Hi,
May I know what is the difference between C# 4.0 and C# 2.0? Is C# 4.0 backward compatible to C# 2.0?
Can I say that C# 4.0 is a superset of C# 2.0 (just like what C++ is to C)?
Thanks.

I’ve run into the problem a few times now: How to pre-authenticate .NET WebRequest calls doing an HTTP call to the server – essentially send authentication credentials on the very first request instead of waiting for a server challenge first? At first glance this sound like it should be easy:…

Man I can't believe this. I'm still mucking around with OFX servers and it drives me absolutely crazy how some these servers are just so unbelievably misconfigured. I've recently hit three different 3 major brokerages which fail HTTP validation with bad or corrupt certificates at least according to…

The dynamic type in C# 4.0 is a welcome addition to the language. One thing I’ve been doing a lot with it is to remove explicit Reflection code that’s often necessary when you ‘dynamically’ need to walk and object hierarchy. In the past I’ve had a number of ReflectionUtils that used string based expressions…

I’ve written quite a bit about Visual FoxPro interoperating with .NET in the past both for ASP.NET interacting with Visual FoxPro COM objects as well as Visual FoxPro calling into .NET code via COM Interop. COM Interop with Visual FoxPro has a number of problems but one of them at least got a lot…

Here’s a nice and simple path utility that I’ve needed in a number of applications: I need to find a relative path based on a base path. So if I’m working in a folder called c:\temp\templates\ and I want to find a relative path for c:\temp\templates\subdir\test.txt I want to receive back subdir\test…

Hi,
This ANTLR example does not parse input "1;" . Can you explain why? It parses "11;".
grammar test;
options
{//language = 'CSharp2';
//language = 'Java';
output=AST;
}
expr : mexpr (PLUS^ mexpr)* SEMI!
;
mexpr
: atom (STAR^ atom)*
;
atom: INT
;
//class csharpTestLexer extends Lexer;…

I have this simple grammar for a C# like syntax. I can't figure out any way to separate fields and methods. All the examples I've seen for parsing C# combine fields and methods in the same rule. I would like to split them up as my synatx is pretty simple.
grammar test;
options
{
language =CSharp2;

(I'm a Noob with Antlr)... I'm having difficulties getting my grammar with StringTemplates. Basically I'm trying to write a little DSL. I can get my grammar the way I want (it parses correctly), but I can't get the generation of the target code to work with templates. So here's a snippet of my grammar:
