mysql用while循环求偶数和_求奇数偶数的和，，利用while循环

static void Main(string[] args)

{

while (true)

{

try

{

Console.Write("请输入一个数：");

int n = Convert.ToInt32(Console.ReadLine());

int i = 1; int s = 0, z = 0;

while (i <= n)

{

if (i % 2 == 1)

{

Console.Write(i + "为奇数");

s = s + i;

}

else

{

Console.WriteLine(i + "为偶数");

z = z + i;

}

i++;

}

Console.WriteLine("奇数和为" + s);

Console.WriteLine("偶数和为" + z);

}

catch (Exception)

{

Console.WriteLine("请输入正确的数字");

}

finally

{

Console.WriteLine("约里克");

}

}Console.ReadLine();

}
