JorgeCostaMacia.ExpressionConverter

Convert simple LINQ predicate expressions to and from Dictionary<string, string> — handy for serializing filters (query strings, message payloads, storage). Zero dependencies.

dotnet add package JorgeCostaMacia.ExpressionConverter

Usage

using JorgeCostaMacia.ExpressionConverter.Domain;

// Expression -> dictionary
Dictionary<string, string> filter =
    ExpressionConverter.Convert<Order>(x => x.Status == "Open" && x.Amount == 100);
// { ["Status"] = "Open", ["Amount"] = "100" }

// dictionary -> expression
Expression<Func<Order, bool>> predicate =
    ExpressionConverter.ConvertBack<Order>(filter);

Convert expects equality checks combined with &&, with the property on the left and any expression that evaluates to a value on the right (a literal, a captured variable, a computed value). Values are rendered invariant-culture: enums by name, DateTime in round-trip ("O") format, null as an empty string. ConvertBack rebuilds the predicate, converting each string back to the property's type — including Guid, enums, DateTime and Nullable<T> (an empty string maps to null); an empty dictionary yields an always-true predicate.

Point ConvertBack at criteria/DTO types, never at entities. When the dictionary crosses a trust boundary (a message payload, a query string), its keys can name any public property of T — on an entity that would let a caller filter by fields you never meant to expose (a hash, a token) and probe their values. A dedicated criteria type makes its properties the allow-list.

Requirements

One of the following SDKs: .NET 8 / 9 / 10 (.NET 10 recommended).
