【接口】PageA.aspx.cs中调用PageB.aspx.cs内的方法，或是反过来，PageB.aspx.cs中想去调用PageA.aspx.cs内的方法

PageA.aspx.cs

using System.Web;
using System.Web.Compilation;
using System.Web.UI;
using System.Web.UI.WebControls;

public partial class PageA : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {
        string virtuaPath = "~/PageB.aspx";
        Type type = BuildManager.GetCompiledType(virtuaPath);
        Page a = (Page)Activator.CreateInstance(type);
        ((ISayable)a).Say("nihao");
    }

}

using System;
using System.Collections.Generic;

using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using Insus.NET;

{
    protected void Page_Load(object sender, EventArgs e)
    {

    }
    public void Say(string name)
    {
        HttpContext.Current.Response.Write(name);
    }
}

【反射】PageC.aspx.cs中调用PageB.aspx.cs内的方法，或是反过来，PageB.aspx.cs中想去调用PageC.aspx.cs内的方法

PageC.aspx.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Compilation;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Reflection;

public partial class PageC : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {
        string virtuaPath = "~/PageB.aspx";
        Type type = BuildManager.GetCompiledType(virtuaPath);
        MethodInfo mi = type.GetMethod("Say");
            
        Page b = (Page)Activator.CreateInstance(type);
        mi.Invoke(b, new object[] { "Insus.NET" });

    }
}

PageB.aspx.cs,使用反射，b中就可以不用接口
