C # .net web service

I want to create a simple web service, and I want to call this web service from a client program using C # .net. Since I'm a newbie, it's hard for me to do this. can anyone help.

Thanks...

Create a file with the extension asmx. Provide your function to be displayed as [WebMethod].

[WebMethod]
public string HelloWorld()
{
    return "Hello World";
}

from your other application add a web link to the current asmx page. From this link you can call the desired function.

If you just learn about web services, I would recommend giving up the ASMX route WebService// WebMethod. This functionality has been replaced by WCF.
