一段随机数代码

//将从0到n*n - 1放到一个n*n数组中

public static void TestArray(int dimension, System.Text.StringBuilder sb)

        {

            sb.Append(Environment.NewLine);

            IList<int> results = new List<int>();

            int totalCount = dimension * dimension;

            int curIndex = 0;         

            byte[] guidByte = Guid.NewGuid().ToByteArray();          

            int seed = Environment.TickCount ^ guidByte[0];

            Random randObj = new Random(seed);

            for (int i = 0; i < totalCount; i++)

            {

                curIndex = randObj.Next(i + 1);

                results.Insert(curIndex, i);

            }

            for (int i = 0; i < totalCount; i++)

            {

                if ((i % dimension) == 0)

                {

                    sb.Append(Environment.NewLine);

                }

                sb.AppendFormat("{0}", results[i].ToString().PadRight(10, ' '));           

            }

        }

新手贴，晕倒。

将一组数随机的放到一个数组中，连续执行不带重的，可是新手不易做到的。
