c# - Filter Entity Framework enumerable on Distinct property -



c# - Filter Entity Framework enumerable on Distinct property -

the next statement not returning distinct values, whole list:

public observablecollection<masterpartslist> parentassemblybom { { var enumerable = this._parentassemblybom .where(parent => parent.isassy == true).distinct(); homecoming new observablecollection<masterpartslist>(enumerable) ; }

truly, should able tell object unique because this._parentassemblybom.partnumber distinct property. how work in logic yield right results?

thanks in advance!

try grouping identifier (in case part number) , select first of group:

var enumerable = this._parentassemblybom .where(parent => parent.isassy == true) .groupby(x => x.partnumber) .select(x => x.firstordefault());

Accessing MATLAB's unicode strings from C -

Accessing MATLAB's unicode strings from C - how can access underlying unicode info of matlab strings through matlab engine or mex c interfaces? here's example. let's set unicode characters in utf-8 encoded file test.txt, read as fid=fopen('test.txt','r','l','utf-8'); s=fscanf(fid, '%s') in matlab. now if first feature('defaultcharacterset', 'utf-8') , c engevalstring(ep, "s") , output text file utf-8. proves matlab stores unicode internally. if mxarraytostring(enggetvariable(ep, "s")) , unicode2native(s, 'latin-1') give me in matlab: non-latin-1 characters replaced character code 26. need getting access underlying unicode info c string in unicode format (utf-8, utf-16, etc.), , preserving non-latin-1 characters. is possible? my platform os x, matlab r2012b. addendum: documentation explicitly states "[mxarraytostring()] supports multibyte encoded characters...
