QueryPack.Criterias
Is a simple abstraction layer that allows for the creation and storage of reusable predicates. This layer implements a fluent criteria builder that builds type-safe expression predicates. These predicates can be used to filter and query data from various data sources, that support LINQ
Getting Started
- Install the package into your project
dotnet add package QueryPack.Criterias
- Create and configure your criteria builder
class EntitySearchBuilder : GenericCriteriaBuilder<Entity, SearchModel>
{
public EntitySearchBuilder()
{
With(m => e => e.Property.StartsWith(m.Property),
r => r.When(m => !string.IsNullOrEmpty(m.Property)));
}
}
- Add the following line to the
Startup
Configure
method.
services.AddCriteriaBuilders(typeof(YourType).Assembly);
- Inject criteria builder into your service and build search criteria
ICriteriaBuilder<Entity, SearchModel> _criteriaBuilder;
Expression<Func<Entity, bool>> criteria = _criteriaBuilder.Build(searchModel);
- Implement an in-memory search using the
UseInMemoryTextSearchBy
extension method.
IEnumerable<Entity> entities;
var results = entities.UseInMemoryTextSearchBy(builder =>
builder.IncludeField(e => e.Property).When(e => !string.IsNullOrEmpty(e.Property)),
new SearchEntity
{
TextSearch = "Test String"
});
- Add in-memory order using the
UseInMemoryOrderBy
extension method
IEnumerable<Entity> entities;
var query = new OrderModel
{
OrderBy = new Dictionary<string, OrderDirection>
{
["fieldA"] = OrderDirection.Asc,
["fieldB"] = OrderDirection.Desc
}
};
var ordered = entities.UseInMemoryOrderBy(query,
optionsConfigurer => optionsConfigurer.AddComparerFactory(new EnumNameComparerFactory()));
- Create a query criteria configuration and inject query visitor
class EntityQueryConfiguration : IQueryConfiguration<Entity, EntityQuery>
{
public void Configure(IQueryCriteriaBuilder<Entity, EntityQuery> builder)
{
builder.AddPredicate(m => e => e.Property.StartsWith(m.SearchProperty),
r => r.When(m => !string.IsNullOrEmpty(m.SearchProperty)));
builder.AddOrder(e => new { e.Property, e.PropertyTwo }, builder => builder.From(e => e.OrderBy));
}
}
var queryModel = new EntityQuery
{
SearchProperty = "search string",
OrderBy = new Dictionary<string, OrderDirection>
{
["Property"] = OrderDirection.Asc,
}
};
IQueryable<Entity> query;
IQueryVisitorBuilder<Entity, EntityQuery> _visitorBuilder;
IQueryVisitor<Entity> visitor = _visitorBuilder.GetVisitor(queryModel);
query = visitor.Visit(query);
