DynamicNotifyPropertyChanged 1.2.0

This library allows you to create types at runtime that implement INotifyPropertyChanging and INotifyPropertyChanged interfaces. Each property calls OnPropertyChanging and OnPropertyChanged in its setter.

Creating Type

Dynamic class can be created by calling:

Type DynamicNotifyPropertyChangedClassFactory.CreateType(DynamicProperty[] properties)

DynamicProperty contains following properties:

• Name
• Type
• RaisePropertyChanging
• RaisePropertyChanged

By default both OnPropertyChanging and OnPropertyChanged are injected into property setter, but you can disable it by changing RaisePropertyChanging and RaisePropertyChanged values.

You must ensure that duplicate properties are not present. Created type is cached, e.g. if you pass same set of DynamicProperty (even in different order) new type will not be created.

Initializing Created Type

You can create new instance by calling:

object DynamicNotifyPropertyChangedClassFactory.CreateTypeInstance(Type type)

Alternatively, you can create Func that returns new instance by calling:

Func<object> DynamicNotifyPropertyChangedClassFactory.CreateTypeFactory(Type type)

Both methods use caching and Reflection.Emit internally for better performance.

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 object by calling:

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

Both methods have TryGet pattern alternatives.

Setting Property Value

You can set property value by calling:

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

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

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

Both methods have TryGet pattern alternatives.

All methods described above use caching and compiled expressions for better performance.

Batch changes

To improve performance during batch changes you can suspend PropertyChanging, PropertyChanged or both by calling:

IDisposable SuspendPropertyChangingNotifications()

IDisposable SuspendPropertyChangedNotifications(bool raisePropertyChangedOnDispose)

IDisposable SuspendNotifications(bool raisePropertyChangedOnDispose)

After IDisposable is disposed, events will start firing again. If you wish to trigger PropertyChanged for all changed properties after Dispose is called, then set raisePropertyChangedOnDispose to true.
