Re: How to query n web services

Dear friends,
let's say we have 10 "server-side" web service which return some kind
of data.

I'm using visual studio 2005 and I have a Project - the client -
where I added Web References to those 10 ws.
When I added web references, I wrote 10 different web references name.

So, i.e., I should write

Name01.Service service01 = new Name01.Service();
Name02.Service service02 = new Name02.Service();
Name03.Service service03 = new Name03.Service();
...
and then invoke service01.someMethod...

But let's say that I just have to query a subset of those 10 ws.
The subset is given by strings. (so that I have to invoke only those
ws whose names are specified in the following strings)

string s1 = "Name01";
string s4 = "Name04";
string s7 = "Name07";

I need some way to do

Name01.Service service01 = new Name01.Service();
Name04.Service service04 = new Name04.Service();
Name07.Service service07 = new Name07.Service();

which, certainly is not

s1.Service service01 = new s1.Service();

isn't it?

Thanx a lot for any hint.

bye!

Using Reflection, you can use a string to create an instance of an object and then invoke methods on that instance. Check Reflection on Google.

Note that Reflection is slow, so don't use it for performance-critical operations.
