声明：题目部分为akoj题目，代码为本人AC代码。
因为本人学校的oj支持各种环境，非常正常的当中就包括了C#。然暑假在家较为空暇，本着学习C#和复习算法的态度和目的，就又開始折腾起oj了。
题目部分是最基础的A+B系列，来看看C#的输入输出是怎么一回事吧

Description
Your task is to Calculate a + b.
Too easy?
! Of course! I specially designed the problem for acm beginners.
You must have found that some problems have the same titles with this one, yes, all these problems were designed for the same aim.
Input
The input will consist of a series of pairs of integers a and b, separated by a space, one pair of integers per line.
Output
For each pair of input integers a and b you should output the sum of a and b in one line, and with one line of output for each line in input.
Sample Input
1 5 10 20
Sample Output
6 30
Source
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
namespace AK1064
{
class Program
{
static void Main(string[] args)
{
string sb;
while ((sb = Console.ReadLine()) != null)
{
string[] s = sb.Split();
int x = int.Parse(s[0]), y = int.Parse(s[1]);
Console.WriteLine(x + y);
}
}
}
}
C#的输入系统非常恶心。仅仅能一行一行读，然后分离出里面的数据。再转换成你想要的类型，然后才干处理

Description
Your task is to Calculate a + b.
Input
Input contains an integer N in the first line, and then N lines follow. Each line consists of a pair of integers a and b, separated by a space, one pair of integers per line.
Output
For each pair of input integers a and b you should output the sum of a and b in one line, and with one line of output for each line in input.
Sample Input

int x = int.Parse(sb[0]), y = int.Parse(sb[1]);
Console.WriteLine(x + y);
}
}

和前一个几乎相同吧，哈哈，本来这几道题就几乎相同

Description
Your task is to Calculate the sum of some integers.
Input
Input contains multiple test cases. Each test case contains a integer N, and then N integers follow in the same line. A test case starting with 0 terminates the input and this test case is not to
be processed.
Output
For each group of input integers you should output their sum in one line, and with one line of output for each line in input.
Sample Input
4 1 2 3 4 5 1 2 3 4 5 0
Sample Output
10 15
Source
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

class Program
{
static void Main(string[] args)
{
string sb;
while ((sb = Console.ReadLine()) != null)
{
string[] s = sb.Split();
int n = int.Parse(s[0]);
if (n == 0) break;
int sum = 0;
for (int i = 1; i <= n; i++)
sum += int.Parse(s[i]);
Console.WriteLine(sum);
}
}
}
}
注意注意，这道题代码一直RE，表示后面有一道和这就差别个输入0结束。可是那道题AC了。这题我猜是输入数据不是严格的在一行输入的。那样的话C#就根本没法读。反正我再看看，以后要是AC了，我就把这句话删掉

OK，C#的写法感觉怎样？也都几乎相同吧。我感觉是这样，和C++、Java都殊途同归，差别就是一些小细节吧能用在刷题上的，在家没书，C#后面的东西没法去看，如今还在不断学习中，加油！
