请详细点

[解决办法]
注意
Form1_Load是Form1.Load事件的代码，选中窗体在属性中事件页找到Load后双击...
listBox1_DrawItem是listBox1.DrawItem事件的代码同上...
最后一次回复，再不能运行就没法说下去了

C# code

private void Form1_Load(object sender, EventArgs e){    listBox1.Items.Add("红色");    listBox1.Items.Add("黄色");    listBox1.Items.Add("蓝色");    listBox1.DrawMode = DrawMode.OwnerDrawFixed; // 属性里设置}private void listBox1_DrawItem(object sender, DrawItemEventArgs e){    Color vColor = e.ForeColor;    switch (e.Index)    {        case 0: vColor = Color.Red; break;        case 1: vColor = Color.Yellow; break;        case 2: vColor = Color.Blue; break;    }    e.Graphics.FillRectangle(new SolidBrush(vColor), e.Bounds);    e.Graphics.DrawString(((ListBox)sender).Items[e.Index].ToString(), e.Font,         new SolidBrush(e.ForeColor), e.Bounds);    e.DrawFocusRectangle();}
