Variable parameters in C# Lambda

Question

Is it possible to have a C# lambda/delegate that can take a variable number of parameters that can be invoked with a Dynamic-invoke?

All my attempts to use the \'par

I feel like there's a very crucial point that isn't being discussed here, and that's that if you've defined a delegate type that takes a params argument, there's very little point to calling DynamicInvoke on it at all. The only scenario I can imagine in which this would come into play is if you have a delegate of your custom type and you are passing it as a parameter to some method that accepts a Delegate argument and calls DynamicInvoke on that.

But let's look at this code in the OP's update:

delegate void Foo(params string[] strings);

static void Main(string[] args)                       
{
    Foo x = strings =>
    {
        foreach(string s in strings)
            Console.WriteLine(s);
    };

    x.DynamicInvoke(new[]{new string[]{"1", "2", "3"}});
}

The DynamicInvoke call above is totally superfluous. It would be much more sensible for that last line to read:

x("1", "2", "3");
