (listBox1.Items[e.Index].ToString().Contains("成功"))
            {
                e.Graphics.DrawString(((ListBox)sender).Items[e.Index].ToString(), e.Font, new SolidBrush(Color.Lime), e.Bounds);
            }
            else
            {
                e.Graphics.DrawString(((ListBox)sender).Items[e.Index].ToString(), e.Font, new SolidBrush(e.ForeColor), e.Bounds);
            }

            e.DrawFocusRectangle();
        }
