C#中怎样将数组的顺序打乱随机排序

//用于存取取出的颜色对象 
List colorList = new List(); 
//通过GetMember获取所有的公共成员 
foreach (var item in typeof(Color).GetMembers()) 
      { 
       //只取属性且为属性中的已知Color，剔除byte属性以及一些布尔属性等（A B G R IsKnownColor Name等） 
          if (item.MemberType == System.Reflection.MemberTypes.Property && System.Drawing.Color.FromName

(item.Name).IsKnownColor == true) 
              { 
                  Color color = System.Drawing.Color.FromName(item.Name); 
                  colorList.Add(color);
               } 
        } 
//转成数组 
Color[] colors = colorList.ToArray();

colors = GetDisruptedItems(colors);

private static Color[] GetDisruptedItems(Color[] colors)
        {
            //生成一个新数组：用于在之上计算和返回
            Color[] temp;
            temp = new Color[colors.Length];
            for (int i = 0; i ) 
            { 
                temp[i] = colors[i];
            }

            //打乱数组中元素顺序
            Random rand = new Random(DateTime.Now.Millisecond);
            for (int i = 0; i )
            {
                int x, y; Color t;
                x = rand.Next(0, temp.Length);
                do
                {
                    y = rand.Next(0, temp.Length);
                } while (y == x);

                t = temp[x];
                temp[x] = temp[y];
                temp[y] = t;
            }

            return temp;

        }
