Question

From what I know, C# allows that only the last parameter of a method is of “variable length”, for example:

T f(A a, params B[] b) allows that if you have A r; .... B x, y, z; .... you can call f like f (r, x, y, z). Why C# doesn’t also define something like:

T f(params A[] a, params B[] b)

Answer 1

Because how would the compiler know when the variable arguments for the first parameter stop?

Pleas tell me what argOne and argTwo should contain inside of the method body:

void Foo( params object[] argOne, params object[] argTwo )
{
    // whatever
} 

Foo( 1, false, "Hello", new object(), 2.3 );
