WindowsForm 大樂透 使用C#

-----練習，使用for迴圈-----

         private void btnRun_Click(object sender, EventArgs e)

        {

            int iMin = Convert .ToInt16(txtMin.Text) -1;

            int iMax = Convert .ToInt16(txtMax.Text);

            Random rdResult = new Random();

            int[] iResult = new int[6];

            //array 歸零

            for (int i = 0; i <= 5; i++)

                iResult[i] = 0;

            //存取亂數的變數

            int iNumber;

            for (int i = 0; i <= 5; i++)

            {

                //產生亂數

                iNumber = rdResult.Next(iMin -1, iMax) + 1;

                for (int j = 0; j <= 5;)

                {

                    //若亂數重複

                    if (iNumber == iResult[j])

                    {

                        iNumber = rdResult.Next(iMin -1, iMax) + 1;

                        j = 0;

                    }

                    else

                        j++;

                }

                //沒有重複就塞到array

                iResult[i] = iNumber;

            }

            for (int i = 0; i <= 5; i++)

            {

                //類似Web form 的 FindControl

                (( TextBox)pn1.Controls.Find("txtResult" + i.ToString(), true)[0]).Text

                    = iResult[i].ToString();

            }

        }
