C # What does the compiler do to the dynamic object?

Private Static void testmethod () {// dynamic is just a placeholder. Dynamic p1 = new {x = 1, y = 89 }; // access to the X attribute of Dynamic Object P1 is implemented through callsite, and callsite can cache object p1x = p1.x; object p1y = p1.y; // dynamic is just a placeholder. Dynamic P2 = new {x = 1, y = 89, Z = 3}; object P2x = p2.x; object p2y = p2.y; object p2z = p2.z ;}

The following figure shows the general result of compiling C # methods with dynamic calls:

using System;using Microsoft.CSharp.RuntimeBinder;using System.Runtime.CompilerServices;private static void TestMethod(){    object p1 = new {        X = 1,        Y = 0x59    };        if (TestMethod_SiteContainer.p_Sitea == null)    {        TestMethod_SiteContainer.p_Sitea = CallSite<Func<CallSite, object, object>>.Create(Binder.GetMember(CSharpBinderFlags.None, "X", typeof(Program), new CSharpArgumentInfo[] { CSharpArgumentInfo.Create(CSharpArgumentInfoFlags.None, null) }));    }    object p1x = TestMethod_SiteContainer.p_Sitea.Target(TestMethod_SiteContainer.p_Sitea, p1);        if (TestMethod_SiteContainer.p_Siteb == null)    {        TestMethod_SiteContainer.p_Siteb = CallSite<Func<CallSite, object, object>>.Create(Binder.GetMember(CSharpBinderFlags.None, "Y", typeof(Program), new CSharpArgumentInfo[] { CSharpArgumentInfo.Create(CSharpArgumentInfoFlags.None, null) }));    }    object p1y = TestMethod_SiteContainer.p_Siteb.Target(TestMethod_SiteContainer.p_Siteb, p1);        object p2 = new {        X = 1,        Y = 0x59,        Z = 3    };        if (TestMethod_SiteContainer.p_Sitec == null)    {        TestMethod_SiteContainer.p_Sitec = CallSite<Func<CallSite, object, object>>.Create(Binder.GetMember(CSharpBinderFlags.None, "X", typeof(Program), new CSharpArgumentInfo[] { CSharpArgumentInfo.Create(CSharpArgumentInfoFlags.None, null) }));    }    object p2x = TestMethod_SiteContainer.p_Sitec.Target(TestMethod_SiteContainer.p_Sitec, p2);        if (TestMethod_SiteContainer.p_Sited == null)    {        TestMethod_SiteContainer.p_Sited = CallSite<Func<CallSite, object, object>>.Create(Binder.GetMember(CSharpBinderFlags.None, "Y", typeof(Program), new CSharpArgumentInfo[] { CSharpArgumentInfo.Create(CSharpArgumentInfoFlags.None, null) }));    }    object p2y = TestMethod_SiteContainer.p_Sited.Target(TestMethod_SiteContainer.p_Sited, p2);        if (TestMethod_SiteContainer.p_Sitee == null)    {        TestMethod_SiteContainer.p_Sitee = CallSite<Func<CallSite, object, object>>.Create(Binder.GetMember(CSharpBinderFlags.None, "Z", typeof(Program), new CSharpArgumentInfo[] { CSharpArgumentInfo.Create(CSharpArgumentInfoFlags.None, null) }));    }    object p2z = TestMethod_SiteContainer.p_Sitee.Target(TestMethod_SiteContainer.p_Sitee, p2);}[CompilerGenerated]private static class TestMethod_SiteContainer{    // Fields    public static CallSite<Func<CallSite, object, object>> p_Sitea;    public static CallSite<Func<CallSite, object, object>> p_Siteb;    public static CallSite<Func<CallSite, object, object>> p_Sitec;    public static CallSite<Func<CallSite, object, object>> p_Sited;    public static CallSite<Func<CallSite, object, object>> p_Sitee;}
