Calling two methods Asynchronously in ASP.NET 2.0

i am trying to call two methods (one is a webservice, other is a method which helps login a user to home page) asynchronously. I dont need them to return any value, as the webservice method is just used for logging and the other has code to authenticate the user and login to home page. I am on asp.NET 2.0

I tried reading many articles who suggested using delagates etc... but i never worked on these. Can any one help me with this. Will appreciate it.

if you don't need to wait for results you can use the ThreadPool.QueueUserWorkItem method like Jon suggested

if you need to pass an argument into your method

string msg = "log message";
WaitCallback firstAction = delegate(object args) 
{ 
  string s = ((object[])args)[0]; 
  webService.LogAccess(s); 
};
ThreadPool.QueueUserWorkItem(firstAction, new object[] {msg});

i generally will setup another method called LogAsync to handle all of the ceremony

void LogAsync(string msg)
{
  WaitCallback firstAction = delegate(object args) 
  { 
    string s = ((object[])args)[0]; 
    webService.LogAccess(s); 
  };
  ThreadPool.QueueUserWorkItem(firstAction, new object[] {msg});
}

If you just want to "fire and forget" then you could just queue thread pool work items:

WaitCallback firstAction = delegate { webService.LogAccess(); };
WaitCallback secondAction = delegate { user.Login(); }

ThreadPool.QueueUserWorkItem(firstAction);
ThreadPool.QueueUserWorkItem(secondAction);
