Reflection

•          Reflection is used in the process of obtaining type information at runtime. The classes that give access to the metadata of a running program are in System.Reflection.

•          Reflections is generally used for:

–        Viewing metadata: allows viewing examining attribute information from the code at runtime.

–        Performing type discovery: allows examining the various types in an assembly and instantiate those types.

–        Late binding to methods and properties: allows the developer to call properties and methods on dynamically instantiated objects using discovery.

–        Reflection emit: allows creating new types at runtime and then to use those types to perform tasks.

Using System;

using System.Reflection;

public class MyClass

{

            public virtual int AddNumb(int numb1,int numb2)

            {

                        int result = numb1 + numb2;

                        return result;

            }

}

class MyMainClass

{

            public static int Main()

            {

                        Console.WriteLine ("\nReflection.MethodInfo");

                        // Create MyClass object

                        MyClass myClassObj = new MyClass();

                        // Get the Type information.

                        Type myTypeObj = myClassObj.GetType();

                        // Get Method Information.

                        MethodInfo myMethodInfo = myTypeObj.GetMethod("AddNumb");

                        object[] mParam = new object[] {5, 10};

                        // Get and display the Invoke method.

                        Console.Write("\nFirst method - " + myTypeObj.FullName + " returns " + myMethodInfo.Invoke(myClassObj, mParam) + "\n");

            }

}
