MethodInfo Class

Provides members that represent a method or constructor. Use the static methods of this class to create MethodInfo objects.

• Invoke Invokes the specified method, using the specified parameters, and return value.
• GetBaseDefinition When overridden in a derived class, returns the MethodInfo for the closest non-abstract method that this method derives from.
• GetCustomAttributes When overridden in a derived class, returns an enumeration of the custom attributes applied to the member and optionally filters by type.
• GetMethodHandle Returns the native method handle.
• GetParameters When overridden in a derived class, returns an array of the parameters of the invoked method, including the return value and any in, out, or ref parameters.
• GetReturnValue Returns information about the return value of the method.
• IsGenericMethod Indicates whether the current method is a generic method.

• Name Gets the name of the current method.
• ReturnType Gets the return type of the current method.
• MethodImplementationFlags Gets the implementation flags for the current method.
• IsSpecialName Gets a value indicating whether the name is special.

The following example demonstrates how to use MethodInfo to get information about a method and invoke it.

using System;
using System.Reflection;

public class Example
{
    public void Greet(string name)
    {
        Console.WriteLine($"Hello, {name}!");
    }

    public static void Main(string[] args)
    {
        Type exampleType = typeof(Example);
        MethodInfo greetMethod = exampleType.GetMethod("Greet");

        if (greetMethod != null)
        {
            Console.WriteLine($"Method Name: {greetMethod.Name}");
            Console.WriteLine($"Return Type: {greetMethod.ReturnType}");

            // Create an instance of the class
            Example instance = new Example();

            // Define parameters
            object[] parameters = { "World" };

            // Invoke the method
            greetMethod.Invoke(instance, parameters);
        }
    }
}
