dynamics crm 2011 - How to perform an ODATA expand in LinqPad -

-

i'm using linqpad connect odata services on local crm organization , don't know how perform "joins" or traverse relationships using linqpad.

here url

organizationdata.svc/new_locationset?$select=new_state_new_location/new_region$expand=new_state_new_location

which works fine in browser. here i'm doing in linqpad:

from l in new_locationset s in l.new_state_new_location select s.new_region

but i'm getting error:

an expression of type 'linqpad.user.new_state' not allowed in subsequent clause in query expression source type 'system.data.services.client.dataservicequery<linqpad.user.new_location>'.  type inference failed in call 'selectmany'.

any ideas? i've found linqpad odata documentation extremely lacking...

you need project out want expand, e.g.:

from p in products select new {p.name, categoryname = p.category.name}

or

products.select(p => new { p.name, categoryname = p.category.name})

will yield

http://services.odata.org/(s(readwrite))/odata/odata.svc/products()?$expand=category&$select=name,category/name

in linqpad's request log tab.

how copy observablecollection item observablecollection without reference of first collection? here observablecollection item value changes affecting both collections. code private observablecollection<ratemodel> _allmetalrate = new observablecollection<ratemodel>(); private observablecollection<ratemodel> _metalrateondate = new observablecollection<ratemodel>(); public observablecollection<ratemodel> allmetalrate { { return this._allmetalrate; } set { this._allmetalrate = value; notifypropertychanged("metalrate"); } } public observablecollection<ratemodel> metalrateondate { { return this._metalrateondate; } set { this._metalrateondate = value; notifypropertychanged("metalrateondate"); } } foreach (var item in metalrateondate) allmetalrate.add(item); what causing , how can solve it? you need clone object referenced item before it's a...

All overlapping substrings matching a java regex -

-
is there api method returns (possibly overlapping) substrings match regular expression? for example, have text string: string t = 04/31 412-555-1235; , , have pattern: pattern p = new pattern("\\d\\d+"); matches strings of 2 or more characters. the matches are: 04, 31, 412, 555, 1235. how overlapping matches? i want code return: 04, 31, 41, 412, 12, 55, 555, 55, 12, 123, 1235, 23, 235, 35. theoretically should possible -- there obvious o(n^2) algorithm enumerates , checks substrings against pattern. edit rather enumerating substrings, safer use region(int start, int end) method in matcher . checking pattern against separate, extracted substring might change result of match (e.g. if there non-capturing group or word boundary check @ start/end of pattern). edit 2 actually, it's unclear whether region() expect zero-width matches. specification vague, , experiments yield disappointing results. for example: string line = "xx90xx"; strin...
