vb.net - Get an item's id from an array and remove it from the array -

so need item's position in array , remove array.

names = {"bob", "jeff", "harry", "carl"} 

i ask "jeff" example , output 1.

i going using item's position remove same position in array. sorting algorithm need code (without array.sort(names) ) if there better way appreciate it.

you can "remove" array, it's not call efficient. have resize array.resize, believe in background recreates it.

dim arrnames string() = {"bob", "jeff", "harry", "carl"} dim snametosearchfor string = "jeff"  integer = 0 arrnames.count - 1     'make sure you're not trying set last value in array     if <> arrnames.count - 1         arrnames(i) = arrnames(arrnames.count - 1)     end if      'resize array removing 1 , exit loop     array.resize(arrnames, arrnames.count - 1)     exit next 

like said, it's not ideal, works.

as alternative, might same above in background...

dim arrnames string() = {"bob", "jeff", "harry", "carl"} dim snametosearchfor string = "jeff" dim nindex integer = array.indexof(arrnames, snametosearchfor)  'if it's -1 didn't find object in array if nindex <> -1     'check see if it's @ end of array     if nindex <> arrnames.count - 1         arrnames(nindex) = arrnames(arrnames.count - 1)     end if      array.resize(arrnames, arrnames.count - 1) end if
