asp.net - Converting a list to an array for a web service -

-

i'm trying convert searchlist in web app list array can consumed in web method. right now, i'm using web reference allows arrays passed , returned. i'd convert list array, looks won't work. i've tried looking online each scenario i've found hasn't been similar enough i'm able solve this. idea on best way this?

web app

protected function searchcustomer()     dim searchlist list(of prxcustomerwebservice1.customer)     dim objcustomerws new prxcustomerwebservice1.customerws      searchlist = cache("customerdata")     'arr = searchlist.toarray     if (ddlsearchspecs.text = "contains")         searchlist = objcustomerws.getcontains(tbsearch.text, ddlsearchfields.text, searchlist)     elseif (ddlsearchspecs.text = "starts with")         searchlist = objcustomerws.getstartswith(tbsearch.text, ddlsearchfields.text, searchlist)     else         searchlist = objcustomerws.getexact(tbsearch.text, ddlsearchfields.text, searchlist)     end if     if searchlist.count = 0         lmessage.text = "no customers found"     end if     return searchlist end function

web method

<webmethod(description:="gets customers contain specific value")> _ public function getcontains(byval sstringcontains string, byval spropertyname string, byval olistofcustomers list(of customer))     olistofcustomers()     return customerfactory.getcontains(sstringcontains, spropertyname, olistofcustomers) end function

logic

  public shared function getcontains(byval sstringcontains string, byval spropertyname string, byval olistofcustomers list(of customer))     dim ocustomerdata new customerdata     dim onewlistofcustomers new list(of customer)     dim iindex integer     dim propertyinfo propertyinfo      propertyinfo = gettype(customer).getproperty(spropertyname)      if isnothing(olistofcustomers) = false andalso olistofcustomers.count > 0         try             iindex = 0 olistofcustomers.count - 1                 if (propertyinfo.getvalue(olistofcustomers.item(iindex)).tostring.trim.tolower.contains(sstringcontains.tolower) = true)                     onewlistofcustomers.add(olistofcustomers.item(iindex))                 end if             next         catch ex exception             return true         end try     end if     return onewlistofcustomers end function
