Web Service Authentication in ASP.NET (C#)

[mazdotnet]

Hi guys,

I'm writing a web service and I don't know how I can secure it by
forcing our clients to use a username/password. I've used SalesForce
a
lot and they ask for a username/password once and any subsequent
calls
you don't need to authenticate anymore. How can this be done in
asp.net (C#)?
Ex.I make a call
result = Object.Connect (username, password)
all my other calls I would send result in the method???
Thank you
M.

Try this, but be careful - I believe this sends the authentication
credentials in plaintext - if you are exposing your service to the
internet you need to use SSL and/or some other means of thwarting
snoopers:

private YourNameSpace.MyWebServices.Service1 ws;
ws = new YourNameSpace.MyWebServices.Service1();
ws.Credentials = new System.Net.NetworkCredential(\"UserName\",
\"password\");
ws.PreAuthenticate = true;
string s = ws.HelloWorld();
