Should I invoke the delegate multiple times to pass different parameters to same method?

I have a method to do something based on the input parameter. Now, I want to call the method by adding to the invocation list of a delegate but with different parameters.

is it possible to do without invoking the delegate multiple times?

private delegate void myDel(int a);
private myDel del;

public MainWindow()
{
  InitializeComponent();
  del = delmethod;                
}
private void delmethod(int a)
{
 //Do something
}
private void call_methods()
{
 del(1);
 del(2); 
 del(3);
}

Is this the right way or I have any other options? Please note that , I may want to pass many parameters like this using a loop.

though I referred here, they have solution only for calling different methods but I want for the same method.

I want to transfer data from one database to another by calling the method depending on the parameter

Environment : Windows forms, .Net 3.5

by adding to the invocation list of a delegate but with different parameters.

Possible but ugly. You end up with something like:

del += (x) => delmethod(1);
del += (x) => delmethod(2);
del += (x) => delmethod(3);

del(-1); // Note the -1 is not used

I would go for

private void delmethod(params int[] abc)
{
  //Do something for each item in abc
} 

private void call_methods()
{
   del(1,2,3); //you can call with any number of parameters
}
