c# - List to Dictionary with incremental keys in one line LINQ statement -

-

i have list:

var items = new list<string>() { "hello", "i value", "bye" };

i want convert dictionary following structure:

var dic = new dictionary<int, string>() {      { 1, "hello" },      { 2, "i value" },      { 3, "bye" } };

as can see, dictionary keys incremental values, should reflect positions of each element in list.

i looking one-line linq statement. this:

var dic = items.todictionary(i => **specify incremental key or element index**, => i);

you can using overload of enumerable.select passes index of element:

var dic = items.select((val, index) => new { index = index, value = val})                .todictionary(i => i.index, => i.value);

i realize question might seem trivial some, it's these types of things find myself fighting quite bit , want make sense of despite seeming losing battle in .net (for me anyway). so, if following: using system.web; ... applicationuser user = system.web.httpcontext.getowincontext().getusermanager<applicationusermanager>().findbyid(system.web.httpcontext.user.identity.getuserid()); that produces error in title , red getowincontext() , error cannot resolve symbol 'getowincontext()' however, if following (remove system.web in front of httpcontext ), works expected (or @ least no errors): using system.web; ... applicationuser user = httpcontext.getowincontext().getusermanager<applicationusermanager>().findbyid(system.web.httpcontext.user.identity.getuserid()); however, if (same line that's working using system.web commented out): //using system.web; ... applicationuser user = httpcontext.getowincontext().getusermana...

there new feature in mercurial 3, called 'graft' (graft local). job of moving change-set different branch. is there way "copy" change-set branch? i interested in in moving stuff qa branch production branch, still need code reside in qa. want copy. found , have tried few things, maybe it'll become clear more tinkering , reading... does have better way of 'cherry picking' change-sets move cross branch (or trunk)??? graft copies changesets, doesn't move them. hg graft (emphasis mine): this command uses mercurial's merge logic copy individual changes other branches without merging branches in history graph. known 'backporting' or 'cherry-picking' . default, graft copy user, date, , description source changesets.
