用linq对数组排序及简单运算

// 初始数组
int[] arr = { 8, 10, 5, 6, 45, 676, 20, 35 };

// 对其按升序排序
var q = arr.OrderBy(s => s);

/// 对其按降序排序
/// var q = arr.OrderByDescending(s => s);


int[] sortArr = q.ToArray();

// 对数组求和
int sum = q.Sum();

// 对数组求平均
double avg = q.Average();

string str = "gfedfdasfdasferwq431241324321ablk";
var query = from s in str orderby s select s;
char[] sortStr = query.ToArray();

string strRes = new string(sortStr);
// 可发现此时 strRes = "111222333444aaabdddeeffffgklqrssw"
