You can use lambda expressions:

static void Main( string[] args ) {
    int A = 50, B = 30, C = 17;
    Print( () => A );
    Print( () => B );
    Print( () => C );
}

static void Print( System.Linq.Expressions.Expression> input ) {
    System.Linq.Expressions.LambdaExpression lambda = (System.Linq.Expressions.LambdaExpression)input;
    System.Linq.Expressions.MemberExpression member = (System.Linq.Expressions.MemberExpression)lambda.Body;

    var result = input.Compile()();
    Console.WriteLine( "{0}: {1}", member.Member.Name, result );
}
