DynamicPropertyAccess 1.0.0

This library allows you to get or set values to properties by name. It uses compiled lambdas instead that are cached of reflection and is thread safe.

Getting Property Value

You can get property value by calling:

T ObjectExtensions.GetPropertyValue<T>(this object source, string propertyName)

Alternatively, you can create Func that gets property value from an object by calling:

Func<object, object?> TypeExtensions.GetPropertyGetter(this Type type, string propertyName)

Setting Property Value

You can set property value by calling:

void ObjectExtensions.SetPropertyValue(this object source, string propertyName, object value)

Alternatively, you can create Func that sets property value on an object by calling:

Action<object, object?> TypeExtensions.GetPropertySetter(this Type type, string propertyName)

Both methods have TryGet pattern alternatives.

Benchmarks

You can see benchmark for GetPropertyValue method for this library, DynamicPropertyAccessor, FastMember and Reflection.
Methods with ...Reused suffix create Func/PropertyInfo once and then reuse it in benchmark.

As you can see, GetPropertyValue is slightly slower than available alternatives. This is because of thread safety overhead. On the other hand, reused Func from GetPropertyGetter is significantly faster. Additionally, Reflection is almost as fast on .NET 7+. You can read more about it here.

Conclusions

• Use this library (and reuse Getter/Setter) if:
  • Read/Write operations are frequently performed.
  • Thread safety is important.
• Use other libraries if:
  • Read/Write operations are rarely performed.
  • Thread safety is not a concern.
  • Target framework is .NET Framework, .NET 6 or below.
• Use Reflection if:
  • Target framework is .NET 7+ and Read/Write operations are rarely performed.
