python - Generating a List of object properties from a pre-existing list VB.Net -


with python background, i've become rather accustomed using lines like

print(" ".join({x.name x in my_list}))

where

{x.name x in my_list}

is list/array containing name property of each of objects in my_list.

i'm looking similar in vb.net, know possible using longer section of code like:

dim str1 = "" each item in mylist    str1 &= item.name & " " next

but i'd prefer simpler solution i'll doing lot, , i've heard there's similar notation possible using linq.

any appreciated.

i think talking ienumerable(of t).select function. can use mapping collection of 1 type collection of type.

dim combinednames string = string.join(" ", mylist.select(function(item) item.name))

so equivalent python's {x.name x in my_list} in vb.net 

dim names = mylist.select(function(item) item.name)  dim builder = new stringbuilder() each name in names     builder.append(name)     builder.append(" ") next  dim allnames = builder.tostring()

notice select function return ienumerable(of t) type.
