问如何在c#中调用对象列表中方法

EN

namespace project1;

public static class Pjo
{
    List<object> list1 = new List<object>();
    static Pab abstate;
    static Pcd cdstate;
    public static Pab Abstate { get; set; }

        List1.add(Pab);
        Pcd = new Libre();
        List1.add(Pcd);
    }
}

public class process
{
    foreach(var item in Pjo.List1)
    {
        Type type = typeof("project1.Pjo");
        Methodinfo m = type.GetMethod();// i need to invoke Library File Method. Ex:pab1() 
    }
}

namespace Lib
{
    public class Library
    {
        int n1;
        int n2;

        public void Library1()
        {
            int n3;
            n3 = n1 + n2;
        }
    }

        int a1;
