i have an webserivce written where i do an insertion opertion to DB. path :http://localhost:1838/Ajax/WebService.asmx?wsdl.name of the webservice is localhost i have added webservice for the project

now on button click event i try to call this webserice like this localhost obj= new localhost(); obj.insert(); now i am able to do the insertion operation fine.

but i wanted to create an proxy for the webservice so wat is the use of it doing like tat?

when i run this command in my command prompt in vs

wsdl /out:myProxyClass.cs http://localhost:1838/Ajax/WebService.asmx?WSDL

i get an error

1. unable to connect the remote server.

2. no connection would be made because the target machine actively开发者_如何学C refused it

looking forward for an solution any help would great

thank you

It looks like you are using the built in develoment webserver (Cassini). Are you sure it was running when you issued the wsdl command ? The tool needs to connect to the service and download metadata, in order to generate your proxy.
