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
c# - Set value of private field - Stack Overflow
Try this (inspired by Find a private field with Reflection?): var prop = s.GetType().GetField("id", System.Reflection.BindingFlags.NonPublic | System.Reflection.BindingFlags.Instance); prop.SetValue(s, "new value"); My changes were to use the GetField method - you are accessing a field and not a property, and to or NonPublic with Instance.
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# - Find a private field with Reflection? - Stack Overflow
Given this class class Foo { // Want to find _bar with reflection [SomeAttribute] private string _bar; public string BigBar { get { return this._bar; } } } I want to
Reflection class to get all properties of any object
Your propertyInfos array is returning 0 length for one of my classes. Changing the line to be. propertyInfos = thisObject.GetType().GetProperties();
Change private static final field using Java reflection
Reflection is used to change the public static final Boolean.FALSE to refer to the Boolean referred to by Boolean.TRUE; As a result, subsequently whenever a false is autoboxed to Boolean.FALSE, it refers to the same Boolean as the one refered to by Boolean.TRUE; Everything that was "false" now is "true" Related questions
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".
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!
c# - Set object property using reflection - Stack Overflow
Or you could wrap Marc's one liner inside your own extension class: public static class PropertyExtension{ public static void SetPropertyValue(this object obj, string propName, object value) { obj.GetType().GetProperty(propName).SetValue(obj, value, null); } }
Comparing Object properties using reflection - Stack Overflow
The main value of reflection would be to write a general purpose object comparer that could take two instances of any kind of object and compare their public fields and properties. This helps avoid writing repetetive comparison code over and over - but that doesn't seem like the case you're in.
