Question

I have some code I would like to execute very early in the lifecycle of a call to an ASMX function. For our ASPX pages, this code is in the Page_Init() function on a base class, from which all our ASPX pages inherit.

Is there an ASMX equivalent to the ASPX’s Page_Init() function?

Better yet, is there an ASMX lifecycle diagram like the ASPX one? http://msdn.microsoft.com/en-us/library/ms178472.aspx

If there is an ASMX equivalent to Page_Init(), I assume I can implement code in a common base class, from which all my ASMX classes can inherit, correct?

EDIT:
Great responses – thanks for your help!

There isn’t really such a thing in an asmx web service, System.Web.Services.WebService has no events. Your best bet is to create a default constructor and put it in there.

e.g.

    [WebService(Namespace = "http://tempuri.org/")]
    [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
    [System.ComponentModel.ToolboxItem(false)]
    public class WebService1 : System.Web.Services.WebService
    {
        private string strRetVal;

        public WebService1()
        {
            strRetVal = "Hello World";
        }

        [WebMethod]
        public string HelloWorld()
        {
            return strRetVal;
        }
    }
