求C#编程1!+2!+3!+4!+5!
谢谢啦
程序代码：int count = 0;
for (int i = 1; i <= 5; i++)
{
count += i;
}

程序代码： static void Main(string[] args)
{
Console.WriteLine(GetValues(5));
Console.ReadLine();
}
public static int GetValues(int n)
{
int Num = 0;
for (int i = 0; i < n; i++)
{
Num += Foo(n);
}
return Num;
}
public static int Foo(int n)
{
if (n > 0)
{
return Foo(n - 1) * n;
}
else
{
return 0;
}
}

{
int Num = 0;
for (int i = 0; i < n; i++)

return Num;

public static int Foo(int n)
{
if (n > 0)
{
return Foo(n - 1) * n;
}
else
{
return 1;
}
}刚才发快了，没注意判断了，Foo函数，当N<0时，返回1，按理说负数是没有阶乘的！
