如何在C#中从字符串创建实例？

using System;

namespace CreateInstanceFromString
{
    class Program
    {
        static void Main(string[] args)
        {
            string className = "MyClass";
            string assemblyName = "MyAssembly";

            // 加载程序集
            Assembly assembly = Assembly.LoadFrom(assemblyName);

            // 创建实例
            object instance = assembly.CreateInstance(className);

            // 调用方法
            MethodInfo methodInfo = instance.GetType().GetMethod("MyMethod");
            methodInfo.Invoke(instance, null);
        }
    }
}
