c# - Filter array of string with select and a bool array -

i need element of string array index in array of bool true. in c#, looking select don't know how utilize on index

string[] contentarray = {"id","name","username"}; bool[] selectionarray = {false,true,false};

i think you're looking for:

ienumerable<string> strings = contentarray.where((str, index) => selectionarray[index]);

which illustration yield ienumerable<string> containing "name".

however, if selectionarray shorter contentarray, index out of bounds exception.

if that's possible, add together length check, assuming want index greater length of selectionarray homecoming false:

ienumerable<string> strings =     contentarray.where(         (str, index) => index < selectionarray.length && selectionarray[index]);
