Unless you're still stuck on .NET 1.1, you should not use the ArrayList class at all. Use one of the strongly-typed generic collections instead.

ramireddyindia:
you can't pass arraylist. you have to use object arrays.take an object array, pass all those arraylist values into objectlist. then pass that list.

object[] oa = new object[al.length];
for(int vLoop=0; vLoop<al.length; vLoop++)
{
oa[vLoop] = al[vLoop];
}
then pass this oa to webservice.

Hi, I was trying to do your steps.

Dim sc As New ArrayList //dim array list
Dim ArrObj() As Object //create object
ArrObj = sc.ToArray //convert to object AND PASS THIS TO WEB SERVICE.

at the web service method im passing in string as a input parameter.

Public Function DeleteRecord(ByVal EventDetailsID As string) As Integer

didnt work at all.. please kindly help.

thanks

Thank you all....

I preciated...

I also solved this problem by converting the ArrayList to string and send it to webserver as string.

But I believe that the sending by object is better than string.

Thank you so much for helping me...

It's because of the interopability you can't pass ArrayLists via your webmethod, you have to convert you ArrayList to an other type e.g. a object array. For converting look at the ToArray method.
