I'm looking for a nicer way to invoke methods. The following code is called by:
Fetch(someObject, "GetCustomer", 1).

The ugly thing about this is that the name of the method is passed as a string. Is there a way to support something like:
Fetch(someObject.GetCustomer, 1)?

public DataSet Fetch(GetDataDelegate method, object[] parameters)
{
   // you could async invoke the method here. This is sync for illustration
   method.Invoke(parameters);
}

object[] parameters = new object{ 1 };<br />
Fetch( new GetDataDelegate(someObject.GetCustomer), parameters)

I don't know how to implement a generic delegate that can handle all types of signatures (if this is even possible...).

<br />
public delegate object GenDel<T>(T t);<br />
...<br />
GetCustomerRequest args = new GetCustomerRequest(1, 2, 3);<br />
GenDel<GetCustomerRequest> del = new GenDel<GetCustomerRequest>(repository.GetCustomer);<br />
Customer c = (Customer)Fetch(del, args);<br />
...<br />
public object Fetch(Delegate del, params object[] args)<br />
{<br />
    return del.DynamicInvoke(args);<br />
}<br />

dataGridView1.DataBind();
