Hi everyone

In VB6,paramarray parameter is passed using byref,but in VB.NET,using byval.How can I get back the changed value of the paramarray parameter

My work case in vb.net like this
----------------------------------------------------
Function mytestmethod(paramarray byval arg() as object
arg(0)=1
arg(1)="abc
End Functio

Sub mycalling(
dim a as integer=6
dim b as string="xyz
mytestmethod (a,b
msgbox (a
msgbox (b
End Su
----------------------------------------------------
the expected value of a,b is 12,"abc";but it remains 66 or "xyz"

Who can help me

Best regard

Hi Peter,

I think exactly as you tell it your function (what is a sub)

The sample shows you that the byval is a reference of the object.

Sub mytestmethod(byval arg() as object)
arg(0)=12
arg(1)="abc"
End Function
Click to expand...
Sub mycalling()
Dim obj(2) As Object
obj(0) = 66
obj(1) = "xyz"
mytestmethod(obj)
MsgBox(obj(0))
MsgBox(obj(1))
end sub

I hope this helps?
