lambda expression based reflection vs normal reflection
- by bitbonk
What is the difference between normal reflection and the reflection that can be done with lambda expressions such as this (taken form build your own MVVM):
public void NotifyOfPropertyChange<TProperty>(Expression<Func<TProperty>> property)
{
var lambda = (LambdaExpression)property;
MemberExpression memberExpression;
if (lambda.Body is UnaryExpression)
{
var unaryExpression = (UnaryExpression)lambda.Body;
memberExpression = (MemberExpression)unaryExpression.Operand;
}
else memberExpression = (MemberExpression)lambda.Body;
NotifyOfPropertyChange(memberExpression.Member.Name);
}
Is the lambda based reflection just using the normal reflection APIs internally? Or is this something significantly different. What is ther perfomance difference?
