BackgroundWorker with anonymous methods ?

[M-Dayyan]

Hi,
I'm gonna create a BackgroundWorker with an anonymous method.
I've written the following code :

BackgroundWorker bgw = new BackgroundWorker();
bgw.DoWork += new DoWorkEventHandler(
    () =>
    {
        int i = 0;
        foreach (var item in query2)
        {
            ....
            ....
        }
    }
); 

But Delegate 'System.ComponentModel.DoWorkEventHandler' does not take '0' arguments and I have to pass two objects to the anonymous method : object sender, DoWorkEventArgs e

Could you please guide me, how I can do it ?
Thanks.

you should do exacly what the compiler is asking you to do:

BackgroundWorker bw = new BackgroundWorker();
bw.DoWork += delegate(Object sender, DoWorkEventArgs e)
{
    MessageBox.Show("Hi M-Dayyan!");
};
bw.RunWorkerAsync(); 

there are hundrets of tutorials on anonymus methods and delegates. just google

Thanks my friend,
we could do that like this

bgw.DoWork += new DoWorkEventHandler(
    (s, e1) =>
    {
        int i = 0;
        foreach (var item in query2)
        {
            ....
            ....
        }
    }
);

of course this time I chose the lighter method

but even this is possible:

BackgroundWorker bw = new BackgroundWorker();
bw.DoWork += (sender, e) =>
{
    MessageBox.Show("Hi!");
};
bw.RunWorkerAsync();
