Answer 1

ASP.NET 2.0里可以 ，之前非常麻烦
 string[] ArrColor = {"#000000","#FFFFFF","#008000","#800000","#808000",
                           "#000080","#800080","#808080","#FFFF00","#00FF00",
                           "#00FFFF","#FF00FF","#FF0000","#0000FF","#008080",};      for (int i = 0; i < DropDownList1.Items.Count; i++)
      {
        Random rnd = new Random(i * unchecked((int)DateTime.Now.Ticks) + i);
        int r2 = rnd.Next();
        Random rm1 = new Random(r2 * unchecked((int)DateTime.Now.Ticks) + i); ;
        Response.Write(ArrColor[rm1.Next(0, ArrColor.Length)]);
        Random rm2 = new Random(r2 * unchecked((int)DateTime.Now.Ticks) + i); ;
        DropDownList1.Items[i].Attributes.Add("style",
          "background-color:" + ArrColor[rm1.Next(0, ArrColor.Length)] +
          ";color:" + ArrColor[rm2.Next(0, ArrColor.Length)]);
      }
