how to adjust “is a type but is used like a variable”?

Question

I\'m trying to generate some code in a web service. But it\'s returning 2 errors:

1) List is a type but is used like a variable

2) No overload for method \

Answer 1

This

List li = List();

needs to be:

List li = new List();

and you need to create a Customer constructor which takes the 3 arguments you want to pass. The default Customer constructor takes no arguments.
