示例1: RunLINQ
public static void RunLINQ()
{
Stack<MergeField> _index = new Stack<MergeField>();
_index.Push(new MergeField() { index = 1, name = "I" });
_index.Push(new MergeField() { index = 2, name = "I" });
_index.Push(new MergeField() { index = 3, name = "F" });
_index.Push(new MergeField() { index = 4, name = "M" });
_index.Push(new MergeField() { index = 5, name = "I" });
_index.Push(new MergeField() { index = 6, name = "L" });
_index.Push(new MergeField() { index = 7, name = "I" });
_index.Push(new MergeField() { index = 8, name = "K" });
_index.Push(new MergeField() { index = 9, name = "O" });
_index.Push(new MergeField() { index = 10, name = "I" });
//IEnumerable<MergeField>
var groups = _index.GroupBy(mf => mf.name).Where(grp => grp.Count() > 1).Select(grp => grp.Key);
var group = _index.GroupBy(mf => mf.name).Where(grp => grp.Count() == 1).Select(grp => grp.First()).OrderByDescending(mf => mf.index); ;
foreach (MergeField m in group)
{
Console.WriteLine(m.index.ToString() + " : " + m.name);
}
Console.WriteLine("Flags");
