如何将参数传递给通过Assembly.CreateInstance加载的C#插件？

public class MyPlugin
{
    private string _parameter;

    public MyPlugin(string parameter)
    {
        _parameter = parameter;
    }

    public void DoSomething()
    {
        // 使用_parameter进行操作
    }
}

using System;
using System.Reflection;

public class Program
{
    public static void Main()
    {
        string pluginPath = "path/to/plugin.dll";
        string parameter = "Hello, Plugin!";

        Assembly assembly = Assembly.LoadFrom(pluginPath);
        Type pluginType = assembly.GetType("MyPlugin");

        object pluginInstance = Activator.CreateInstance(pluginType, parameter);
        MethodInfo methodInfo = pluginType.GetMethod("DoSomething");

        methodInfo.Invoke(pluginInstance, null);
    }
}
