Use Rhino Mock to report the function that was called

I have a failing testcase that depends on an external module.
I want to use Rhino Mock to generate a report on called functions.
I created a minimal example that illustrates my problem:
using NUnit.Framework;
using Rhino.Mocks;
using System;
namespace StackOverflow_namespace
{
public interface IUsefulService
{
object HiddenAmongManyCalls();
}
public class ThirdPartyBase
{
private int a = 42;
public ThirdPartyBase(IUsefulService service)
{
object liveFastDieYoung = service.HiddenAmongManyCalls();
liveFastDieYoung.Equals(a);
}
}
public class MyParty : ThirdPartyBase
{
public MyParty(IUsefulService service) : base(service)
{
}
}
[TestFixture]
class StackOverflow
{
[Test]
public void Hypothetical()
{
IUsefulService service = MockRepository.GenerateMock<IUsefulService>();
try
{
var party = new MyParty(service);
}
catch(Exception e)
{
string[] calls = MagicallyGetTheCallsThatWereMadeToTheMock();
foreach(var call in calls)
{
//with my visual studio testrunner for nunit 3 I can investigate stored console output
Console.WriteLine(call);
}
Assert.Fail("Excpexted no exception but was '" + e.GetType().Name + "': " + e.Message);
}
}
private string[] MagicallyGetTheCallsThatWereMadeToTheMock()
{
return new[]
{
"This is where I am lost, I do not know how to get the calls from the repository."
};
}
}
}
I tried to find something online without success.
Do Rhino Mocks record all calls and can I access that list?
Edit:
An attempt to verify Expectations did not work since I am looking for calls I did not expect.
I could build a list of calls using GetArgumentsForCallsMadeOn. I can reflect on the Interface. I started on a method for that but I currently fail to see how I can convert a MethodInfo to an Action<T>.
private IEnumerable<string> GetCallsList<Interface>(Interface rhinomock)
{
Type interfaceType = typeof(Interface);
List<MethodInfo> interfaceMethodInfos = new List<MethodInfo>();
List<string> returnInfos = new List<string>();
StringBuilder callbuilder = new StringBuilder();
foreach (var property in interfaceType.GetProperties())
{
interfaceMethodInfos.Add(property.GetGetMethod());
interfaceMethodInfos.Add(property.GetSetMethod());
}
foreach (var method in interfaceType.GetMethods())
{
interfaceMethodInfos.Add(method);
}
foreach (var methodinfo in interfaceMethodInfos)
{
Action<Interface> magic = null; //convert methodinfo into action - still missing
var calls = rhinomock.GetArgumentsForCallsMadeOn(magic); //magic is currently null, here be crash
foreach (var call in calls)
{
bool more = false;
callbuilder.Clear().Append(interfaceType.Name).Append('.').Append(methodinfo.Name).Append('(');
foreach (var parameter in call)
{
if (more){ callbuilder.Append(", "); }
if (null == parameter) { callbuilder.Append("<null>"); }
else { callbuilder.Append(parameter.ToString()); }
more = true;
}
callbuilder.Append(')');
string callInfo = callbuilder.ToString();
returnInfos.Add(callInfo);
}
}
return returnInfos;
}

I was able to use reflection to get the output I wanted.
Here is the minimal example where the test fails and the output contains all method calls.

service.TestCall2("callA", 1);
service.TestCall2("callB", 1);
object liveFastDieYoung = service.HiddenAmongManyCalls();
service.TestCall2("callA", 2);
service.TestCall2("callB", 2);
var a = service.FULLACCESS;
var b = service.READONLY;
service.FULLACCESS = "some";
liveFastDieYoung.Equals(a);
}

CompileAssemblyFromSource + Obfuscation = don't work

i have working CompileAssemblyFromSource code. But when i use any code protector like RedGate SmartAssembly or Themida it's stop working and i get error "Could not load file or assembly or one of its dependencies". Can you please help me with that?
using System;
using System.CodeDom.Compiler;
using System.Reflection;
using Microsoft.CSharp;
namespace stringToCode
{
public class Program
{
public static int q = 0;
static void Main(string[] args)
{
try
{
string source = "namespace stringToCode { public class FooClass { public void Execute() { Program.q = 1; } } }";
Console.WriteLine("q=" + q);
using (var foo = new CSharpCodeProvider())
{
var parameters = new CompilerParameters();
parameters.GenerateInMemory = true;
foreach (Assembly assembly in AppDomain.CurrentDomain.GetAssemblies())
{
try
{
string location = assembly.Location;
if (!String.IsNullOrEmpty(location))
{
parameters.ReferencedAssemblies.Add(location);
}
}
catch (NotSupportedException)
{ }
}
var res = foo.CompileAssemblyFromSource(parameters, source);
var type = res.CompiledAssembly.GetType("stringToCode.FooClass");
var obj = Activator.CreateInstance(type);
var output = type.GetMethod("Execute").Invoke(obj, new object[] { });
Console.WriteLine("q=" + q);
}
}
catch (Exception e)
{
Console.WriteLine(e.Message);;
}
Console.ReadLine();
}
}
}

sorry for my question. I just understand why it happens)
This is code is example. The main problem i have with code that i get from server.
So when i obfuscate my vars i don't obfuscare them at my "online" code that i use with CompileAssemblyFromSource. So this just can't work. Because vars don't have same names.

Invoke code from string. parameter not accepted

I wish to invoke code that is in selected txt file. It works fine until file content is something simple like "Text string". It also works if i pass string parameter into it. But when i try passing an object like in my case Global it fails. Error is: "The type or namespace name 'Global' could not be found (are you missing a using directive or an assembly reference?)"
Here is some code..
private void button1_Click(object sender, EventArgs e)
{
Scripting scriptObj = new Scripting();
scriptObj.fileName = this.openFileDialog1.FileName;
scriptObj.tekst = File.ReadAllText(this.openFileDialog1.FileName);
string exit = scriptObj.GetAction();
this.label1.Text = exit;
}
namespace WindowsFormsApplication2
{
public class Global
{
public string fileName = "test string";
}
public class Scripting
{
public string tekst = "";
public string fileName = "";
public string MyMethod1(Global obj) { return (obj.fileName); }
public string GetAction()
{
string sourceCode = #" namespace WindowsFormsApplication2 { public class Scripting { public string MyMethod (Global obj) { return (" + tekst + "); }}}";
var compParms = new CompilerParameters
{
GenerateExecutable = false,
GenerateInMemory = true
};
var csProvider = new CSharpCodeProvider();
CompilerResults compilerResults = csProvider.CompileAssemblyFromSource(compParms, sourceCode);
if (compilerResults.Errors.HasErrors)
{
StringBuilder errors = new StringBuilder("Compiler Errors :\r\n");
foreach (CompilerError error in compilerResults.Errors)
{
errors.AppendFormat("Line {0},{1}\t: {2}\n",
error.Line, error.Column, error.ErrorText);
}
return errors.ToString();
}
else
{
Global newGlobal = new Global();
newGlobal.fileName = "TEsTfileNameToOutput";
object typeInstance = compilerResults.CompiledAssembly.CreateInstance("WindowsFormsApplication2.Scripting");
MethodInfo mi = typeInstance.GetType().GetMethod("MyMethod");
string methodOutput = (string)mi.Invoke(typeInstance, new object[]{ newGlobal });
return methodOutput;
}
}
}
}
Why does
public string MyMethod (Global obj) { return (" + tekst + "); }
not take Global as param, but it works ok with MyMethod1
public string MyMethod1(Global obj) { return (obj.fileName); }
Content of selected file is: obj.fileName

You haven't included a reference to the current assembly, which is the assembly declaring Global. Therefore the compiler has no idea which type you're talking about.
You need to set the ReferencedAssemblies property in the CompilerParameters that you're creating.

How can I use a string argument to case a namespace or type?

I need to get some JSON output in a .NET 2.0 C# script. The goal is to use one method to output all the JSON feeds I need. All the models have the same id and name properties so I have about 15 namespaces that have the same parts here. In short: since I'm use castle I can call the function like:
/public/get_place_tags.castle
/public/get_place_types.castle
/public/get_place_whichEver.castle
Which in castle is calling each method, ie: the get_place_tags(){} but I want to not have to work where I can call one method to get output from each type like this:
/public/get_json.castle?wantedtype=place_types
Does anyone know how to fix this?
namespace campusMap.Controllers
{
[Layout("home")]
public class PublicController : BaseController
{
/* works and returns */
public void get_pace_type()
{
CancelView();
CancelLayout();
place_types[] types = ActiveRecordBase<place_types>.FindAll();
List<JsonAutoComplete> type_list = new List<JsonAutoComplete>();
foreach (place_types place_type in types)
{
JsonAutoComplete obj = new JsonAutoComplete();
obj.id = place_type.place_type_id;
obj.label = place_type.name;
obj.value = place_type.name;
type_list.Add(obj);
}
string json = JsonConvert.SerializeObject(type_list);
RenderText(json);
}
/* can;t ever find the namespace */
public void get_json(string wantedtype)
{
CancelView();
CancelLayout();
Type t = Type.GetType(wantedtype);
t[] all_tag = ActiveRecordBase<t>.FindAll();
List<JsonAutoComplete> tag_list = new List<JsonAutoComplete>();
foreach (t tag in all_tag)
{
JsonAutoComplete obj = new JsonAutoComplete();
obj.id = tag.id;
obj.label = tag.name;
obj.value = tag.name;
tag_list.Add(obj);
}
string json = JsonConvert.SerializeObject(tag_list);
RenderText(json);
}
}
}
[EDIT]-- (Newest Idea) Runtime type creation.. This I think is the cleanest idea on a way to get it to work...-----
So the goal is really to have at runtime a type used.. right.. so I thought this would work.
http://www.java2s.com/Code/CSharp/Development-Class/Illustratesruntimetypecreation.htm
and based of that here is the method so far. I'm still having issues getting t to get past the error
"The type or namespace name 't' could not be found (are you missing a using directive or an assembly reference?)" .. not sure where I'm going wrong here. Can't seem to get any of it to work lol..
public void get_json(String TYPE)
{
CancelView();
CancelLayout();
if (String.IsNullOrEmpty(TYPE))
{
TYPE = "place_types";
}
// get the current appdomain
AppDomain ad = AppDomain.CurrentDomain;
// create a new dynamic assembly
AssemblyName an = new AssemblyName();
an.Name = "DynamicRandomAssembly";
AssemblyBuilder ab = ad.DefineDynamicAssembly(an, AssemblyBuilderAccess.Run);
// create a new module to hold code in the assembly
ModuleBuilder mb = ab.DefineDynamicModule("RandomModule");
// create a type in the module
TypeBuilder tb = mb.DefineType(TYPE, TypeAttributes.Public);
// finish creating the type and make it available
Type t = tb.CreateType();
t[] all_tag = ActiveRecordBase<t>.FindAll();
List<JsonAutoComplete> tag_list = new List<JsonAutoComplete>();
foreach (t tag in all_tag)
{
JsonAutoComplete obj = new JsonAutoComplete();
obj.id = tag.id;
obj.label = tag.name;
obj.value = tag.name;
tag_list.Add(obj);
}
RenderText(JsonConvert.SerializeObject(tag_list));
}
[EDIT]-- (Older idea) Eval code-----
So this attempt to make this happen is to use reflection and stuff to do a eval of sorts based on this http://www.codeproject.com/script/Articles/ViewDownloads.aspx?aid=11939
namespace EvalCSCode
{
/// <summary>

OK, this is just a suggestion, and I know nothing about castle but it seems to me that you are wanting a custom route.
This is untested and of course you will have to tweak it but have a look at your Global.asax RegisterRoutes method and add this above you default route
routes.MapRoute(
"TypeRoute", // Route name
"Public/{wantedtype}", // URL with parameters
new { controller = "Public", action = "get_json", wantedtype = UrlParameter.Optional } // Parameter defaults
);
something like this might get what you are after.
you might need to fiddle with the action so it matches your castle framework
EDIT
I had some more time to look at this. Using the route I described above and the following method on the controller I got a good result
public void get_json(string wantedtype)
{
Type t = Type.GetType(wantedtype);
// t.Name = "Int32" when "System.Int32 is used as the wanted type
}
http://.../Public/System.Int32 works,
this url doesn't work http://.../Public/Int32
Now if you wanted to use the short version you could use something like MEF or AutoFAC or Castle to do a lookup in your container for the type you are after.
So my answer is use a good route to get the key for the wanted type then build a factory to manage the type mappings and produce an instance of what you are after.

I just had a look at the ActiveRecord API Doco Here
There is a method FindAll(Type targetType) : Array
have you tried replacing
Type t = Type.GetType(wantedtype);
t[] all_tag = ActiveRecordBase<t>.FindAll();
// blah blah blah
with
Type t = Type.GetType(wantedtype);
dynamic all_tag = ActiveRecordBase.FindAll(t);
RenderText(JsonConvert.SerializeObject(all_tag ));
completely untested but see what you think

I tired and tried and tired to so one of these ways. Me and an co-worker came up this with solution. I made 2 files.

Ijson_autocomplete theclass = (Ijson_autocomplete)Activator.CreateInstance(t);

and one off the models

virtual public IList<place> Places
{
get { return places; }
set { places = value; }
}
}
}
now when you call
/public/get_json.castle?wantedtype=place_types
or
/public/get_json.castle?wantedtype=place_tags
You will get the json output of each model. Tada! :D Thank you everyone for helping.

Passing custom object across AppDomains

I compile a plugin and then create an instance of it in a new AppDomain. Then I want to execute a method in the plugin object but that results in an ArgumentException:
"Object of type System.MarshalByRefObject can not be converted to type Data"
The code below should be compilable and result in the exception above. To make it work you must also sign the Assembly (Project -> Properties -> Signing -> Sign the assembly -> New ...)
IPlugin.cs:
using System;
