C# Winform编程ListBox之添加图标

 先上图：

 

这里添加固定的图片的。

代码：

 

private Color RowBackColorAlt=Color.FromArgb(200,200,200);//交替色
private Color RowBackColorSel = Color.FromArgb(150, 200, 250);//选择项目颜色

public Form1()
{
    InitializeComponent();
    listBox1.DrawMode = DrawMode.OwnerDrawFixed;
    listBox1.ItemHeight = 24;
}

private void listBox1_DrawItem(object sender, DrawItemEventArgs e)
{
    Brush myBrush = Brushes.Black;

    if ((e.State & DrawItemState.Selected) == DrawItemState.Selected)
    {
        myBrush = new SolidBrush(RowBackColorSel);
    }
    else if (e.Index % 2 == 0)
    {
        myBrush = new SolidBrush(RowBackColorAlt);
    }
    else
    {
        myBrush = new SolidBrush(Color.White);
    }
    e.Graphics.FillRectangle(myBrush, e.Bounds);
    e.DrawFocusRectangle();//焦点框

    //绘制图标
    Image image = Image.FromFile("images/item.png");
    Graphics g = e.Graphics;
    Rectangle bounds = e.Bounds;
    Rectangle imageRect = new Rectangle(
        bounds.X,
        bounds.Y,
        bounds.Height,
        bounds.Height);
    Rectangle textRect = new Rectangle(
        imageRect.Right,
        bounds.Y,
        bounds.Width - imageRect.Right,
        bounds.Height);

    if (image != null)
    {
        g.DrawImage(
            image,
            imageRect,
            0,
            0,
            image.Width,
            image.Height,
            GraphicsUnit.Pixel);
    }

    //文本
    StringFormat strFormat = new StringFormat();
    //strFormat.Alignment = StringAlignment.Center;
    strFormat.LineAlignment = StringAlignment.Center;
    e.Graphics.DrawString(listBox1.Items[e.Index].ToString(), e.Font, new SolidBrush(e.ForeColor), textRect,strFormat);
}
