java - What is reflection and why is it useful? - Stack Overflow
Drawbacks of Reflection. Reflection is powerful, but should not be used indiscriminately. If it is possible to perform an operation without using reflection, then it is preferable to avoid using it. The following concerns should be kept in mind when accessing code via reflection. Performance Overhead
reflection - Cast to a reflected Type in C# - Stack Overflow
the dynamic internally uses reflection. You could use reflection directly to get the Quack method and call it. Case 5: as case 4, but using directly reflection: object objFoo = MakeFoo(); // object MakeFoo(){return new Foo();} Type typeFoo = objFoo.GetType(); // You should check for null values before!
How to dynamically create generic C# object using reflection?
I want to dynamically create TaskA or TaskB using C# reflection (Activator.CreateInstance). However I wouldn't know the type before hand, so I need to dynamically create TaskA based on string like "namespace.TaskA" or "namespace.TaskAB".

C# Reflection: Fastest Way to Update a Property Value?
Is this the fastest way to update a property using reflection? Assume the property is always an int: PropertyInfo counterPropertyInfo = GetProperty(); int value = (int)counterPropertyInfo.GetValue(this, null); counterPropertyInfo.SetValue(this, value + 1, null);
c# - How costly is .NET reflection? - Stack Overflow

c# - Using reflection to get values from properties from a list of a ...
To Get/Set using reflection you need an instance. To loop through the items in the list try this: PropertyInfo piTheList = MyObject.GetType().GetProperty("TheList"); //Gets the properties IList oTheList = piTheList.GetValue(MyObject, null) as IList; //Now that I have the list object I extract the inner class and get the value of the property I want PropertyInfo piTheValue = piTheList ...
Detect if a method was overridden using Reflection (C#)
Faaast! case OverriddenCacheStatus.Overridden: return true; // Value is cached! Faaast! } // We must rebuild cache. // We use a delegate: also if this operation allocates a temporary object // it is a lot faster than using reflection! // Due to "limitations" in C# compiler, we need the type of the delegate!
Using C# reflection to call a constructor - Stack Overflow
@BenVoigt while true, if you refresh you will see a new test where I did add this test case. Even with considering the timing of GetConstructor() call it still is 2/3rds the time of an ACtivator.CreateInstance.
