使用方法做要求输入第一个数字大于第二个数字
static void Main(string[] arr) { int[] shuZi; bool bj = false; while (!bj) { shuZi = Test(); bj = BiJiao(shuZi[0], shuZi[1]); } Console.WriteLine("ok"); Console.ReadKey(); } public static int[] Test() { int n1=0; int n2=0; try { Console.WriteLine("请输入数字1"); n1 = ZhuanHuan(); Console.WriteLine("请输入数字2"); n2 = ZhuanHuan(); } catch { Console.WriteLine("请输入正确的数字"); Test(); } int[] intSz=new int[2]; intSz[0]=n1; intSz[1]=n2; return intSz; } public static int ZhuanHuan() { int numbers = Convert.ToInt32(Console.ReadLine()); return numbers; } public static bool BiJiao(int n1, int n2) { bool bj=false; if (n1 > n2) { bj = true; } return bj; }
