Sparkdo Specifications
Sparkdo Specifications 是一个实现了规格模式（Specification Pattern）的 .NET 类库。该库提供了一种灵活且可组合的方式来定义业务规则和查询条件。
功能特性
- 完整的规格模式实现：包括基础规格、组合规格和各种逻辑操作
- LINQ 表达式支持：所有规格都可以转换为 LINQ 表达式，便于与 Entity Framework 等 ORM 集成
- 流畅的 API：通过扩展方法提供链式调用语法
- 高性能：支持表达式组合和参数重绑定，避免常见的 Entity Framework 性能问题
核心组件
基础接口和类
ISpecification<T>：规格的基础接口Specification<T>：规格的抽象基类ExpressionSpecification<T>：从 LINQ 表达式创建的规格AnySpecification<T>：始终返回 true 的规格NoneSpecification<T>：始终返回 false 的规格
组合规格
AndSpecification<T>：AND 组合规格OrSpecification<T>：OR 组合规格NotSpecification<T>：NOT 规格（反转）AndNotSpecification<T>：AND NOT 组合规格
辅助类
SpecificationBuilder：创建规格的便捷方法SpecificationExtensions：规格的扩展方法ExpressionFuncExtender：表达式扩展方法
使用示例
基础用法
// 创建一个简单的规格
var spec = new ExpressionSpecification<Person>(p => p.Age >= 18);
// 检查对象是否满足规格
bool isSatisfied = spec.IsSatisfiedBy(person);
组合规格
// 创建多个规格
var ageSpec = new ExpressionSpecification<Person>(p => p.Age >= 18);
var nameSpec = new ExpressionSpecification<Person>(p => p.Name.StartsWith("A"));
// 组合规格
var combinedSpec = ageSpec.And(nameSpec);
使用 SpecificationBuilder
// 使用便捷方法创建规格
var spec = SpecificationBuilder.PropertyEquals<Person, int>(p => p.Age, 25);
转换为 LINQ 表达式
// 将规格转换为 LINQ 表达式，用于 Entity Framework 查询
var expression = spec.ToExpression();
var adults = context.People.Where(expression);
扩展方法
该库提供了丰富的扩展方法，支持链式调用：
And()：AND 组合Or()：OR 组合AndNot()：AND NOT 组合Not()：NOT 操作（反转）
