VB.net 如何编写一个可以返回数组的函数（过程）？

Question

如：登录窗口，用户名为下列表框，里面的数据项需通过一个函数来完成添加，（因为它地方可也需要用到这个功能，所以选择用函数来实现）

Answer 1

public function createstringarr() as string()
return new string(){"d1","d2","d3","d4"}
end function

public function CombList(mytj As String) As String()
dim cmd as new oledbcommand(mytj,conn)
'如果用泛型：
dim lr as new list(of string)
''如果不用泛型
'dim lr as new arraylist()

dbreader=cmd.executereader
while dbreader.read
lr.add dbreader.getstring(0)
end while
conn.close()
dbreader.close()
'如果用泛型：
return lr.toarray()
''如果不用泛型：
'return lr.toarray(GetType(String))
End function

调用：
opendata("reg_user","")
tj="select * from reg_user"
dim arraystring as string() = comblist(tj)
for each s as string in arraystring
cmbuserid.items.add(s)
next
