CompiledExpressions 1.0.0-pre.1

CompiledExpressions

Create Compiled Delegates like Setters from Getter expressions

• Any level of nesting member support (i.e. x => x.Prop1.Prop2.Prop3)
• Bind time error and accessibility checking. (i.e. Getters without a Setter or with a private Setter)
• NativeAOT compatible with no run-time reflection.

Usage

Full Sample Project: CompiledExpressions.Sample

1. For a library method, call CompiledExpression.CreateAccessor with a property/field access expression. This returns a CompiledAccessor struct with Get<T, TValue>(T instance) and Set<T, TValue>(T instance, TValue value) methods. The MemberNames property contains an array of the member names in the original expression.

using System;
using System.Linq.Expressions;
using CompiledExpressions;


public static class Example
{
    public static void Bind<T, TValue>(
        T target,
        Expression<Func<T, TValue>> targetMember
    )
    {
        var accessor = CompiledExpression.CreateAccessor(targetMember);
        
        // Get the existing value
        var value = accessor.Get(target);
        
        // Set a new value
        accessor.Set(target, value);
        
        // Get the member names
        var memberNames = accessor.MemberNames; // ["Prop1", "Prop2", "Prop3"]
        
        var memberPath = accessor.FullName; // "Prop1.Prop2.Prop3"
    }
}
