Hi,
I've created a webservice and when I want to use its methods I instantiate it in the a procedure, call the method, and I finally I dispose it, however I think also it could be okay to instantiate the webservice in the "private void Main_Load(object sender, EventArgs e)" event.
The thing is that if I do it the first way I have to instantiate the webservice every time I need one of its methods but in the other way I have to keep a webservice connected all the time when I use it in a form for example.
I would like to know which of these practices are better or if there's a much better way to do it
Strategy 1
private void btnRead_Click(object sender, EventArgs e)
{
try
{
//Show clock
this.picResult.Image = new Bitmap(pathWait);
Application.DoEvents();
//Connect to webservice
svc = new ForPocketPC.ServiceForPocketPC();
svc.Credentials = new System.Net.NetworkCredential(Settings.UserName, Settings.Password);
svc.AllowAutoRedirect = false;
svc.UserAgent = Settings.UserAgent;
svc.PreAuthenticate = true;
svc.Url = Settings.Url;
svc.Timeout = System.Threading.Timeout.Infinite;
svc.CallMethod();
...
catch (Exception ex)
{
ShowError(ex);
}
finally
{
if (svc != null)
svc.Dispose();
}
}
Strategy 2
private myWebservice svc;
private void Main_Load(object sender, EventArgs e)
{
//Connect to webservice
svc = new ForPocketPC.ServiceForPocketPC();
svc.Credentials = new System.Net.NetworkCredential(Settings.UserName, Settings.Password);
svc.AllowAutoRedirect = false;
svc.UserAgent = Settings.UserAgent;
svc.PreAuthenticate = true;
svc.Url = Settings.Url;
svc.Timeout = System.Threading.Timeout.Infinite;
}
private void btnRead_Click(object sender, EventArgs e)
{
try
{
//Show clock
this.picResult.Image = new Bitmap(pathWait);
Application.DoEvents();
svc.CallMethod();
...
catch (Exception ex)
{
ShowError(ex);
}
}
private void Main_Closing(object sender, CancelEventArgs e)
{
svc.Dispose();
}
Thanks in advance
PD. And thanks to the stackoverflow team for inviting me.
