Submitted by Nidhi, on October 26, 2020 [Last updated : March 22, 2023]

Here, we will print class names and its method names using predefined reflection classes Assembly and MethodInfo.

C# program to print class names created in the program using reflection

The source code to print class names created in the program is given below. The given program is compiled and executed successfully on Microsoft Visual Studio.

//C# program to print class names created in 
//the program using reflection.

using System;
using System.Reflection;

class Sample
{
    int num1;
    int num2;

    public void SetValues(int n1, int n2)
    {
        num1 = n1;
        num2 = n2;
    }

    public void PrintValues()
    {
        Console.WriteLine("Num1 :"+ num1);
        Console.WriteLine("Num2 :"+ num2);
    }
}

class Program
{
    static void Main(string[] args)
    {
        Assembly asm;
        Type[] types; 

        asm     = Assembly.GetExecutingAssembly();
        types   = asm.GetTypes();

        Console.WriteLine("Class Names:");
        foreach (Type classNames in types)
        {
            Console.WriteLine("\t" + classNames.Name);
        }
    }
}

Output

Class Names:
        Sample
        Program

Explanation

Here, we created two classes Sample and Program. And imported the System.Reflection to use Assembly class.

The Program class contains the static method Main(), the Main() method is the entry point for the program.

Here, we created reference asm of assembly class which is initialized with object returned by the GetExecutingAssembly(), and then we get types from the current program assembly and printed the name of classes that are created within the current program.
