[antlr-interest] C# issue about action code with generic type.

[Sam Harwell]

In C#, generic type parameters are resolved at compile time. Your code
results in the following:

var _list = new List<"System.String">();

instead of the following valid line:

var _list = new List<System.String>();

One option for your code is using the non-generic ArrayList type. Here's an
additional reference:

Hi, All,

I encounter some troubles when try to embedded action code with generic type
in C#. Here is my case:

 list: LIST_TYPE { var _list = new List<$LIST_TYPE.text>();  }
     ;

My purpose here is getting generic type from LIST_TYPE, and create a generic
list, such as List<string>, List<int> and so on. However, $LIST_TYPE.text
returns a string value, which makes compile failed. Any suggestion?
