writing/generating a LL(1) parser for C# (grammatica?)

Hello,

I'm not sure if this is the right place to ask but I was told it might be.

I want the user of my C# program to be able to enter statements and queries to access a database using simple English sentences which I have defined the grammar for in EBNF format.

I need a C# parser for this grammar that will allow me to determine if the statement entered by the user is valid within the defined grammar, and also, I need to know what terminal symbols were used to classify each word of the input, so that the program can interpret their sentence meaningfully.

I have downloaded Grammatica and ANTLR, but I cannot figure out how to use either of them to generate my C# parser.

I also could not find a decent example showing how to use one of these parsers once it is made.

I would greatly appreciate it if anyone who understands this could help me figure out how to build my parser using either of these parser generators, or direct me to another parser generator that is easier to use, or direct me to a webpage that describes precisely how to go about writing a parser by hand.
