统计数组相同元素个数的linq语句

string[] strArr=new string[]{"a","a","a","b","b","c"};

现在需要制成表格.

DataTable

PID Quantity
a   3
b   2
c   1 --------------------编程问答--------------------

strArr.GroupBy(x=>x).Select(x=>new{Quantity=x.Count(),PID=x.Key});

--------------------编程问答-------------------- string[] strArr=new string[]{"a","a","a","b","b","c"};

var result = strArr.GroupBy(x => x).Select(x => new { PID = x.Key, Quantity
= x.Count() }); --------------------编程问答--------------------



            string[] strArr = new string[] { "a", "a", "a", "b", "b", "c" };

            var vs = from v in strArr group v by v into p select new {p.Key,num=p.Count()};

            foreach (var v in vs)

            {

                MessageBox.Show(v.Key + ":" + v.num.ToString() + "个");

            }

引用 3 楼的回复:

C# code

            string[] strArr = new string[] { "a", "a", "a", "b", "b", "c" };
            var vs = from v in strArr group v by v into p select new {p.Key,num=p.Count()};
            fore……

补充：.NET技术 ,  LINQ
