Problem Statement
The goal is to get the methods of an object, as names, values or both. Some languages offer dynamic methods, which in general can only be inspected if a class' public API includes a way of listing them.
Let's start with the solution:
Step by Step solution about How to resolve the algorithm Reflection/List methods step by step in the C# programming language
The provided C# code utilizes reflection to retrieve information about the methods of a class named TestForMethodReflection
, revealing both public and private methods. Reflection allows you to inspect and modify the behavior of your program at runtime. Here's a detailed explanation of the code:
-
BindingFlags:
BindingFlags
is used to specify the criteria for filtering the methods to be retrieved. The code sets various flags to ensure it retrieves all methods, including both public and private ones, as well as static and instance methods.
-
GetMethods:
typeof(TestForMethodReflection).GetMethods(flags)
retrieves an array ofMethodInfo
objects representing all the methods in theTestForMethodReflection
class. This includes both public and private methods, as well as static and instance methods.
-
Looping Through Methods:
- The code then iterates through the array of
MethodInfo
objects, printing the name of each method to the console usingConsole.WriteLine
.
- The code then iterates through the array of
Here's a breakdown of the methods in the TestForMethodReflection
class:
MyPublicMethod
: A public instance methodMyPrivateMethod
: A private instance methodMyPublicStaticMethod
: A public static methodMyPrivateStaticMethod
: A private static method
By using reflection, you can access information about methods and their parameters, invoke methods dynamically, and even modify the behavior of methods at runtime. This allows for powerful introspection and customization in your code.
Source code in the csharp programming language
using System;
using System.Reflection;
public class Rosetta
{
public static void Main()
{
//Let's get all methods, not just public ones.
BindingFlags flags = BindingFlags.Instance | BindingFlags.Static
| BindingFlags.Public | BindingFlags.NonPublic
| BindingFlags.DeclaredOnly;
foreach (var method in typeof(TestForMethodReflection).GetMethods(flags))
Console.WriteLine(method);
}
class TestForMethodReflection
{
public void MyPublicMethod() {}
private void MyPrivateMethod() {}
public static void MyPublicStaticMethod() {}
private static void MyPrivateStaticMethod() {}
}
}
