从C#中的字符串调用函数

using System;

namespace ReflectionExample
{
    class Program
    {
        static void Main(string[] args)
        {
            string methodName = "PrintHelloWorld";
            InvokeMethod(methodName);
        }

        static void InvokeMethod(string methodName)
        {
            Type type = typeof(Program);
            MethodInfo methodInfo = type.GetMethod(methodName);
            if (methodInfo != null)
            {
                methodInfo.Invoke(null, null);
            }
            else
            {
                Console.WriteLine($"Method {methodName} not found.");
            }
        }

        static void PrintHelloWorld()
        {
            Console.WriteLine("Hello, World!");
        }
    }
}
